Legend: RPn and RPIn represent remappable pins for Peripheral Pin Select (PPS) functions.
Note 1: RD1 is an analog pin and implements the AN35/SEG20/RP24/CN50/RD1 functions. However, there is not an ANSx bit associated with the
RD1 port. Using the RD1 pin for the AN35 function would cause a worst-case increase in device current consumption of 500 µA.

DEVICE OVERVIEW
This document contains device-specific information for
the following devices:
• PIC24FJ64GC006
• PIC24FJ128GC006
• PIC24FJ64GC010
• PIC24FJ128GC010
The PIC24FJ128GC010 family expands the capabilities
of the PIC24F family by adding a complete selection of
advanced analog peripherals to its existing digital
features. This combination, along with its ultra
low-power features, Direct Memory Access (DMA) for
peripherals, USB On-The-Go (OTG) and a built-in LCD
controller and driver, makes this family the new
standard for mixed-signal PIC® microcontrollers in one
economical and power-saving package.
1.1
1.1.1
Aside from these new features, PIC24FJ128GC010
family devices also include all of the legacy power-saving
features of previous PIC24F microcontrollers, such as:
• On-the-Fly Clock Switching, allowing the selection
of a lower power clock during run time
• Doze Mode Operation, for maintaining peripheral
clock speed while slowing the CPU clock
• Instruction-Based Power-Saving modes, for quick
invocation of Idle and the many Sleep modes
1.1.3
Core Features
16-BIT ARCHITECTURE
Central to all PIC24F devices is the 16-bit modified
Harvard architecture, first introduced with Microchip’s
dsPIC® Digital Signal Controllers (DSCs). The PIC24F
CPU core offers a wide range of enhancements, such as:
• 16-bit data and 24-bit address paths with the
ability to move information between data and
memory spaces
• Linear Addressing of up to 12 Mbytes (program
space) and 32 Kbytes (data)
• A 16-element Working register array with built-in
software stack support
• A 17 x 17 hardware multiplier with support for
integer math
• Hardware support for 32 by 16-bit division
• An instruction set that supports multiple
addressing modes and is optimized for high-level
languages, such as ‘C’
• Operational performance up to 16 MIPS
1.1.2
Many of these new low-power modes also support the
continuous operation of the low-power, on-chip
Real-Time Clock and Calendar (RTCC), making it
possible for an application to keep time while the
device is otherwise asleep.
XLP POWER-SAVING TECHNOLOGY
The PIC24FJ128GC010 family of devices introduces a
greatly expanded range of power-saving operating
modes for the ultimate in power conservation. The new
modes include:
• Retention Sleep with essential circuits being
powered from a separate low-voltage regulator
• Retention Deep Sleep, a lower power mode that
maintains data RAM for fast start-up
• Deep Sleep without RTCC for the lowest possible
power consumption under software control
• VBAT mode (with or without RTCC) to continue
limited operation from a backup battery when VDD
is removed
2012-2016 Microchip Technology Inc.
OSCILLATOR OPTIONS AND
FEATURES
All of the devices in the PIC24FJ128GC010 family offer
five different oscillator options, allowing users a range
of choices in developing application hardware. These
include:
• Two Crystal modes
• Two External Clock modes
• A Phase-Locked Loop (PLL) frequency multiplier,
which allows clock speeds of up to 32 MHz
• A Fast Internal Oscillator (FRC) – nominal 8 MHz
output, with multiple frequency divider options and
automatic frequency self-calibration during
run time
• A separate Low-Power Internal RC Oscillator
(LPRC) – 31 kHz nominal, for low-power,
timing-insensitive applications.
The internal oscillator block also provides a stable
reference source for the Fail-Safe Clock Monitor
(FSCM). This option constantly monitors the main clock
source against a reference signal provided by the internal oscillator and enables the controller to switch to the
internal oscillator, allowing for continued low-speed
operation or a safe application shutdown.
1.1.4
EASY MIGRATION
Regardless of the memory size, all devices share the
same rich set of peripherals, allowing for a smooth
migration path as applications grow and evolve. This
extends the ability of applications to grow from the
relatively simple, to the powerful and complex, while
still selecting a Microchip device.
DS30009312D-page 13
PIC24FJ128GC010 FAMILY
1.2
Advanced Analog Features
The centerpiece of the PIC24FJ128GC010 family is the
advanced analog block. This feature set provides application developers with all the tools they need for single
chip applications that demand high analog performance.
Included in the advanced analog block are:
• A new 12-bit Pipeline A/D Converter (A/D)
module. A major departure from previous PIC24F
A/D Converters, this module offers up to
50 single-ended input channels (or up to
25 differential channel pairs) and conversion rates
of up to ten million samples per second. It also
provides a wider range of new features that allow
the converter to assess and make decisions on
incoming data without CPU intervention.
• A dual differential channel, Sigma-Delta A/D
Converter, for applications requiring
high-precision conversions (up to 16-bit resolution).
The Sigma-Delta Converter also offers
programmable gain on each channel pair and
user-configurable data rate, between 244 samples
per second and 62.5 ksps.
• Two independent, 10-bit Digital-to-Analog
Converters (DACs), each capable of conversion
rates up to one million samples per second.
• A comparator module with three analog comparators that are configurable for a wide range of
operations. The comparators also have their own
independent, configurable voltage reference.
• A dual operational amplifier module with multiple
input options, selectable power modes, and
rail-to-rail operation on the inputs and outputs.
Each of the op amps can also be configured to
function as a comparator, complete with interrupt
generation.
• A dedicated, integrated band gap voltage reference for all analog modules, providing a range of
on-chip reference voltages and two buffered
reference outputs.
• Flexible multiplexing options for the entire analog
block, allowing for the convenient sharing of
signals between the analog modules.
DS30009312D-page 14
1.3
DMA Controller
PIC24FJ128GC010 family devices also add a Direct
Memory Access (DMA) controller to the existing
PIC24F architecture. The DMA acts in concert with the
CPU, allowing data to move between data memory and
peripherals without the intervention of the CPU,
increasing data throughput, and decreasing execution
time overhead. Six independently programmable channels make it possible to service multiple peripherals at
virtually the same time, with each channel peripheral
performing a different operation. Many types of data
transfer operations are supported.
1.4
USB On-The-Go (OTG)
USB On-The-Go provides on-chip functionality as a
target device compatible with the USB 2.0 standard, as
well as limited stand-alone functionality as a USB
embedded host. By implementing the USB Host Negotiation Protocol (HNP), the module can also dynamically
switch between device and host operation, allowing
for a much wider range of versatile USB-enabled
applications on a microcontroller platform.
PIC24FJ128GC010 family devices also incorporate an
integrated USB transceiver and precision oscillator,
minimizing the required complexity of implementing a
complete USB device, embedded host, dual role or
On-The-Go application.

LCD Controller
With the PIC24FJ128GC010 family of devices,
Microchip introduces its versatile Liquid Crystal Display
(LCD) controller and driver to the PIC24F family. The
on-chip LCD driver includes many features that make
the integration of displays in low-power applications
easier. These include an integrated voltage regulator
with charge pump and an integrated internal resistor
ladder that allows contrast control in software, and
display operation above device VDD.

Other Special Features
• Peripheral Pin Select (PPS): The Peripheral Pin
Select feature allows most digital peripherals to
be mapped over a fixed set of digital I/O pins.
Users may independently map the input and/or
output of any one of the many digital peripherals
to any one of the I/O pins.
• Communications: The PIC24FJ128GC010
family incorporates several different serial
communication peripherals to handle a range of
application requirements. There are two independent I2C modules that support both Master and
Slave modes of operation. Devices also have,
through the PPS feature, four independent UARTs
with built-in IrDA® encoders/decoders and two SPI
modules.
• CTMU Interface: In addition to their other analog
features, members of the PIC24FJ128GC010
family include the CTMU interface module. This
provides a convenient method for precision time
measurement and pulse generation, and can
serve as an interface for capacitive sensors.
• Enhanced Parallel Master/Parallel Slave Port:
This module allows rapid and transparent access
to the microcontroller data bus, and enables the
CPU to directly address external data memory. The
parallel port can function in Master or Slave mode,
accommodating data widths of 4, 8 or 16 bits, and
address widths of up to 23 bits in Master modes.
• Real-Time Clock and Calendar (RTCC): This
module implements a full-featured clock and
calendar with alarm functions in hardware, freeing
up timer resources and program memory space
for use of the core application.
• Data Signal Modulator (DSM): The Data Signal
Modulator (DSM) allows the user to mix a digital
data stream (the “modulator signal”) with a carrier
signal to produce a modulated output.

Details on Individual Family
Members
Devices in the PIC24FJ128GC010 family are available
in 64-pin and 100/121-pin packages. The general block
diagram for all devices is shown in Figure 1-1.
The devices are differentiated from each other in
six ways:
1.
2.

5.
6.
Flash program memory (64 Kbytes for
PIC24FJ64GC0XX devices and 128 Kbytes for
PIC24FJ128GC0XX devices).
Available I/O pins and ports (53 pins on 6 ports
for 64-pin devices and 85 pins on 7 ports for
100/121-pin devices).
Available Interrupt-on-Change Notification (ICN)
inputs (52 on 64-pin devices and 82 on
100/121-pin devices).
Available remappable pins (29 pins on 64-pin
devices and 44 pins on 100/121-pin devices).
Maximum available drivable LCD pixels (248 for
64-pin devices and 472 on 100/121-pin devices.)
Analog input channels for the Pipeline A/D
Converter (29 channels for 64-pin devices and
50 channels for 100/121-pin devices).
All other features for devices in this family are identical.
These are summarized in Table 1-1 and Table 1-2.
A list of pin features available on the PIC24FJ128GC010
family devices, sorted by function, is shown in Table 1-3.
Note that this table shows the pin location of individual
peripheral features and not how they are multiplexed on
the same pin. This information is provided in the pinout
diagrams in the beginning of the data sheet. Multiplexed
features are sorted by the priority given to a feature, with
the highest priority peripheral being listed first.

2.2.1
Power Supply Pins
DECOUPLING CAPACITORS
The use of decoupling capacitors on every pair of
power supply pins is required. This includes digital
supply (VDD and VSS) and all analog supplies (AVDD,
SVDD, AVSS and SVSS).
Consider the following criteria when using decoupling
capacitors:
• Value and type of capacitor: A 0.1 F (100 nF),
25V or 50V, X7R dielectric ceramic capacitor is
recommended. The capacitor should be a
low-ESR device with a resonance frequency in
the range of 20 MHz and higher.
• Placement on the printed circuit board: The
decoupling capacitors should be placed as close
to the pins as possible. It is recommended to
place the capacitors on the same side of the
board as the device. If space is constricted, the
capacitor can be placed on another layer on the
PCB using a via; however, ensure that the trace
length from the pin to the capacitor is no greater
than 0.25 inch (6 mm).
• Handling high-frequency noise: If the board is
experiencing high-frequency noise (upward of
tens of MHz), add a second ceramic type capacitor in parallel to the above described decoupling
capacitor. The value of the second capacitor can
be in the range of 0.01 F to 0.001 F. Place this
second capacitor next to each primary decoupling
capacitor. In high-speed circuit designs, consider
implementing a pair of capacitances as close to
the power and ground pins as possible
(e.g., 0.1 F in parallel with 0.001 F).
• Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first,
and then to the device pins. This ensures that the
decoupling capacitors are first in the power chain.
Equally important is to keep the trace length
between the capacitor and the power pins to a
minimum, thereby reducing PCB trace
inductance.
2.2.2
BULK CAPACITORS
On boards with power traces running longer than
six inches in length, it is suggested to use a tank capacitor for integrated circuits, including microcontrollers, to
supply a local power source. The value of the tank
capacitor should be determined based on the trace
resistance that connects the power supply source to
the device, and the maximum current drawn by the
device in the application. In other words, select the tank
capacitor so that it meets the acceptable voltage sag at
the device. Typical values range from 4.7 F to 47 F.
DS30009312D-page 34
2.3
Master Clear (MCLR) Pin
The MCLR pin provides two specific device functions:
device Reset, and device programming and debugging. If programming and debugging are not required
in the end application, a direct connection to VDD may
be all that is required. The addition of other components, to help increase the application’s resistance to
spurious Resets from voltage sags, may be beneficial.
A typical configuration is shown in Figure 2-1. Other
circuit designs may be implemented, depending on the
application’s requirements.
During programming and debugging, the resistance
and capacitance that can be added to the pin must
be considered. Device programmers and debuggers
drive the MCLR pin. Consequently, specific voltage
levels (VIH and VIL) and fast signal transitions must
not be adversely affected. Therefore, specific values
of R1 and C1 will need to be adjusted based on the
application and PCB requirements. For example, it is
recommended that the capacitor, C1, be isolated
from the MCLR pin during programming and debugging operations by using a jumper (Figure 2-2). The
jumper is replaced for normal run-time operations.
Any components associated with the MCLR pin
should be placed within 0.25 inch (6 mm) of the pin.

Note 1: R1 10 k is recommended. A suggested

MCLR from the external capacitor, C, in the
event of MCLR pin breakdown, due to
Electrostatic Discharge (ESD) or Electrical
Overstress (EOS). Ensure that the MCLR pin

A low-ESR (< 5Ω) capacitor is required on the VCAP pin
to stabilize the output voltage of the on-chip voltage
regulator. The VCAP pin must not be connected to VDD
and must use a capacitor of 10 µF connected to ground.
The type can be ceramic or tantalum. Suitable examples
of capacitors are shown in Table 2-1. Capacitors with
equivalent specification can be used.

CONSIDERATIONS FOR CERAMIC
CAPACITORS
In recent years, large value, low-voltage, surface-mount
ceramic capacitors have become very cost effective in
sizes up to a few tens of microfarad. The low-ESR, small
physical size and other properties make ceramic
capacitors very attractive in many types of applications.
Ceramic capacitors are suitable for use with the internal voltage regulator of this microcontroller. However,
some care is needed in selecting the capacitor to
ensure that it maintains sufficient capacitance over the
intended operating range of the application.
Typical low-cost, 10 F ceramic capacitors are available
in X5R, X7R and Y5V dielectric ratings (other types are
also available, but are less common). The initial tolerance specifications for these types of capacitors are
often specified as ±10% to ±20% (X5R and X7R) or
-20%/+80% (Y5V). However, the effective capacitance
that these capacitors provide in an application circuit will
also vary based on additional factors, such as the
applied DC bias voltage and the temperature. The total
in-circuit tolerance is, therefore, much wider than the
initial tolerance specification.
The X5R and X7R capacitors typically exhibit satisfactory temperature stability (ex: ±15% over a wide
temperature range, but consult the manufacturer’s data
sheets for exact specifications). However, Y5V capacitors typically have extreme temperature tolerance
specifications of +22%/-82%. Due to the extreme
temperature tolerance, a 10 F nominal rated Y5V type
capacitor may not deliver enough total capacitance to
meet minimum internal voltage regulator stability and
transient response requirements. Therefore, Y5V
capacitors are not recommended for use with the
internal regulator.
In addition to temperature tolerance, the effective
capacitance of large value ceramic capacitors can vary
substantially, based on the amount of DC voltage
applied to the capacitor. This effect can be very significant, but is often overlooked or is not always
documented.
Typical DC bias voltage vs. capacitance graph for X7R
type capacitors is shown in Figure 2-4.

DC Bias Voltage (VDC)
When selecting a ceramic capacitor to be used with the
internal voltage regulator, it is suggested to select a
high-voltage rating, so that the operating voltage is a
small percentage of the maximum rated capacitor
voltage. The minimum DC rating for the ceramic
capacitor on VCAP is 16V. Suggested capacitors are
shown in Table 2-1.
2.5
ICSP Pins
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming (ICSP) and debugging purposes.
It is recommended to keep the trace length between
the ICSP connector and the ICSP pins on the device as
short as possible. If the ICSP connector is expected to
experience an ESD event, a series resistor is recommended, with the value in the range of a few tens of
ohms, not to exceed 100Ω.
Pull-up resistors, series diodes and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communications to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin Voltage Input High
(VIH) and Voltage Input Low (VIL) requirements.
For device emulation, ensure that the “Communication
Channel Select” (i.e., PGECx/PGEDx pins), programmed
into the device, matches the physical connections for the
ICSP to the Microchip debugger/emulator tool.
The MCLR connection from the ICSP header should connect directly to the MCLR pin on the device. A capacitor to
ground (C1 in Figure 2-2) is optional, but if used, may
interfere with ICSP operation if the value exceeds 0.01 F.
In most cases, this capacitor is not required.
For more information on available Microchip
development tools connection requirements, refer to
Section 35.0 “Development Support”.

External Oscillator Pins
FIGURE 2-5:
Many microcontrollers have options for at least two
oscillators: a high-frequency Primary Oscillator and a
low-frequency Secondary Oscillator (refer to
Section 9.0 “Oscillator Configuration” for details).
The oscillator circuit should be placed on the same
side of the board as the device. Place the oscillator
circuit close to the respective oscillator pins with no
more than 0.5 inch (12 mm) between the circuit
components and the pins. The load capacitors should
be placed next to the oscillator itself, on the same side
of the board.
Use a grounded copper pour around the oscillator
circuit to isolate it from surrounding circuits. The
grounded copper pour should be routed directly to the
MCU ground. Do not run any signal traces or power
traces inside the ground pour. Also, if using a two-sided
board, avoid any traces on the other side of the board
where the crystal is placed.
Layout suggestions are shown in Figure 2-5. In-line
packages may be handled with a single-sided layout
that completely encompasses the oscillator pins. With
fine-pitch packages, it is not always possible to completely surround the pins and components. A suitable
solution is to tie the broken guard sections to a mirrored
ground layer. In all cases, the guard trace(s) must be
returned to ground.
In planning the application’s routing and I/O assignments, ensure that adjacent port pins, and other
signals in close proximity to the oscillator, are benign
(i.e., free of high frequencies, short rise and fall times
and other similar noise).

oscillator circuits, please refer to these Microchip

If an ICSP compliant emulator is selected as a debugger, it automatically initializes all of the A/D input pins
(ANx) as “digital” pins. Depending on the particular
device, this is done by setting all bits in the ADxPCFG
register(s) or clearing all bits in the ANSx registers.
All PIC24F devices will have either one or more
ADxPCFG registers or several ANSx registers (one for
each port); no device will have both. Refer to
Section 11.2 “Configuring Analog Port Pins
(ANSx)” for more specific information.
The bits in these registers that correspond to the A/D
pins that initialized the emulator must not be
changed by the user application firmware; otherwise,
communication errors will result between the debugger
and the device.
If your application needs to use certain A/D pins as
analog input pins during the debug session, the user
application must modify the appropriate bits during
initialization of the A/D module, as follows:
• For devices with an ADxPCFG register, clear the
bits corresponding to the pin(s) to be configured
as analog. Do not change any other bits, particularly those corresponding to the PGECx/PGEDx
pair, at any time.
• For devices with ANSx registers, set the bits
corresponding to the pin(s) to be configured as
analog. Do not change any other bits, particularly
those corresponding to the PGECx/PGEDx pair,
at any time.
When a Microchip debugger/emulator is used as a
programmer, the user application firmware must
correctly configure the ADxPCFG or ANSx registers.
Automatic initialization of these registers is only done
during debugger operation. Failure to correctly configure
the register(s) will result in all A/D pins being recognized
as analog input pins, resulting in the port value being
read as a logic ‘0’, which may affect user application
functionality.

Sigma-Delta A/D Connections
The Sigma-Delta A/D Converter has input and power
connections that are independent from the rest of the
microcontroller. These connections are required to use
the converter, and are in addition to the connection and
layout connections provided in Section 2.1 “Basic
Connection Requirements” and Section 2.2 “Power
Supply Pins”.
2.8.1
VOLTAGE AND GROUND
CONNECTIONS
To minimize noise interference, the Sigma-Delta A/D
Converter has independent voltage pins. Converter circuits are supplied through the SVDD pin. Independent
ground return is provided through the SVSS pin.
As with the microcontroller’s VDD/VSS and AVDD/AVSS
pins, bypass capacitors are required on SVDD and SVSS.
Requirements for these capacitors are identical to those
for the VDD/VSS and AVDD/AVSS pins.
It is recommended that designs using the Sigma-Delta
A/D Converter incorporate a separate ground return
path for analog circuits. The analog and digital grounds
may be tied to a single point at the power source.
Analog pins that require grounding should be tied to
this analog return. SVSS can be tied to the digital
ground, along with VSS and AVSS.
2.8.2
ANALOG INPUTS
The analog signals to be converted are connected to the
pins of CH0 and/or CH1. Each channel has inverting and
non-inverting inputs (CHx- and CHx+, respectively), and
is fully differential.
If not used for conversion, CH1+ and CH1- can be used
to supply an external voltage reference to the converter. If an external reference is not used and CH1 is
not needed as a conversion input, both pins should be
connected to the analog ground return.
2.9
Unused I/Os
Unused I/O pins should be configured as outputs and
driven to a logic low state. Alternatively, connect a 1 kΩ
to 10 kΩ resistor to VSS on unused pins and drive the
output to logic low.

Note:
CPU
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24
Family
Reference
Manual”, “CPU with Extended Data
Space (EDS)” (DS39732) which is available from the Microchip web site
(www.microchip.com). The information in
this data sheet supersedes the
information in the FRM.
The PIC24F CPU has a 16-bit (data) modified, Harvard
architecture with an enhanced instruction set and a
24-bit instruction word with a variable length opcode
field. The Program Counter (PC) is 23 bits wide and
addresses up to 4M instructions of user program
memory space. A single-cycle instruction prefetch
mechanism is used to help maintain throughput and
provides predictable execution. All instructions execute
in a single cycle, with the exception of instructions that
change the program flow, the double-word move
(MOV.D) instruction and the table instructions.
Overhead-free program loop constructs are supported
using the REPEAT instructions, which are interruptible
at any point.
PIC24F devices have sixteen, 16-bit Working registers
in the programmer’s model. Each of the Working
registers can act as a data, address or address offset
register. The 16th Working register (W15) operates as
a Software Stack Pointer (SSP) for interrupts and calls.
The lower 32 Kbytes of the Data Space (DS) can be
accessed linearly. The upper 32 Kbytes of the Data
Space are referred to as Extended Data Space to which
the extended data RAM, EPMP memory space or
program memory can be mapped.
The Instruction Set Architecture (ISA) has been
significantly enhanced beyond that of the PIC18, but
maintains an acceptable level of backward compatibility. All PIC18 instructions and addressing modes are
supported, either directly, or through simple macros.
Many of the ISA enhancements have been driven by
compiler efficiency needs.
2012-2016 Microchip Technology Inc.
The core supports Inherent (no operand), Relative,
Literal and Memory Direct Addressing modes, along
with three groups of addressing modes. All modes support Register Direct and various Register Indirect
modes. Each group offers up to seven addressing
modes. Instructions are associated with predefined
addressing modes, depending upon their functional
requirements.
For most instructions, the core is capable of executing
a data (or program data) memory read, a Working register (data) read, a data memory write and a program
(instruction) memory read per instruction cycle. As a
result, three parameter instructions can be supported,
allowing trinary operations (that is, A + B = C) to be
executed in a single cycle.
A high-speed, 17-bit x 17-bit multiplier has been
included to significantly enhance the core arithmetic
capability and throughput. The multiplier supports
Signed, Unsigned and Mixed mode, 16-bit x 16-bit or
8-bit x 8-bit, integer multiplication. All multiply
instructions execute in a single cycle.
The 16-bit ALU has been enhanced with integer divide
assist hardware that supports an iterative non-restoring
divide algorithm. It operates in conjunction with the
REPEAT instruction looping mechanism and a selection
of iterative divide instructions to support 32-bit (or
16-bit), divided by 16-bit, integer signed and unsigned
division. All divide operations require 19 cycles to
complete but are interruptible at any cycle boundary.
The PIC24F has a vectored exception scheme, with up to
8 sources of non-maskable traps and up to 118 interrupt
sources. Each interrupt source can be assigned to one of
seven priority levels.
A block diagram of the CPU is shown in Figure 3-1.
3.1
Programmer’s Model
The programmer’s model for the PIC24F is shown in
Figure 3-2. All registers in the programmer’s model are
memory-mapped and can be manipulated directly by
instructions. A description of each register is provided
in Table 3-1. All registers associated with the
programmer’s model are memory-mapped.

3.3
Arithmetic Logic Unit (ALU)
The PIC24F ALU is 16 bits wide and is capable of addition, subtraction, bit shifts and logic operations. Unless
otherwise mentioned, arithmetic operations are 2’s
complement in nature. Depending on the operation, the
ALU may affect the values of the Carry (C), Zero (Z),
Negative (N), Overflow (OV) and Digit Carry (DC)
Status bits in the SR register. The C and DC Status bits
operate as Borrow and Digit Borrow bits, respectively,
for subtraction operations.
The ALU can perform 8-bit or 16-bit operations,
depending on the mode of the instruction that is used.
Data for the ALU operation can come from the W
register array, or data memory, depending on the
addressing mode of the instruction. Likewise, output
data from the ALU can be written to the W register array
or a data memory location.
The PIC24F CPU incorporates hardware support for
both multiplication and division. This includes a
dedicated hardware multiplier and support hardware
for 16-bit divisor division.
3.3.1
MULTIPLIER
The ALU contains a high-speed, 17-bit x 17-bit
multiplier. It supports unsigned, signed or mixed sign
operation in several multiplication modes:
1.
2.
3.
4.
5.
6.
7.
16-bit x 16-bit signed
16-bit x 16-bit unsigned
16-bit signed x 5-bit (literal) unsigned
16-bit unsigned x 16-bit unsigned
16-bit unsigned x 5-bit (literal) unsigned
16-bit unsigned x 16-bit signed
8-bit unsigned x 8-bit unsigned
TABLE 3-2:
3.3.2
DIVIDER
The divide block supports signed and unsigned integer
divide operations with the following data sizes:
1.
2.
3.
4.
32-bit signed/16-bit signed divide
32-bit unsigned/16-bit unsigned divide
16-bit signed/16-bit signed divide
16-bit unsigned/16-bit unsigned divide
The quotient for all divide instructions ends up in W0
and the remainder in W1. Sixteen-bit signed and
unsigned DIV instructions can specify any W register
for both the 16-bit divisor (Wn), and any W register
(aligned) pair (W(m + 1):Wm) for the 32-bit dividend.
The divide algorithm takes one cycle per bit of divisor,
so both 32-bit/16-bit and 16-bit/16-bit instructions take
the same number of cycles to execute.
3.3.3
MULTIBIT SHIFT SUPPORT
The PIC24F ALU supports both single bit and
single-cycle, multibit arithmetic and logic shifts. Multibit
shifts are implemented using a shifter block, capable of
performing up to a 15-bit arithmetic right shift, or up to
a 15-bit left shift, in a single cycle. All multibit shift
instructions only support Register Direct Addressing for
both the operand source and result destination.
A full summary of instructions that use the shift
operation is provided in Table 3-2.

MEMORY ORGANIZATION
As Harvard architecture devices, PIC24F microcontrollers feature separate program and data memory
spaces and buses. This architecture also allows direct
access of program memory from the Data Space (DS)
during code execution.
4.1
Program Memory Space
The program address memory space of the
PIC24FJ128GC010 family devices is 4M instructions.
The space is addressable by a 24-bit value derived
FIGURE 4-1:
User access to the program memory space is restricted
to the lower half of the address range (000000h to
7FFFFFh). The exception is the use of TBLRD/TBLWT
operations, which use TBLPAG to permit access to
the Configuration bits and Device ID sections of the
configuration memory space.
Memory maps for the PIC24FJ128GC010 family of
devices are shown in Figure 4-1.

PROGRAM MEMORY
ORGANIZATION
4.1.3
In PIC24FJ128GC010 family devices, the top four words
of on-chip program memory are reserved for configuration information. On device Reset, the configuration
information is copied into the appropriate Configuration
register. The addresses of the Flash Configuration Word
for devices in the PIC24FJ128GC010 family are shown
in Table 4-1. Their location in the memory map is shown
with the other memory vectors in Figure 4-1.
The program memory space is organized in
word-addressable blocks. Although it is treated as
24 bits wide, it is more appropriate to think of each
address of the program memory as a lower and upper
word, with the upper byte of the upper word being
unimplemented. The lower word always has an even
address, while the upper word has an odd address
(Figure 4-2).
The Configuration Words in program memory are a
compact format. The actual Configuration bits are
mapped in several different registers in the configuration
memory space. Their order in the Flash Configuration
Words does not reflect a corresponding arrangement in
the configuration space. Additional details on the device
Configuration Words are provided in Section 34.0
“Special Features”.
Program memory addresses are always word-aligned
on the lower word and addresses are incremented or
decremented by two during code execution. This
arrangement also provides compatibility with data
memory space addressing and makes it possible to
access data in the program memory space.
4.1.2
HARD MEMORY VECTORS
TABLE 4-1:
All PIC24F devices reserve the addresses between
000000h and 000200h for hard-coded program execution vectors. A hardware Reset vector is provided to
redirect code execution from the default value of the
PC on device Reset to the actual start of code. A GOTO
instruction is programmed by the user at 000000h with
the actual address for the start of code at 000002h.

PIC24F devices also have two Interrupt Vector Tables

many device interrupt sources to be handled by separate ISRs. A more detailed discussion of the Interrupt

Note:
The upper half of data memory address space (8000h to
FFFFh) is used as a window into the Extended Data
Space (EDS). This allows the microcontroller to directly
access a greater range of data beyond the standard
16-bit address range. EDS is discussed in detail in
Section 4.2.5 “Extended Data Space (EDS)”.
Data Memory Space
This data sheet summarizes the features
of this group of PIC24F devices. It is not
intended to be a comprehensive reference source. For more information, refer
to the “dsPIC33/PIC24 Family Reference
Manual”, “Data Memory with Extended
Data Space (EDS)” (DS39733) which is
available from the Microchip web site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
The lower half of DS is compatible with previous PIC24F
microcontrollers without EDS. All PIC24FJ128GC010
family devices implement 8 Kbytes of data RAM in the
lower half of the DS, from 0800h to 27FFh.
4.2.1
The PIC24F core has a 16-bit wide data memory space,
addressable as a single linear range. The Data Space
(DS) is accessed using two Address Generation Units
(AGUs), one each for read and write operations. The
Data Space memory map is shown in Figure 4-3.
The 16-bit wide data addresses in the data memory
space point to bytes within the Data Space. This gives a
DS address range of 64 Kbytes or 32K words. The lower
half (0000h to 7FFFh) is used for implemented (on-chip)
memory addresses.
FIGURE 4-3:
The data memory space is organized in
byte-addressable, 16-bit wide blocks. Data is aligned in
data memory and registers as 16-bit words, but all Data
Space Effective Addresses (EAs) resolve to bytes. The
Least Significant Bytes (LSBs) of each word have even
addresses, while the Most Significant Bytes (MSBs)
have odd addresses.

DATA MEMORY ORGANIZATION
AND ALIGNMENT
A Sign-Extend (SE) instruction is provided to allow users
to translate 8-bit signed data to 16-bit signed values.
Alternatively, for 16-bit unsigned data, users can clear
the MSB of any W register by executing a Zero-Extend
(ZE) instruction on the appropriate address.
To maintain backward compatibility with PIC® MCUs and
improve Data Space memory usage efficiency, the
PIC24F instruction set supports both word and byte
operations. As a consequence of byte accessibility, all
EA calculations are internally scaled to step through
word-aligned memory. For example, the core recognizes
that Post-Modified Register Indirect Addressing mode
[Ws++] will result in a value of Ws + 1 for byte operations
and Ws + 2 for word operations.
Although most instructions are capable of operating on
word or byte data sizes, it should be noted that some
instructions operate only on words.
4.2.3
The 8-Kbyte area between 0000h and 1FFFh is
referred to as the Near Data Space. Locations in this
space are directly addressable via a 13-bit absolute
address field within all memory direct instructions. The
remainder of the Data Space is addressable indirectly.
Additionally, the whole Data Space is addressable
using MOV instructions, which support Memory Direct
Addressing with a 16-bit address field.
Data byte reads will read the complete word, which
contains the byte, using the LSB of any EA to determine which byte to select. The selected byte is placed
onto the LSB of the data path. That is, data memory
and registers are organized as two parallel, byte-wide
entities with shared (word) address decode but
separate write lines. Data byte writes only write to the
corresponding side of the array or register which
matches the byte address.
4.2.4
All word accesses must be aligned to an even address.
Misaligned word data fetches are not supported, so
care must be taken when mixing byte and word
operations or translating from 8-bit MCU code. If a
misaligned read or write is attempted, an address error
trap will be generated. If the error occurred on a read,
the instruction underway is completed; if it occurred on
a write, the instruction will be executed but the write will
not occur. In either case, a trap is then executed, allowing the system and/or user to examine the machine
state prior to execution of the address Fault.
SPECIAL FUNCTION REGISTER
(SFR) SPACE
The first 2 Kbytes of the Near Data Space, from 0000h
to 07FFh, are primarily occupied with Special Function
Registers (SFRs). These are used by the PIC24F core
and peripheral modules for controlling the operation of
the device.
SFRs are distributed among the modules that they control and are generally grouped together by module. Much
of the SFR space contains unused addresses; these are
read as ‘0’. A diagram of the SFR space, showing where
the SFRs are actually implemented, is shown in
Table 4-2. Each implemented area indicates a 32-byte
region where at least one address is implemented as an
SFR. A complete list of implemented SFRs, including
their addresses, is shown in Tables 4-3 through 4-39.
All byte loads into any W register are loaded into the
LSB. The Most Significant Byte (MSB) is not modified.

EXTENDED DATA SPACE (EDS)
The Extended Data Space (EDS) allows PIC24F
devices to address a much larger range of data than
would otherwise be possible with a 16-bit address
range. EDS includes any additional internal data memory not directly accessible by the lower 32-Kbyte data
address space and any external memory through the
Enhanced Parallel Master Port (EPMP).
In addition, EDS also allows read access to the
program memory space. This feature is called Program
Space Visibility (PSV) and is discussed in detail in
Section 4.3.3 “Reading Data from Program Memory
Using EDS”.
Figure 4-4 displays the entire EDS space. The EDS is
organized as pages, called EDS pages, with one page
equal to the size of the EDS window (32 Kbytes). A
particular EDS page is selected through the Data
Space Read register (DSRPAG) or Data Space Write
register (DSWPAG). For PSV, only the DSRPAG register is used. The combination of the DSRPAG register
value and the 16-bit wide data address forms a 24-bit
Effective Address (EA).
FIGURE 4-4:
Special
Function
Registers
The data addressing range of PIC24FJ128GC010 family
devices depends on the version of the Enhanced
Parallel Master Port (EPMP) implemented on a particular device; this is, in turn, a function of the device pin
count. Table 4-40 lists the total memory accessible
by each of the devices in this family. For more details
on accessing external memory using EPMP, refer to
the “dsPIC33/PIC24 Family Reference Manual”,
“Enhanced Parallel Master Port (EPMP)” (DS39730).

Data Read from EDS
In order to read the data from the EDS space, first, an
Address Pointer is set up by loading the required EDS
page number into the DSRPAG register and assigning
the offset address to one of the W registers. Once the
above assignment is done, the EDS window is enabled
by setting bit 15 of the Working register, assigned with
the offset address; then, the contents of the pointed
EDS location can be read.
Example 4-1 shows how to read a byte, word and
double-word from EDS.
Note:
Figure 4-5 illustrates how the EDS space address is
generated for read operations.
All read operations from EDS space have
an overhead of one instruction cycle.
Therefore, a minimum of two instruction
cycles is required to complete an EDS
read. EDS reads under the REPEAT
instruction: the first two accesses take
three cycles and the subsequent
accesses take one cycle.
When the Most Significant bit (MSb) of EA is ‘1’ and
DSRPAG = 0, the lower 9 bits of DSRPAG are concatenated to the lower 15 bits of the EA to form a 24-bit
EDS space address for read operations.

Data Write into EDS
In order to write data to EDS space, such as in EDS
reads, an Address Pointer is set up by loading the
required EDS page number into the DSWPAG register
and assigning the offset address to one of the W registers. Once the above assignment is done, then the
EDS window is enabled by setting bit 15 of the Working
register, assigned with the offset address, and the
accessed location can be written.
0x8000. While developing code in assembly, care must
be taken to update the Data Space Page registers when
an Address Pointer crosses the page boundary. The ‘C’
compiler keeps track of the addressing, and increments
or decrements the Page registers accordingly, while
accessing contiguous data memory locations.
Note 1: All write operations to EDS are executed
in a single cycle.
2: Use of Read/Modify/Write operation on
any EDS location under a REPEAT
instruction is not supported. For example,
BCLR, BSW, BTG, RLC f, RLNC f, RRC f,
RRNC f, ADD f, SUB f, SUBR f, AND f,
IOR f, XOR f, ASR f, ASL f.
Figure 4-6 illustrates how the EDS space address is
generated for write operations.
When the MSb of EA is ‘1’, the lower 9 bits of DSWPAG
are concatenated to the lower 15 bits of EA to form a
24-bit EDS address for write operations. Example 4-2
shows how to write a byte, word and double-word to
EDS.
3: Use the DSRPAG register while
performing Read/Modify/Write operations.
The Data Space Page registers (DSRPAG/DSWPAG)
do not update automatically while crossing a page
boundary when the rollover happens from 0xFFFF to

Address Error Trap(3)
If the source/destination address is below 8000h, the DSRPAG and DSWPAG registers are not considered.
This Data Space can also be accessed by Direct Addressing.
When the source/destination address is above 8000h and DSRPAG/DSWPAG are ‘0’, an address error
trap will occur.
SOFTWARE STACK
Apart from its use as a Working register, the W15
register in PIC24F devices is also used as a Software
Stack Pointer (SSP). The pointer always points to the
first available free word and grows from lower to higher
addresses. It predecrements for stack pops and postincrements for stack pushes, as shown in Figure 4-7.
Note that for a PC push during any CALL instruction,
the MSB of the PC is zero-extended before the push,
ensuring that the MSB is always clear.
Note:
Comment
Near Data Space(2)
Invalid Address
A PC push during exception processing
will concatenate the SR register to the
MSB of the PC prior to the push.
The Stack Pointer Limit Value register (SPLIM), associated with the Stack Pointer, sets an upper address
boundary for the stack. SPLIM is uninitialized at Reset.
As is the case for the Software Stack Pointer,
SPLIM is forced to ‘0’ as all stack operations must
be word-aligned. Whenever an EA is generated using
W15 as a source or destination pointer, the resulting
address is compared with the value in SPLIM. If the
contents of the Stack Pointer (W15) and the SPLIM register are equal, and a push operation is performed, a
stack error trap will not occur. The stack error trap will
occur on a subsequent push operation. Thus, for
2012-2016 Microchip Technology Inc.
example, if it is desirable to cause a stack error trap
when the stack grows beyond address, 2000h in RAM,
initialize the SPLIM with the value, 1FFEh.
Similarly, a Software Stack Pointer underflow (stack
error) trap is generated when the Stack Pointer address
is found to be less than 0800h. This prevents the stack
from interfering with the SFR space.
A write to the SPLIM register should not be immediately
followed by an indirect read operation using W15.

4.3.1
Interfacing Program and Data
Memory Spaces
ADDRESSING PROGRAM SPACE
Since the address ranges for the data and program
spaces are 16 and 24 bits, respectively, a method is
needed to create a 23-bit or 24-bit program address
from 16-bit data registers. The solution depends on the
interface method to be used.
The PIC24F architecture uses a 24-bit wide program
space and 16-bit wide Data Space. The architecture is
also a modified Harvard scheme, meaning that data
can also be present in the program space. To use this
data successfully, it must be accessed in a way that
preserves the alignment of information in both spaces.
For table operations, the 8-bit Table Memory Page
Address register (TBLPAG) is used to define a 32K word
region within the program space. This is concatenated
with a 16-bit EA to arrive at a full 24-bit program space
address. In this format, the MSBs of TBLPAG are
used to determine if the operation occurs in the user
memory (TBLPAG = 0) or the configuration memory
(TBLPAG = 1).
Aside from normal execution, the PIC24F architecture
provides two methods by which program space can be
accessed during operation:
• Using table instructions to access individual bytes
or words anywhere in the program space
• Remapping a portion of the program space into
the Data Space (Program Space Visibility)
For remapping operations, the 10-bit Extended Data
Space Read register (DSRPAG) is used to define a
16K word page in the program space. When the Most
Significant bit (MSb) of the EA is ‘1’, and the MSb (bit 9)
of DSRPAG is ‘1’, the lower 8 bits of DSRPAG are concatenated with the lower 15 bits of the EA to form a
23-bit program space address. The DSRPAG bit
decides whether the lower word (when the bit is ‘0’) or
the higher word (when the bit is ‘1’) of program memory
is mapped. Unlike table operations, this strictly limits
remapping operations to the user memory area.
Table instructions allow an application to read or write
to small areas of the program memory. This makes the
method ideal for accessing data tables that need to be
updated from time to time. It also allows access to all
bytes of the program word. The remapping method
allows an application to access a large block of data on
a read-only basis, which is ideal for look-ups from a
large table of static data. It can only access the least
significant word of the program word.
Table 4-42 and Figure 4-8 show how the program EA is
created for table operations, and remapping accesses
from the data EA. Here, P refer to a program
space word, whereas D refer to a Data Space
word.

Data EA is always ‘1’ in this case, but is not used in calculating the program space address. Bit 15 of
the address is DSRPAG.
DSRPAG is always ‘1’ in this case. DSRPAG decides whether the lower word or higher word of
program memory is read. When DSRPAG is ‘0’, the lower word is read and when it is ‘1’, the higher
word is read.

DATA ACCESS FROM PROGRAM
MEMORY USING TABLE
INSTRUCTIONS
The TBLRDL and TBLWTL instructions offer a direct
method of reading or writing the lower word of any
address within the program space without going through
Data Space. The TBLRDH and TBLWTH instructions are
the only method to read or write the upper 8 bits of a
program space word as data.
The PC is incremented by two for each successive
24-bit program word. This allows program memory
addresses to directly map to Data Space addresses.
Program memory can thus be regarded as two, 16-bit
word-wide address spaces, residing side by side, each
with the same address range. TBLRDL and TBLWTL
access the space which contains the least significant
data word, and TBLRDH and TBLWTH access the space
which contains the upper data byte.
Two table instructions are provided to move byte or
word-sized (16-bit) data to and from program space.
Both function as either byte or word operations.
1.
TBLRDL (Table Read Low): In Word mode, it
maps the lower word of the program space
location (P) to a data address (D).
In Byte mode, either the upper or lower byte of
the lower program word is mapped to the lower
byte of a data address. The upper byte is
selected when byte select is ‘1’; the lower byte
is selected when it is ‘0’.
FIGURE 4-9:
2.
TBLRDH (Table Read High): In Word mode, it
maps the entire upper word of a program address
(P) to a data address. Note that
D, the ‘phantom’ byte, will always be ‘0’.
In Byte mode, it maps the upper or lower byte of
the program word to D of the data
address, as above. Note that the data will
always be ‘0’ when the upper ‘phantom’ byte is
selected (Byte Select = 1).
In a similar fashion, two table instructions, TBLWTH
and TBLWTL, are used to write individual bytes or
words to a program space address. The details of
their operation are described in Section 6.0 “Flash
Program Memory”.
For all table operations, the area of program memory
space to be accessed is determined by the Table
Memory Page Address register (TBLPAG). TBLPAG
covers the entire program memory space of the
device, including user and configuration spaces. When
TBLPAG = 0, the table page is located in the user
memory space. When TBLPAG = 1, the page is
located in configuration space.
Note:
Only Table Read operations will execute
in the configuration memory space where
Device IDs are located. Table Write
operations are not allowed.

READING DATA FROM PROGRAM
MEMORY USING EDS
The upper 32 Kbytes of Data Space may optionally be
mapped into any 16K word page of the program space.
This provides transparent access of stored constant
data from the Data Space without the need to use
special instructions (i.e., TBLRDL/H).
Program space access through the Data Space occurs
when the MSb of EA is ‘1’ and the DSRPAG is also
‘1’. The lower 8 bits of DSRPAG are concatenated to the
Wn bits to form a 23-bit EA to access program
memory. The DSRPAG bit decides which word
should be addressed; when the bit is ‘0’, the lower word
and when ‘1’, the upper word of the program memory is
accessed.
The entire program memory is divided into 512 EDS
pages, from 200h to 3FFh, each consisting of 16K words
of data. Pages, 200h to 2FFh, correspond to the lower
words of the program memory, while 300h to 3FFh
correspond to the upper words of the program memory.
Using this EDS technique, the entire program memory
can be accessed. Previously, the access to the upper
word of the program memory was not supported.

For operations that use PSV and are executed outside
a REPEAT loop, the MOV and MOV.D instructions will

For operations that use PSV, which are executed inside

• Execution in the first iteration
• Execution in the last iteration
• Execution prior to exiting the loop due to an
interrupt
• Execution upon re-entering the loop after an

Any other iteration of the REPEAT loop will allow the

DIRECT MEMORY ACCESS
CONTROLLER (DMA)
This data sheet summarizes the features of
the PIC24FJ128GC010 family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Direct Memory Access Controller
(DMA)” (DS39742) which is available
from
the
Microchip
web
site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
Note:
The Direct Memory Access (DMA) controller is
designed to service high data throughput peripherals
operating on the SFR bus, allowing them to access
data memory directly and alleviating the need for
CPU-intensive management. By allowing these
data-intensive peripherals to share their own data path,
the main data bus is also deloaded, resulting in
additional power savings.
The DMA controller functions both as a peripheral and
a direct extension of the CPU. It is located on the
microcontroller data bus, between the CPU and DMA
controller-enabled peripherals, with direct access to
SRAM. This partitions the SFR bus into two buses,
allowing the DMA controller access to the DMA
capable peripherals located on the new DMA SFR bus.
The controller serves as a master device on the DMA
SFR bus, controlling data flow from DMA capable
peripherals.
FIGURE 5-1:
The controller also monitors CPU instruction processing directly, allowing it to be aware of when the CPU
requires access to peripherals on the DMA bus, and
automatically relinquishing control to the CPU as
needed. The use of DMA increases the time the
processor can execute code while the DMA is
transferring data.
The DMA controller includes these features:
• Six Multiple Independent and Independently
Programmable Channels
• Concurrent Operation with the CPU (no DMA
caused Wait states)
• DMA Bus Arbitration
• Five Programmable Address modes
• Four Programmable Transfer modes
• Four Flexible Internal Data Transfer modes
• Byte or Word Support for Data Transfer
• 16-Bit Source and Destination Address Register
for Each Channel, Dynamically Updated and
Reloadable
• 16-Bit Transaction Count Register, Dynamically
Updated and Reloadable
• Upper and Lower Address Limit Registers
• Counter Half-Full Level Interrupt
• Software Triggered Transfer
• Null Write mode for Symmetric Buffer Operations
A simplified block diagram of the DMA controller is
shown if Figure 5-1.

5.1
Summary of DMA Operations
The DMA controller is capable of moving data between
addresses according to a number of different parameters. Each of these parameters can be independently
configured for any transaction. In addition, any or all of
the DMA channels can independently perform a different
transaction at the same time. Transactions are classified
by these parameters:
•
•
•
•
Source and destination (SFRs and data RAM)
Data size (byte or word)
Trigger source
Transfer mode (One-Shot, Repeated or
Continuous)
• Addressing modes (Fixed Address or Address
Blocks, with or without Address Increment/
Decrement)
In addition, the DMA controller provides channel priority
arbitration for all channels.
5.1.1
SOURCE AND DESTINATION
Using the DMA controller, data may be moved between
any two addresses in the Data Space. The SFR space
(0000h to 07FFh), or the data RAM space (0800h to
FFFFh) can serve as either the source or the destination. Data can be moved between these areas in either
direction, or between addresses in either area. The four
different combinations are shown in Figure 5-2.
If it is necessary to protect areas of data RAM, the DMA
controller allows the user to set upper and lower address
boundaries for operations in the Data Space above the
SFR space. The boundaries are set by the DMAH and
DMAL Limit registers. If a DMA channel attempts an
operation outside of the address boundaries, the
transaction is terminated and an interrupt is generated.
5.1.2
DATA SIZE
The DMA controller can handle both 8-bit and 16-bit
transactions. Size is user-selectable using the SIZE bit
(DMACHn). By default, each channel is configured
for word-size transactions. When byte-size transactions are chosen, the LSb of the source and/or
destination address determines if the data represents
the upper or lower byte of the data RAM location.
5.1.3
Since the source and destination addresses for any
transaction can be programmed independently of the
trigger source, the DMA controller can use any trigger
to perform an operation on any peripheral. This also
allows DMA channels to be cascaded to perform more
complex transfer operations.
5.1.4
TRANSFER MODE
The DMA controller supports four types of data
transfers, based on the volume of data to be moved for
each trigger.
• One-Shot: A single transaction occurs for each
trigger.
• Continuous: A series of back-to-back transactions
occur for each trigger. The number of transactions
is determined by the DMACNTn Transaction
Counter register.
• Repeated One-Shot: A single transaction is
performed repeatedly, once per trigger, until the
DMA channel is disabled.
• Repeated Continuous: A series of transactions
are performed repeatedly, one cycle per trigger,
until the DMA channel is disabled.
All transfer modes allow the option to have the source
and destination addresses, and counter value automatically reloaded after the completion of a transaction.
Repeated mode transfers do this automatically.
5.1.5
ADDRESSING MODES
The DMA controller also supports transfers between
single addresses or address ranges. The four basic
options are:
• Fixed-to-Fixed: Between two constant addresses
• Fixed-to-Block: From a constant source address
to a range of destination addresses
• Block-to-Fixed: From a range of source
addresses to a single, constant destination
address
• Block-to-Block: From a range to source
addresses to a range of destination addresses
The option to select auto-increment or auto-decrement
of source and/or destination addresses is available for
Block Addressing modes.
TRIGGER SOURCE
The DMA controller can use 63 of the device’s interrupt
sources to initiate a transaction. The DMA trigger
sources occur in reverse order of their natural interrupt
priority and are shown in Table 5-1.
These sources cannot be used as DMA triggers:
• Input Capture 8 and 9
• Output Compare 7, 8 and 9
• USB

5.1.6
CHANNEL PRIORITY
Each DMA channel functions independently of the
others, but also competes with the others for access to
the data and DMA buses. When access collisions
occur, the DMA controller arbitrates between the
channels using a user-selectable priority scheme. Two
schemes are available:
• Round Robin: When two or more channels
collide, the lower numbered channel receives
priority on the first collision. On subsequent collisions, the higher numbered channels each
receive priority based on their channel number.
• Fixed: When two or more channels collide, the
lowest numbered channel always receives
priority, regardless of past history.
5.2
Typical Setup
To set up a DMA channel for a basic data transfer:
1.
Enable the DMA controller (DMAEN = 1) and
select an appropriate channel priority scheme
by setting or clearing PRSSEL.
2. Program DMAH and DMAL with appropriate
upper and lower address boundaries for data
RAM operations.
3. Select the DMA channel to be used and disable
its operation (CHEN = 0).
4. Program the appropriate source and destination
addresses for the transaction into the channel’s
DMASRCn and DMADSTn registers. For PIA
Mode Addressing, use the base address value.
5. Program the DMACNTn register for the number
of triggers per transfer (One-Shot or Continuous
modes) or the number of words (bytes) to be
transferred (Repeated modes).
6. Set or clear the SIZE bit to select the data size.
7. Program the TRMODE bits to select the
Data Transfer mode.
8. Program the SAMODE and DAMODE
bits to select the addressing mode.
9. Enable the DMA channel by setting CHEN.
10. Enable the trigger source interrupt.
DS30009312D-page 86
5.3
Peripheral Module Disable
Unlike other peripheral modules, the channels of the
DMA controller cannot be individually powered down
using the Peripheral Module Disable x (PMDx) registers. Instead, the channels are controlled as two
groups. The DMA0MD bit (PMD7) selectively
controls DMACH0 through DMACH3. The DMA1MD bit
(PMD7) controls DMACH4 and DMACH5. Setting
both bits effectively disables the DMA controller.
5.4
Registers
The DMA controller uses a number of registers to control
its operation. The number of registers depends on the
number of channels implemented for a particular device.
There are always four module-level registers (one
control and three buffer/address registers):
• DMACON: DMA Engine Control Register
(Register 5-1)
• DMAH and DMAL: DMA High and Low Address
Limit Registers
• DMABUF: DMA Data Buffer Register
Each of the DMA channels implements five registers
(two control and three buffer/address registers):
• DMACHn: DMA Channel n Control Register
(Register 5-2)
• DMAINTn: DMA Channel n Interrupt Register
(Register 5-3)
• DMASRCn: DMA Data Source Address Pointer
for Channel n Register
• DMADSTn: DMA Data Destination Source for
Channel n Register
• DMACNTn: DMA Transaction Counter for
Channel n Register
For PIC24FJ128GC010 family devices, there are a
total of 34 DMA registers.

FLASH PROGRAM MEMORY
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24
Family
Reference
Manual”, “PIC24F Flash Program
Memory” (DS30009715) which is available from the Microchip web site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
RTSP is accomplished using TBLRD (Table Read) and
TBLWT (Table Write) instructions. With RTSP, the user
may write program memory data in blocks of 64 instructions (192 bytes) at a time and erase program memory
in blocks of 512 instructions (1536 bytes) at a time.
6.1
Regardless of the method used, all programming of
Flash memory is done with the Table Read and Write
instructions. These allow direct read and write access to
the program memory space from the data memory while
the device is in normal operating mode. The 24-bit target
address in the program memory is formed using the
TBLPAG bits and the Effective Address (EA) from
a W register, specified in the table instruction, as shown
in Figure 6-1.
The PIC24FJ128GC010 family of devices contains
internal Flash program memory for storing and executing application code. The program memory is readable,
writable and erasable. The Flash can be programmed
in three ways:
• In-Circuit Serial Programming™ (ICSP™)
• Run-Time Self-Programming (RTSP)
• Enhanced In-Circuit Serial Programming
(Enhanced ICSP)
The TBLRDL and the TBLWTL instructions are used to
read or write to bits of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
ICSP allows a PIC24FJ128GC010 family device to be
serially programmed while in the end application circuit.
This is simply done with two lines for the programming
clock and programming data (named PGECx and
PGEDx, respectively), and three other lines for power
(VDD), ground (VSS) and Master Clear (MCLR). This
allows customers to manufacture boards with
unprogrammed devices and then program the
FIGURE 6-1:

RTSP Operation
The PIC24F Flash program memory array is organized
into rows of 64 instructions or 192 bytes. RTSP allows
the user to erase blocks of eight rows (512 instructions)
at a time and to program one row at a time. It is also
possible to program single words.
The 8-row erase blocks and single row write blocks are
edge-aligned, from the beginning of program memory, on
boundaries of 1536 bytes and 192 bytes, respectively.
When data is written to program memory using TBLWT
instructions, the data is not written directly to memory.
Instead, data written using Table Writes is stored in
holding latches until the programming sequence is
executed.
Any number of TBLWT instructions can be executed
and a write will be successfully performed. However,
64 TBLWT instructions are required to write the full row
of memory.
To ensure that no data is corrupted during a write,
any unused address should be programmed with
FFFFFFh. This is because the holding latches reset to
an unknown state, so if the addresses are left in the
Reset state, they may overwrite the locations on rows
which were not rewritten.
6.3
Enhanced In-Circuit Serial
Programming
Enhanced In-Circuit Serial Programming uses an
on-board bootloader, known as the Program Executive
(PE), to manage the programming process. Using an
SPI data frame format, the Program Executive can
erase, program and verify program memory. For more
information on Enhanced ICSP, see the device
programming specification.
6.4
Control Registers
There are two SFRs used to read and write the
program Flash memory: NVMCON and NVMKEY.
The NVMCON register (Register 6-1) controls which
blocks are to be erased, which memory type is to be
programmed and when the programming cycle starts.
NVMKEY is a write-only register that is used for write
protection. To start a programming or erase sequence,
the user must consecutively write 55h and AAh to the
NVMKEY register. Refer to Section 6.5 “Programming
Operations” for further details.
The basic sequence for RTSP programming is to set up
a Table Pointer, then do a series of TBLWT instructions
to load the buffers. Programming is performed by
setting the control bits in the NVMCON register.
Data can be loaded in any order and the holding registers
can be written to multiple times before performing a write
operation. Subsequent writes, however, will wipe out any
previous writes.
Note:
Writing to a location multiple times without
erasing is not recommended.
All of the Table Write operations are single-word writes
(2 instruction cycles), because only the buffers are written. A programming cycle is required for programming
each row.

Programming Operations
A complete programming sequence is necessary for
programming or erasing the internal Flash in RTSP
mode. During a programming or erase operation, the
processor stalls (Waits) until the operation is finished.
Setting the WR bit (NVMCON) starts the operation and the WR bit is automatically cleared when the
operation is finished.
6.5.1
5.
PROGRAMMING ALGORITHM FOR
FLASH PROGRAM MEMORY
The user can program one row of Flash program memory
at a time. To do this, it is necessary to erase the 8-row
erase block containing the desired row. The general
process is:
1.
2.
3.
6.
Read eight rows of program memory
(512 instructions) and store in data RAM.
Update the program data in RAM with the
desired new data.
Erase the block (see Example 6-1):
a) Set the NVMOPx bits (NVMCON) to
‘0010’ to configure for the block erase. Set
the ERASE (NVMCON) and WREN
(NVMCON) bits.
b) Write the starting address of the block to be
erased into the TBLPAG and W registers.
c) Write 55h to NVMKEY.
d) Write AAh to NVMKEY.
e) Set the WR bit (NVMCON). The erase
cycle begins and the CPU stalls for the duration of the erase cycle. When the erase is
done, the WR bit is cleared automatically.
EXAMPLE 6-1:
#0x55, W0
W0, NVMKEY
#0xAA, W1
W1, NVMKEY
NVMCON, #WR
DS30009312D-page 94
For protection against accidental operations, the write
initiate sequence for NVMKEY must be used to allow
any erase or program operation to proceed. After the
programming command has been executed, the user
must wait for the programming time until programming
is complete. The two instructions following the start of
the programming sequence should be NOPs, as shown
in Example 6-4.

Write the first 64 instructions from data RAM into
the program memory buffers (see Example 6-3).
Write the program block to Flash memory:
a) Set the NVMOPx bits to ‘0001’ to configure
for row programming. Clear the ERASE bit
and set the WREN bit.
b) Write 55h to NVMKEY.
c) Write AAh to NVMKEY.
d) Set the WR bit. The programming cycle
begins and the CPU stalls for the duration
of the write cycle. When the write to Flash
memory is done, the WR bit is cleared
automatically.
Repeat Steps 4 and 5, using the next available
64 instructions from the block in data RAM by
incrementing the value in TBLPAG, until all
512 instructions are written back to Flash
memory.

USB OTG Module Registers
There are a total of 37 memory-mapped registers associated with the USB OTG module. They can be divided
into four general categories:
•
•
•
•
USB OTG Module Control (12)
USB Interrupt (7)
USB Endpoint Management (16)
USB VBUS Power Control (2)
This total does not include the (up to) 128 BD registers
in the BDT. Their prototypes, described in Register 19-1
and Register 19-2, are shown separately in
Section 19.2 “USB Buffer Descriptors and the BDT”.
DS30009312D-page 282
All USB OTG registers are implemented in the Least
Significant Byte (LSB) of the register. Bits in the upper
byte are unimplemented and have no function. Note
that some registers are instantiated only in Host mode,
while other registers have different bit instantiations
and functions in Device and Host modes.
The registers described in the following sections are
those that have bits with specific control and configuration features. The following registers are used for data
or address values only:
• U1BDTP1: Specifies the 256-word page in data
RAM used for the BDT; 8-bit value with bit 0 fixed
as ‘0’ for boundary alignment.
• U1FRML and U1FRMH: Contain the 11-bit byte
counter for the current data frame.

The modulated output signal is generated by performing a logical AND operation of both the carrier and
modulator signals and then it is provided to the MDOUT
pin. Using this method, the DSM can generate the
following types of key modulation schemes:
DATA SIGNAL MODULATOR
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Data Signal Modulator
(DSM)” (DS39744) which is available
from
the
Microchip
web
site
(www.microchip.com). The information in
this data sheet supersedes the
information in the FRM.
• Frequency Shift Keying (FSK)
• Phase-Shift Keying (PSK)
• On-Off Keying (OOK)
Figure 20-1 shows a simplified block diagram of the
Data Signal Modulator peripheral.
The Data Signal Modulator (DSM) allows the user to
mix a digital data stream (the “modulator signal”) with a
carrier signal to produce a modulated output. Both the
carrier and the modulator signals are supplied to the

ENHANCED PARALLEL
MASTER PORT (EPMP)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Enhanced Parallel Master Port
(EPMP)” (DS39730) which is available
from
the
Microchip
web
site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
The Enhanced Parallel Master Port (EPMP) module provides a parallel, 4-bit (Master mode only), 8-bit (Master
and Slave modes) or 16-bit (Master mode only) data bus
interface to communicate with off-chip modules, such as
memories, FIFOs, LCD controllers and other microcontrollers. This module can serve as either the master or
the slave on the communication bus.
21.1
While all PIC24FJ128GC010 family devices implement
the EPMP, I/O pin constraints place some limits on
16-Bit Master mode operations in some package types.
This is reflected in the number of dedicated Chip Select
pins implemented and the number of dedicated
address lines that are available. The differences are
summarized in Table 21-1. All available EPMP pin
functions are summarized in Table 21-2.
For EPMP Master modes, all external addresses are
mapped into the internal Extended Data Space (EDS).
This is done by allocating a region of the EDS for each
Chip Select (CS) and then assigning each Chip Select
to a particular external resource, such as a memory or
external controller. This region should not be assigned
to another device resource, such as RAM or SFRs. To
perform a write or read on an external resource, the
CPU simply performs a write or read within the address
range assigned for the EPMP.
For 64-pin devices, the dedicated Chip Select pins
(PMCS1 and PMCS2) are not implemented. In addition, only 16 address lines (PMA) are available.
If required, PMA14 and PMA15 can be remapped to
function as PMCS1 and PMCS2, respectively.
The memory space addressable by the device
depends on the number of address lines available, as
well as the number of Chip Select signals required for
the application. Devices with lower pin counts are more
affected by Chip Select requirements, as these take
away address lines. Table 21-1 shows the maximum
addressable range for each pin count.
Key features of the EPMP module are:
• Extended Data Space (EDS) Interface Allows
Direct Access from the CPU
• Up to 23 Programmable Address Lines
• Up to 2 Chip Select Lines
• Up to 2 Acknowledgment Lines
(one per Chip Select)

The user can select between the SOSC crystal
oscillator, LPRC internal oscillator or an external
50 Hz/60 Hz power line input as the clock reference for
the RTCC module. This gives the user an option to trade
off system cost, accuracy and power consumption,
based on the overall system needs.

TABLE 23-2:
RTCC Module Registers
The RTCC module registers are organized into three
categories:
• RTCC Control Registers
• RTCC Value Registers
• Alarm Value Registers
23.2.1
00
REGISTER MAPPING
To limit the register interface, the RTCC Timer and
Alarm Time registers are accessed through corresponding register pointers. The RTCC Value register
window (RTCVALH and RTCVALL) uses the
RTCPTR bits (RCFGCAL) to select the
desired Timer register pair (see Table 23-1).
By writing the RTCVALH byte, the RTCC Pointer value,
the RTCPTR bits decrement by one until they
reach ‘00’. Once they reach ‘00’, the MINUTES and
SECONDS value will be accessible through RTCVALH
and RTCVALL until the pointer value is manually
changed.

Considering that the 16-bit core does not distinguish
between 8-bit and 16-bit read operations, the user must
be aware that when reading either the ALRMVALH or
ALRMVALL bytes, the ALRMPTR value will be
decremented. The same applies to the RTCVALH or
RTCVALL bytes with the RTCPTR bits being
decremented.
Note:
23.2.2
This only applies to read operations and
not write operations.
WRITE LOCK
In order to perform a write to any of the RTCC Timer
registers, the RTCWREN bit (RCFGCAL) must be
set (see Example 23-1).
Note:
The Alarm Value register window (ALRMVALH and
ALRMVALL) uses the ALRMPTR bits
(ALCFGRPT) to select the desired Alarm
register pair (see Table 23-2).
By writing the ALRMVALH byte, the Alarm Pointer
value, ALRMPTR bits, decrement by one until
they reach ‘00’. Once they reach ‘00’, the ALRMMIN
and ALRMSEC value will be accessible through
ALRMVALH and ALRMVALL until the pointer value is
manually changed.
ALRMVAL REGISTER
MAPPING
23.2.3
To avoid accidental writes to the timer, it is
recommended that the RTCWREN bit
(RCFGCAL) is kept clear at any
other time. For the RTCWREN bit to be
set, there is only one instruction cycle time
window allowed between the 55h/AA
sequence and the setting of RTCWREN;
therefore, it is recommended that code
follow the procedure in Example 23-1.
SELECTING RTCC CLOCK SOURCE
The clock source for the RTCC module can be selected
using the RTCLK bits in the RTCPWC register.
When the bits are set to ‘00’, the Secondary Oscillator
(SOSC) is used as the reference clock and when the bits
are ‘01’, LPRC is used as the reference clock. When
RTCLK = 10 and 11, the external power line
(50 Hz and 60 Hz) is used as the clock source.
SETTING THE RTCWREN BIT
(“push w7”);
(“push w8”);
(“disi #5”);
(“mov #0x55, w7”);
(“mov w7, _NVMKEY”);
(“mov #0xAA, w8”);
(“mov w8, _NVMKEY”);
(“bset _RCFGCAL, #13”);
(“pop w8”);
(“pop w7”);
//set the RTCWREN bit

Calibration
The real-time crystal input can be calibrated using the
periodic auto-adjust feature. When properly calibrated,
the RTCC can provide an error of less than 3 seconds
per month. This is accomplished by finding the number
of error clock pulses and storing the value into the
lower half of the RCFGCAL register. The 8-bit signed
value loaded into the lower half of RCFGCAL is
multiplied by four and will either be added or subtracted
from the RTCC timer, once every minute. Refer to the
steps below for RTCC calibration:
1.
2.
3.
Using another timer resource on the device, the
user must find the error of the 32.768 kHz crystal.
Once the error is known, it must be converted to
the number of error clock pulses per minute.
a) If the oscillator is faster than ideal (negative
result from Step 2), the RCFGCAL register value
must be negative. This causes the specified
number of clock pulses to be subtracted from
the timer counter, once every minute.
b) If the oscillator is slower than ideal (positive
result from Step 2), the RCFGCAL register value
must be positive. This causes the specified
number of clock pulses to be subtracted from
the timer counter, once every minute.
EQUATION 23-1:
(Ideal Frequency† – Measured Frequency) * 60 =
Clocks per Minute
† Ideal Frequency = 32,768 Hz
Writes to the lower half of the RCFGCAL register
should only occur when the timer is turned off, or
immediately after the rising edge of the seconds pulse,
except when SECONDS = 00, 15, 30 or 45. This is due
to the auto-adjust of the RTCC at 15 second intervals.
Note:
23.5
It is up to the user to include, in the error
value, the initial error of the crystal: drift
due to temperature and drift due to crystal
aging.
Alarm
• Configurable from half second to one year
• Enabled using the ALRMEN bit
(ALCFGRPT)
• One-time alarm and repeat alarm options
available
2012-2016 Microchip Technology Inc.
23.5.1
CONFIGURING THE ALARM
The alarm feature is enabled using the ALRMEN bit.
This bit is cleared when an alarm is issued. Writes to
ALRMVAL should only take place when ALRMEN = 0.
As shown in Figure 23-2, the interval selection of the
alarm is configured through the AMASK bits
(ALCFGRPT). These bits determine which,
and how many, digits of the alarm must match the clock
value for the alarm to occur.
The alarm can also be configured to repeat based on a
preconfigured interval. The amount of times this
occurs, once the alarm is enabled, is stored in the
ARPT bits (ALCFGRPT). When the value
of the ARPTx bits equals 00h, and the CHIME bit
(ALCFGRPT) is cleared, the repeat function is
disabled and only a single alarm will occur. The alarm
can be repeated, up to 255 times by loading
ARPT with FFh.
After each alarm is issued, the value of the ARPTx bits
is decremented by one. Once the value has reached
00h, the alarm will be issued one last time, after which,
the ALRMEN bit will be cleared automatically and the
alarm will turn off.
Indefinite repetition of the alarm can occur if the
CHIME bit = 1. Instead of the alarm being disabled
when the value of the ARPTx bits reaches 00h, it rolls
over to FFh and continues counting indefinitely while
CHIME is set.
23.5.2
ALARM INTERRUPT
At every alarm event, an interrupt is generated. In
addition, an alarm pulse output is provided that
operates at half the frequency of the alarm. This output
is completely synchronous to the RTCC clock and can
be used as a trigger clock to other peripherals.
Note:
Changing any of the registers, other than
the RCFGCAL and ALCFGRPT registers,
and the CHIME bit, while the alarm is
enabled (ALRMEN = 1), can result in a
false alarm event leading to a false alarm
interrupt. To avoid a false alarm event, the
timer and alarm values should only be
changed while the alarm is disabled
(ALRMEN = 0). It is recommended that
the ALCFGRPT register and CHIME bit be
changed when RTCSYNC = 0.

Power Control
23.7
RTCC VBAT Operation
The RTCC includes a power control feature that allows
the device to periodically wake-up an external device,
wait for the device to be stable before sampling
wake-up events from that device, and then shut down
the external device. This can be done completely
autonomously by the RTCC, without the need to wake
from the current lower power mode (Sleep, Deep
Sleep, etc.).
The RTCC can operate in VBAT mode when there is a
power loss on the VDD pin. The RTCC will continue to
operate if the VBAT pin is powered on (it is usually
connected to the battery).
To use this feature:
The VBAT BOR can be enabled/disabled using the
VBTBOR bit in the CW2 Configuration register
(CW2). If the VBTBOR enable bit is cleared, the
VBAT BOR is always disabled and there will be no
indication of a VBAT BOR. If the VBTBOR bit is set, the
RTCC can receive a Reset and the RTCEN bit will get
cleared; it can happen anywhere between 1.95-1.4V
(typical).
1.
2.
3.
Enable the RTCC (RTCEN = 1).
Set the PWCEN bit (RTCPWC).
Configure the RTCC pin to drive the PWC control
signal (RTCOE = 1 and RTCOUT = 11).
The polarity of the PWC control signal may be chosen
using the PWCPOL bit (RTCPWC). An active-low
or active-high signal may be used with the appropriate
external switch to turn on or off the power to one or
more external devices. The active-low setting may also
be used in conjunction with an open-drain setting on
the RTCC pin, in order to drive the ground pin(s) of the
external device directly (with the appropriate external
VDD pull-up device), without the need for external
switches. Finally, the CHIME bit should be set to enable
the PWC periodicity.
DS30009312D-page 338
Note:
It is recommended to connect the VBAT
pin to VDD if the VBAT mode is not used
(not connected to the battery).

User Interface
POLYNOMIAL INTERFACE
The CRC module can be programmed for CRC
polynomials of up to the 32nd order, using up to 32 bits.
Polynomial length, which reflects the highest exponent
in the equation, is selected by the PLEN bits
(CRCCON2).
The CRCXORL and CRCXORH registers control which
exponent terms are included in the equation. Setting a
particular bit includes that exponent term in the equation. Functionally, this includes an XOR operation on
the corresponding bit in the CRC engine. Clearing the
bit disables the XOR.
For example, consider two CRC polynomials, one a
16-bit and the other a 32-bit equation.
EQUATION 24-1:
DATA INTERFACE
The module incorporates a FIFO that works with a
variable data width. Input data width can be configured
to any value, between 1 and 32 bits, using the
DWIDTH bits (CRCCON2). When the
data width is greater than 15, the FIFO is 4 words deep.
When the DWIDTHx bits are between 15 and 8, the
FIFO is 8 words deep. When the DWIDTHx bits are
less than 8, the FIFO is 16 words deep.
The data for which the CRC is to be calculated must
first be written into the FIFO. Even if the data width is
less than 8, the smallest data element that can be
written into the FIFO is 1 byte. For example, if the
DWIDTHx bits are 5, then the size of the data is
DWIDTH + 1 or 6. The data is written as a whole
byte; the two unused upper bits are ignored by the
module.
Once data is written into the MSb of the CRCDAT registers (that is, the MSb as defined by the data width),
the value of the VWORD bits (CRCCON1)
increments by one. For example, if the DWIDTHx bits
are 24, the VWORDx bits will increment when bit 7 of
CRCDATH is written. Therefore, CRCDATL must
always be written to before CRCDATH.

and
X32+X26 + X23 + X22 + X16 + X12 + X11 + X10 +
X8 + X7 + X5 + X4 + X2 + X + 1
The CRC engine starts shifting data when the CRCGO
bit is set and the value of the VWORDx bits is greater
than zero.
To program these polynomials into the CRC generator,
set the register bits, as shown in Table 24-1.
Each word is copied out of the FIFO into a buffer register,
which decrements the VWORDx bits. The data is then
shifted out of the buffer. The CRC engine continues shifting at a rate of two bits per instruction cycle, until the
VWORDx bits reach zero. This means that for a given
data width, it takes half that number of instructions for
each word to complete the calculation. For example, it
takes 16 cycles to calculate the CRC for a single word of
32-bit data.
Note that the appropriate positions are set to ‘1’ to indicate that they are used in the equation (for example,
X26 and X23). The ‘0’ bit required by the equation is
always XORed; thus, X0 is a don’t care. For a polynomial of length 32, it is assumed that the 32nd bit will
be used. Therefore, the X bits do not have the
32nd bit.
When the VWORDx bits reach the maximum value for
the configured value of the DWIDTHx bits (4, 8 or 16),
the CRCFUL bit becomes set. When the VWORDx bits
reach zero, the CRCMPT bit becomes set. The FIFO is
emptied and the VWORD bits are set to ‘00000’
whenever CRCEN is ‘0’.
At least one instruction cycle must pass after a write to
CRCWDAT before a read of the VWORDx bits is done.

24.1.3
DATA SHIFT DIRECTION
The LENDIAN bit (CRCCON1) is used to control
the shift direction. By default, the CRC will shift data
through the engine, MSb first. Setting LENDIAN (= 1)
causes the CRC to shift data, LSb first. This setting
allows better integration with various communication
schemes and removes the overhead of reversing the
bit order in software. Note that this only changes the
direction the data is shifted into the engine. The result
of the CRC calculation will still be a normal CRC result,
not a reverse CRC result.

INTERRUPT OPERATION
Preload the FIFO by writing to the CRCDATL
and CRCDATH registers until the CRCFUL bit is
set or no data is left.
Clear old results by writing 00h to CRCWDATL
and CRCWDATH. The CRCWDAT registers can
also be left unchanged to resume a previously
halted calculation.
Set the CRCGO bit to start calculation.
Write remaining data into the FIFO as space
becomes available.
When the calculation completes, CRCGO is
automatically cleared. An interrupt will be
generated if CRCISEL = 1.
Read CRCWDATL and CRCWDATH for the
result of the calculation.
The module generates an interrupt that is configurable
by the user for either of two conditions.
8.
If CRCISEL is ‘0’, an interrupt is generated when the
VWORD bits make a transition from a value of ‘1’
to ‘0’. If CRCISEL is ‘1’, an interrupt will be generated
after the CRC operation finishes and the module sets
the CRCGO bit to ‘0’. Manually setting CRCGO to ‘0’
will not generate an interrupt. Note that when an
interrupt occurs, the CRC calculation would not yet be
complete. The module will still need (PLENx + 1)/2
clock cycles after the interrupt is generated until the
CRC calculation is finished.
There are eight registers used to control programmable
CRC operation:

Set the CRCEN bit to enable the module.
Configure the module for desired operation:
a) Program the desired polynomial using the

PLEN bits.
b) Configure the data width and shift direction
using the DWIDTHx and LENDIAN bits.
c) Select the desired Interrupt mode using the
CRCISEL bit.

OVERVIEW OF ADVANCED
ANALOG FEATURES
The defining feature of PIC24FJ128GC010 family
devices is the collection of analog peripherals, designed
to extend the range of PIC24F microcontrollers into
high-performance analog and mixed-signal applications.
All devices include a set of new advanced modules and
several existing analog peripherals, plus a common
voltage reference for ease of use.
The analog block includes four new modules:
• 12-Bit High-Speed, Pipeline A/D Converter
(described in Section 26.0 “12-Bit High-Speed,
Pipeline A/D Converter”)
• 16-Bit Sigma-Delta A/D (described
in Section 27.0 “16-Bit Sigma-Delta

• Dual 10-Bit Digital-to-Analog Converters
(described in Section 28.0 “10-Bit
Digital-to-Analog Converter (DAC)”)
• Dual Operational Amplifiers (described in
Section 29.0 “Dual Operational Amplifier

It also includes these legacy PIC24F analog modules:
• Triple Comparator module (described in
Section 30.0 “Triple Comparator Module”) with
independent voltage reference (described in
Section 31.0 “Comparator Voltage Reference”)
• CTMU (described in Section 32.0 “Charge Time
Measurement Unit (CTMU)”)
A high-level overview of the analog block and its integrating features is shown in Figure 25-1. For a more
detailed diagram of each module and an explanation of
its operation, please refer to the appropriate chapter.
25.1
Shared Analog Pins
Apart from the reserved differential inputs for the
Sigma-Delta A/D Converter, PIC24FJ128GC010 family
devices may have up to 50 analog input channels (in
100-pin devices). Because of the number of analog
features available on the microcontroller, many of the
inputs and outputs of the other advanced analog
modules share pins with these channels.
Table 25-1 describes how features are multiplexed.
Note that not all of these analog channels and their
shared analog peripherals are available on all devices.
25.2
Internal Band Gap References
As an integrating feature, the analog block of the
PIC24FJ128GC010 family devices includes a common
internal voltage reference source. This band gap
provides several functions:
• A single, configurable internal reference source
(BGBUF0) for all on-chip analog consumers
• Two additional and independently programmable
band gap sources that can provide buffered
internal references (BGBUF1 and BGBUF2) to
external pins
• Independent configurability of all sources in Idle,
Sleep and other low-power modes, allowing for
flexibility in power consumption
The reference sources are controlled by three
registers: BUFCON0 for the internal reference
(Register 25-1), and BUFCON1 and BUFCON2
(Register 25-2) for the buffered references.
Additional information for using the analog peripherals
can be found in the following documents:

Guide” (DS00001607)

12-BIT HIGH-SPEED, PIPELINE
A/D CONVERTER
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
Pipeline A/D Converter, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “12-Bit, High-Speed Pipeline A/D
Converter” (DS30000686) which is available from the Microchip web site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
The 12-bit Pipeline A/D Converter has the following key
features:
• Conversion Speeds of up to 10 Msps
• Up to 50 Analog Single-Ended Input Channels or
up to 15 Unique Differential Input Channel Pairs
• 12-Bit Conversion Resolution
• Multiple Internal Reference Input Channels
• External Voltage Reference Input Pins
• Automated Threshold Scan and Compare
Operation to Pre-Evaluate Conversion Results
• Extended Automated and Fully Programmable
Sampling Sequences from up to 4 Different Lists
• Conversion Result Accumulation
• Selectable Conversion Trigger Source
• Internal 32-Word, Configurable Conversion
Result Buffer
• Eight Options for Results Alignment
• Configurable Interrupt Generation
• Operation During CPU Sleep and Idle modes
The A/D Converter module is a 12-bit Pipeline A/D
Converter, capable of sampling up to once per A/D
clock cycle. Its operation is enhanced with a wide range
of automatic sampling options, tighter integration with
other analog modules, result accumulation across
many samples and a configurable results buffer.
A simplified block diagram for the module is shown in
Figure 26-1.
2012-2016 Microchip Technology Inc.
26.1
Basic Operation
To perform a standard A/D conversion:
1.
Configure the module:
a) Configure port pins as analog inputs by
setting the appropriate bits in the ANSx registers (see Section 11.2 “Configuring Analog
Port Pins (ANSx)” for more information).
b) Configure “global” ADCON1, ADCON2 and
ADCON3 control settings, but do not set the
ADON bit until all global settings are
configured:
• Configure A/D clock source/rate
• Select A/D reference sources
• Configure data formatting
• Configure other settings
c) Enable the A/D module by setting the
ADON bit (ADCON1).
d) Wait until the ADREADY bit (ADSTATH)
becomes set, indicating the module is finished
with internal calibration and initialization.
e) Configure Sample List 0 settings, controlled
by the ADL0CONH and ADL0CONL registers, but do not enable the sample list yet
(SLEN):
• Select the desired sample list interrupt
generation settings
• Select a Data Write mode (ex: write all
results to buffer)
• Configure analog sampling time
(SAMC)
• Select a trigger source
• Specify how many entries are in the
sample list (SLSIZE)
• Configure other Sample List 0 specific
settings
f) Initialize the ADTBL0 register (and higher if
SLSIZEx > 0) to select the analog channel(s)
to be included in Sample List 0.
g) Configure and enable A/D interrupts (if
desired):
• Clear the AD1IF and SL0IF bits
• Select an interrupt priority
• Enable AD1IE
h) Enable Sample List 0 by setting the SLEN
bit (ADL0CONL).
i) Generate a trigger event for Sample List 0
(as configured in Step e).
j) Wait for the SL0IF or top level AD1IF interrupt flag to assert, indicating that the A/D
result(s) are now ready.
k) Read the respective result(s) from the appropriate ADRESn register(s) (as configured
based on the BUFORG setting).

26.2
Registers
The Pipeline A/D Converter uses a total of
116 registers. Of these, sixty-nine registers control the
module’s operations; the remainder are data and result
buffers.
Five “global” registers control overall module operation
and provide module status:
• ADCON1 through ADCON3 (Register 26-1
through Register 26-3)
• ADSTATH and ADSTATL (Register 26-4 and
Register 26-5)
Fifty-two registers control sample list selection,
configuration and execution:
• ADLnCONH and ADLnCONL (0 through 3)
(prototypes, Register 26-6 and Register 26-7)
• ADLnSTAT (0 through 3) (prototype, Register 26-8)
• ADLnPTR (0 through 3) (prototype, Register 26-9)
• ADLTLBn (0 through 31) (prototype, Register 26-10)
• ADLnMSEL0 through ADLnMSEL3 (0 through 3)
(prototypes, Register 26-17 through
Register 26-20)
Twelve registers control accumulator and threshold
detect operations:
• ACCONH and ACCONL (Register 26-11 and
Register 26-12)
• ADCHITH and ADCHITL (Register 26-13 and
Register 26-14)
• ADTHnH and ADTHnL (0 through 3) (prototypes,
Register 26-15 and Register 26-16)

2:
Use of the channel switch charge pump is recommended when AVDD < 2.5V.
When set, ADCAL remains set for at least one TAD and is then automatically cleared by hardware.
Manually clearing the bit does not necessarily cancel the calibration routine. Calibration is complete when
ADSTATH = 1.

Not all external analog channels are available on all devices. See Table 1-3 for more information. For 64-pin devices, do
not use the values of ADCH associated with unimplemented channels.
Single-ended and differential conversion returns 000h + offset error.
Single-ended and differential conversion returns 7FFh + offset and gain error.
Single-ended conversion returns 000h and differential conversion returns F800h + offset and gain error.
Channels 124-127 (0x7C-0x7F) should be measured differentially for best results.
Reading VBG/2 requires the previous channel in the sample list to be AVSS. VBG/2 must also be enabled in the SFR,
ANCFG.

MODULE
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to
the “dsPIC33/PIC24 Family Reference
Manual”, “Scalable Comparator Module”
(DS39734) which is available from the
Microchip web site (www.microchip.com).
The information in this data sheet
supersedes the information in the FRM.
The triple comparator module provides three dual input
comparators. The inputs to the comparator can be
configured to use any one of five external analog inputs
(CxINA, CxINB, CxINC, CxIND and VREF+) and a
FIGURE 30-1:
The comparator outputs may be directly connected to
the CxOUT pins. When the respective COE equals ‘1’,
the I/O pad logic makes the unsynchronized output of
the comparator available on the pin.
A simplified block diagram of the module in shown in
Figure 30-1. Diagrams of the possible individual
comparator configurations are shown in Figure 30-2.
Each comparator has its own control register,
CMxCON (Register 30-1), for enabling and configuring
its operation. The output and event status of all three
comparators is provided in the CMSTAT register
(Register 30-2).

Configuring the Comparator
Voltage Reference
The voltage reference module is controlled through the
CVRCON register (Register 31-1). The comparator
voltage reference provides a range of output voltages,
with 32 distinct levels. The comparator reference supply voltage can come from either VDD and VSS, or the
external CVREF+ and CVREF- pins. The voltage source
is selected by the CVRSS bit (CVRCON).
The settling time of the comparator voltage reference
must be considered when changing the CVREF
output.

CHARGE TIME
MEASUREMENT UNIT (CTMU)
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
Charge Measurement Unit, refer to the
“dsPIC33/PIC24 Family Reference Manual”, “Charge Time Measurement Unit
(CTMU) and CTMU Operation with
Threshold Detect” (DS30009743) which
is available from the Microchip web site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
The Charge Time Measurement Unit (CTMU) is a flexible
analog module that provides charge measurement,
accurate differential time measurement between pulse
sources and asynchronous pulse generation. Its key
features include:
•
•
•
•
Thirteen External Edge Input Trigger Sources
Polarity Control for each Edge Source
Control of Edge Sequence
Control of Response to Edge Levels or
Edge Transitions
• Time Measurement Resolution of
One Nanosecond
• Accurate Current Source suitable for Capacitive
Measurement
Together with other on-chip analog modules, the CTMU
can be used to precisely measure time, measure
capacitance, measure relative changes in capacitance
or generate output pulses that are independent of the
system clock. The CTMU module is ideal for interfacing
with capacitive-based touch sensors.
The CTMU is controlled through three registers:
CTMUCON1, CTMUCON2 and CTMUICON.
CTMUCON1 enables the module and controls the
mode of operation of the CTMU, as well as controlling
edge sequencing. CTMUCON2 controls edge source
selection and edge source polarity selection. The
CTMUICON register selects the current range of
current source and trims the current.
2012-2016 Microchip Technology Inc.
32.1
Measuring Capacitance
The CTMU module measures capacitance by
generating an output pulse with a width equal to the
time between edge events on two separate input
channels. The pulse edge events to both input
channels can be selected from four sources: two
internal peripheral modules (OC1 and Timer1) and up
to 13 external pins (CTEDG1 through CTEDG13). This
pulse is used with the module’s precision current
source to calculate capacitance according to the
relationship:
EQUATION 32-1:
dV
I = C ------dT
For capacitance measurements, the A/D Converter
samples an external Capacitor (CAPP) on one of its input
channels after the CTMU output’s pulse. A Precision
Resistor (RPR) provides current source calibration on a
second A/D channel. After the pulse ends, the converter
determines the voltage on the capacitor. The actual
calculation of capacitance is performed in software by
the application.
Figure 32-1 illustrates the external connections used
for capacitance measurements, and how the CTMU
and A/D modules are related in this application. This
example also shows the edge events coming from
Timer1, but other configurations using external edge
sources are possible. A detailed discussion on
measuring capacitance and time with the CTMU
module is provided in the “dsPIC33/PIC24 Family Reference Manual”, “Charge Time Measurement Unit
(CTMU) and CTMU Operation with Threshold
Detect” (DS30009743).
Note:
Only odd numbered ANx channels (AN1,
AN3 to AN15) are connected to the CTMU
during single-ended measurements.

Measuring Time
Time measurements on the pulse width can be similarly
performed using the A/D module’s internal Capacitor
(CAD) and a precision resistor for current calibration.
Figure 32-3 displays the external connections used for
time measurements, and how the CTMU and A/D
modules are related in this application. This example
also shows both edge events coming from the external
CTEDGx pins, but other configurations using internal
edge sources are possible.
32.3
Pulse Generation and Delay
The CTMU module can also generate an output pulse
with edges that are not synchronous with the device’s
system clock. More specifically, it can generate a pulse
with a programmable delay from an edge event input to
the module.
DS30009312D-page 394
When the module is configured for pulse generation
delay by setting the TGEN bit (CTMUCON1), the
internal current source is connected to the B input of
Comparator 2. A Capacitor (CDELAY) is connected to
the Comparator 2 pin, C2INB, and the Comparator
Voltage Reference, CVREF, is connected to C2INA.
CVREF is then configured for a specific trip point. The
module begins to charge CDELAY when an edge event
is detected. When CDELAY charges above the CVREF
trip point, a pulse is output on CTPLS. The length of the
pulse delay is determined by the value of CDELAY and
the CVREF trip point.
Figure 32-4 illustrates the external connections for
pulse generation, as well as the relationship of the
different analog modules required. While CTED1 is
shown as the input pulse source, other options are
available. A detailed discussion on pulse generation
with the CTMU module is provided in the “dsPIC33/
PIC24 Family Reference Manual”.

32.4
Measuring Die Temperature
The CTMU can be configured to use the 12-bit Pipeline
A/D to measure the die temperature using dedicated
A/D Channel 50. Perform the following steps to
measure the diode voltage:
• The internal current source must be set for either
5.5 µA (IRNG = 0x2) or 55 µA
(IRNG = 0x3).
• In order to route the current source to the diode,
the EDG1STAT and EDG2STAT bits must be
equal (either both ‘0’ or both ‘1’).
• The CTMEN bit in the A/D sample list
(ADLnCONH) must be set to ‘0’.
• Due to the high noise floor of the Pipeline A/D, it is
recommended to average at least 8 readings of
the diode voltage before calculating the
temperature.
• The A/D Channel Select bits must be 50 (‘0x32’)
using a single-ended measurement.
The voltage of the diode will vary over temperature
according to the graphs shown below. Note that the
graphs are different, based on the magnitude of the
current source selected. The slopes are nearly linear
over the range of -40ºC to +100ºC and the temperature
can be calculated as follows:
EQUATION 32-2:
For 5.5 µA Current Source:
Tdie =
710 mV – Vdiode
1.8
where Vdiode is in mV, Tdie is in ºC
For 55 µA Current Source:
Tdie =
760 mV – Vdiode
1.55
where Vdiode is in mV, Tdie is in ºC

The High/Low-Voltage Detect (HLVD) module is a
programmable circuit that allows the user to specify
both the device voltage trip point and the direction of
change.
HIGH/LOW-VOLTAGE DETECT
(HLVD)
Note:
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information on the
High/Low-Voltage Detect, refer to the
“dsPIC33/PIC24
Family
Reference
Manual”, “High-Level Integration with
Programmable High/Low-Voltage Detect
(HLVD)” (DS39725) which is available
from
the
Microchip
web
site
(www.microchip.com). The information in
this data sheet supersedes the information
in the FRM.
FIGURE 33-1:
VDD
An interrupt flag is set if the device experiences an
excursion past the trip point in the direction of change.
If the interrupt is enabled, the program execution will
branch to the interrupt vector address and the software
can then respond to the interrupt.
The HLVD Control register (see Register 33-1)
completely controls the operation of the HLVD module.
This allows the circuitry to be “turned off” by the user
under software control, which minimizes the current
consumption for the device.

SPECIAL FEATURES
This data sheet summarizes the features of
this group of PIC24F devices. It is not
intended to be a comprehensive reference
source. For more information, refer to the
following sections of the “dsPIC33/PIC24
Family Reference Manual”.
In PIC24FJ128GC010 family devices, the Configuration bytes are implemented as volatile memory. This
means that configuration data must be programmed
each time the device is powered up. Configuration data
is stored in the four words at the top of the on-chip
program memory space, known as the Flash Configuration Words. Their specific locations are shown in
Table 34-1. These are packed representations of the
actual device Configuration bits, whose actual
locations are distributed among several locations in
configuration space. The configuration data is automatically loaded from the Flash Configuration Words to the
proper Configuration registers during device Resets.
• “Watchdog Timer (WDT)”
(DS39697)
• “High-Level Device Integration”
(DS39719)
• “Programming and Diagnostics”
(DS39716)
which are available from the Microchip
web site (www.microchip.com). The
information in this data sheet
supersedes the information in the
FRMs.

Configuration data is reloaded on every
device Reset.
When creating applications for these devices, users
should always specifically allocate the location of the
Flash Configuration Word for configuration data. This is
to make certain that program code is not stored in this
address when the code is compiled.
PIC24FJ128GC010 family devices include several
features intended to maximize application flexibility and
reliability, and minimize cost through elimination of
external components. These are:

CONSIDERATIONS FOR
CONFIGURING PIC24FJ128GC010
FAMILY DEVICES
The upper byte of all Flash Configuration Words in
program memory should always be ‘0000 0000’. This
makes them appear to be NOP instructions in the
remote event that their locations are ever executed by
accident. Since Configuration bits are not implemented
in the corresponding locations, writing ‘0’s to these
locations has no effect on device operation.
Configuration Bits
Note:
The Configuration bits can be programmed (read as ‘0’),
or left unprogrammed (read as ‘1’), to select various
device configurations. These bits are mapped, starting
at program memory location, F80000h. A detailed explanation of the various bit functions is provided in
Register 34-1 through Register 34-6.
Performing a page erase operation on the
last page of program memory clears the
Flash Configuration Words, enabling code
protection as a result. Therefore, users
should avoid performing page erase
operations on the last page of program
memory.
Note that address, F80000h, is beyond the user program
memory space. In fact, it belongs to the configuration
memory space (800000h-FFFFFFh), which can only be
accessed using Table Reads and Table Writes.

34.2
On-Chip Voltage Regulator
All PIC24FJ128GC010 family devices power their core
digital logic at a nominal 1.8V. To simplify system
design, all devices in the PIC24FJ128GC010 family
incorporate an on-chip regulator that allows the device
to run its core logic from VDD.
This regulator is always enabled. It provides a constant
voltage (1.8V nominal) to the digital core logic, from a
VDD of 2.0V, all the way up to the device’s VDDMAX. It
does not have the capability to boost VDD levels. In
order to prevent “brown-out” conditions when the voltage drops too low for the regulator, the Brown-out
Reset occurs. Then the regulator output follows VDD
with a typical voltage drop of 300 mV.
A low-ESR capacitor (such as ceramic) must be
connected to the VCAP pin (Figure 34-1). This helps to
maintain the stability of the regulator. The recommended
value for the filter capacitor (CEFC) is provided in
Section 2.4 “Voltage Regulator Pin (VCAP)”.

This is a typical operating voltage. Refer to
Section 37.0 “Electrical Characteristics”
for the full operating ranges of VDD.
34.2.1
ON-CHIP REGULATOR AND POR
The voltage regulator requires a small amount of time
to transition from a disabled or standby state into normal operating mode. During this time, designated as
TVREG, code execution is disabled. TVREG is applied
every time the device resumes operation after any
power-down, including Sleep mode. TVREG is determined by the status of the PMSLP bit (RCON).
Refer to Section 37.0 “Electrical Characteristics” for
more information on TVREG.
Note:
34.2.2
For more information, see Section 37.0
“Electrical Characteristics”. The Information in this data sheet supersedes the
information in the “dsPIC33/PIC24 Family
Reference Manual”.
VOLTAGE REGULATOR STANDBY
MODE
The on-chip regulator always consumes a small incremental amount of current over IDD/IPD, including when
the device is in Sleep mode, even though the core
digital logic does not require power. To provide additional savings in applications where power resources
are critical, the regulator can be made to enter Standby
mode on its own whenever the device goes into Sleep
mode. This feature is controlled by the PMSLP bit
(RCON). Clearing the PMSLP bit enables the
Standby mode. When waking up from Standby mode,
the regulator needs to wait for TVREG to expire before
wake-up.
34.2.3
LOW-VOLTAGE/RETENTION
REGULATOR
When power-saving modes, such as Sleep and Deep
Sleep are used, PIC24FJ128GC010 family devices
may use a separate low-power, low-voltage/retention
regulator to power critical circuits. This regulator, which
operates at 1.2V nominal, maintains power to data
RAM and the RTCC while all other core digital logic is
powered down. It operates only in Sleep, Deep Sleep
and VBAT modes.
The low-voltage/retention regulator is described in
more detail in Section 10.1.3 “Low-Voltage/Retention
Regulator”.

PIC24FJ128GC010 FAMILY
34.3
Watchdog Timer (WDT)
For PIC24FJ128GC010 family devices, the WDT is
driven by the LPRC Oscillator. When the WDT is
enabled, the clock source is automatically enabled.
The nominal WDT clock source is the LPRC (31 kHz).
This feeds a prescaler that can be configured for either
5-bit (divide-by-32) or 7-bit (divide-by-128) operation.
The prescaler is set by the FWPSA Configuration bit.
With a 31 kHz input, the prescaler yields a nominal
WDT Time-out period (TWDT) of 1 ms in 5-bit mode or
4 ms in 7-bit mode.
A variable postscaler divides down the WDT prescaler
output and allows for a wide range of time-out periods.
The postscaler is controlled by the WDTPS Configuration bits (CW1), which allows the selection
of a total of 16 settings, from 1:1 to 1:32,768. Using the
prescaler and postscaler time-out periods, ranges from
1 ms to 131 seconds can be achieved.
The WDT Flag bit, WDTO (RCON), is not automatically cleared following a WDT time-out. To detect
subsequent WDT events, the flag must be cleared in
software.
Note:
34.3.1
The CLRWDT and PWRSAV instructions
clear the prescaler and postscaler counts
when executed.
WINDOWED OPERATION
The Watchdog Timer has an optional Fixed Window
mode of operation. In this Windowed mode, CLRWDT
instructions can only reset the WDT during the last 1/4
of the programmed WDT period. A CLRWDT instruction
executed before that window causes a WDT Reset,
similar to a WDT time-out.
Windowed WDT mode is enabled by programming the
WINDIS Configuration bit (CW1) to ‘0’.
The WDT, prescaler and postscaler are reset:
34.3.2
• On any device Reset
• On the completion of a clock switch, whether
invoked by software (i.e., setting the OSWEN bit
after changing the NOSCx bits) or by hardware
(i.e., Fail-Safe Clock Monitor)
• When a PWRSAV instruction is executed
(i.e., Sleep or Idle mode is entered)
• When the device exits Sleep or Idle mode to
resume normal operation
• By a CLRWDT instruction during normal execution
The WDT is enabled or disabled by the FWDTEN
Configuration bits. When the Configuration bits,
FWDTEN = 11, the WDT is always enabled.
If the WDT is enabled, it will continue to run during
Sleep or Idle modes. When the WDT time-out occurs,
the device will wake the device and code execution will
continue from where the PWRSAV instruction was
executed. The corresponding SLEEP or IDLE
(RCON) bit will need to be cleared in software
after the device wakes up.
FIGURE 34-2:
CONTROL REGISTER
The WDT can be optionally controlled in software when
the Configuration bits, FWDTEN = 10. When
FWDTEN = 00, the Watchdog Timer is always
disabled. The WDT is enabled in software by setting
the SWDTEN control bit (RCON). The SWDTEN
control bit is cleared on any device Reset. The software
WDT option allows the user to enable the WDT for
critical Code Segments and disable the WDT during
non-critical segments for maximum power savings.

34.4
Program Verification and
Code Protection
PIC24FJ128GC010 family devices provide two complimentary methods to protect application code from
overwrites and erasures. These also help to protect the
device from inadvertent configuration changes during
run time.
34.4.1
GENERAL SEGMENT PROTECTION
For all devices in the PIC24FJ128GC010 family, the
on-chip program memory space is treated as a single
block, known as the General Segment (GS). Code protection for this block is controlled by one Configuration
bit, GCP. This bit inhibits external reads and writes to
the program memory space. It has no direct effect in
normal execution mode.
Write protection is controlled by the GWRP bit in the
Configuration Word. When GWRP is programmed to
‘0’, internal write and erase operations to program
memory are blocked.
34.4.2
CODE SEGMENT PROTECTION
In addition to global General Segment protection, a
separate subrange of the program memory space can
be individually protected against writes and erases.
This area can be used for many purposes where a
separate block of write and erase-protected code is
needed, such as bootloader applications. Unlike
common boot block implementations, the specially
protected segment in the PIC24FJ128GC010 family
devices can be located by the user anywhere in the
program space and configured in a wide range of sizes.
Code Segment (CS) protection provides an added level
of protection to a designated area of program memory
by disabling the NVM safety interlock whenever a write
or erase address falls within a specified range. It does
not override General Segment protection, controlled by
the GCP or GWRP bit. For example, if GCP and GWRP
are enabled, enabling segmented code protection for
the bottom half of program memory does not undo
General Segment protection for the top half.
The size and type of protection for the segmented code
range are configured by the WPFPx, WPEND, WPCFG
and WPDIS bits in Configuration Word 3. Code Segment protection is enabled by programming the WPDIS
bit (= 0). The WPFPx bits specify the size of the
segment to be protected by specifying the 512-word
code page that is the start or end of the protected
segment. The specified region is inclusive, therefore,
this page will also be protected.
The WPEND bit determines if the protected segment
uses the top or bottom of the program space as a
boundary. Programming WPEND (= 0) sets the bottom
of program memory (000000h) as the lower boundary
of the protected segment. Leaving WPEND unprogrammed (= 1) protects the specified page through the
last page of implemented program memory, including
the Configuration Word locations.
A separate bit, WPCFG, is used to protect the last page
of program space, including the Flash Configuration
Words. Programming WPCFG (= 0) protects the last
page in addition to the pages selected by the WPEND
and WPFP bits’ setting. This is useful in circumstances where write protection is needed for both the
Code Segment in the bottom of the memory and the
Flash Configuration Words.
The various options for Code Segment protection are
shown in Table 34-2.

34.4.3
CONFIGURATION REGISTER
PROTECTION
The Configuration registers are protected against
inadvertent or unwanted changes or reads in two ways.
The primary protection method is the same as that of
the RPn/RPIn registers – shadow registers contain a
complimentary value which is constantly compared
with the actual value.
To safeguard against unpredictable events, Configuration bit changes resulting from individual cell-level
disruptions (such as ESD events) will cause a parity
error and trigger a device Reset.
The data for the Configuration registers is derived from
the Flash Configuration Words in program memory.
When the GCP bit is set, the source data for device
configuration is also protected as a consequence. Even
if General Segment protection is not enabled, the
device configuration can be protected by using the
appropriate Code Segment protection setting.
34.5
JTAG Interface
PIC24FJ128GC010 family devices implement a JTAG
interface, which supports boundary scan device
testing.
DS30009312D-page 416
34.6
In-Circuit Serial Programming™
PIC24FJ128GC010 family microcontrollers can be
serially programmed while in the end application circuit.
This is simply done with two lines for clock (PGECx)
and data (PGEDx), and three other lines for power
(VDD), ground (VSS) and MCLR. This allows customers
to manufacture boards with unprogrammed devices
and then program the microcontroller just before
shipping the product. This also allows the most recent
firmware or a custom firmware to be programmed.
34.7
In-Circuit Debugger
When MPLAB® ICD 3 is selected as a debugger, the
in-circuit debugging functionality is enabled. This function allows simple debugging functions when used with
MPLAB X IDE. Debugging functionality is controlled
through the PGECx (Emulation/Debug Clock) and
PGEDx (Emulation/Debug Data) pins.
To use the in-circuit debugger function of the device,
the design must implement ICSP™ connections to
MCLR, VDD, VSS and the PGECx/PGEDx pin pair,
designated by the ICSx Configuration bits. In addition,
when the feature is enabled, some of the resources are
not available for general use. These resources include
the first 80 bytes of data RAM and two I/O pins.

package types. The ICSP cable assembly is included
as a standard item. In Stand-Alone mode, the MPLAB
PM3 Device Programmer can read, verify and program
PIC devices without a PC connection. It can also set
code protection in this mode. The MPLAB PM3
connects to the host PC via an RS-232 or USB cable.
The MPLAB PM3 has high-speed communications and
optimized algorithms for quick programming of large
memory devices, and incorporates an MMC card for file
storage and data applications.

INSTRUCTION SET SUMMARY
This chapter is a brief summary of the
PIC24F Instruction Set Architecture (ISA)
and is not intended to be a comprehensive
reference source.
The PIC24F instruction set adds many enhancements
to the previous PIC® MCU instruction sets, while maintaining an easy migration from previous PIC MCU
instruction sets. Most instructions are a single program
memory word. Only three instructions require two
program memory locations.
Each single-word instruction is a 24-bit word divided
into an 8-bit opcode, which specifies the instruction
type and one or more operands, which further specify
the operation of the instruction. The instruction set is
highly orthogonal and is grouped into four basic
categories:
•
•
•
•
• A literal value to be loaded into a W register or file
register (specified by the value of ‘k’)
• The W register or file register where the literal
value is to be loaded (specified by ‘Wb’ or ‘f’)
However, literal instructions that involve arithmetic or
logical operations use some of the following operands:
• The first source operand, which is a register, ‘Wb’,
without any address modifier
• The second source operand, which is a literal
value
• The destination of the result (only if not the same
as the first source operand), which is typically a
register, ‘Wd’, with or without an address modifier
The control instructions may use some of the following
operands:
• A program memory address
• The mode of the Table Read and Table Write
instructions
Word or byte-oriented operations
Bit-oriented operations
Literal operations
Control operations
Table 36-1 shows the general symbols used in
describing the instructions. The PIC24F instruction set
summary in Table 36-2 lists all the instructions, along
with the status flags affected by each instruction.
Most word or byte-oriented W register instructions
(including barrel shift instructions) have three
operands:
• The first source operand, which is typically a
register, ‘Wb’, without any address modifier
• The second source operand, which is typically a
register, ‘Ws’, with or without an address modifier
• The destination of the result, which is typically a
register, ‘Wd’, with or without an address modifier
However, word or byte-oriented file register instructions
have two operands:
• The file register specified by the value, ‘f’
• The destination, which could either be the file
register, ‘f’, or the W0 register, which is denoted
as ‘WREG’
Most bit-oriented instructions (including
rotate/shift instructions) have two operands:
The literal instructions that involve data movement may
use some of the following operands:
All instructions are a single word, except for certain
double-word instructions, which were made
double-word instructions so that all the required information is available in these 48 bits. In the second word,
the 8 MSbs are ‘0’s. If this second word is executed as
an instruction (by itself), it will execute as a NOP.
Most single-word instructions are executed in a single
instruction cycle, unless a conditional test is true or the
Program Counter is changed as a result of the instruction.
In these cases, the execution takes two instruction cycles,
with the additional instruction cycle(s) executed as a NOP.
Notable exceptions are the BRA (unconditional/computed
branch), indirect CALL/GOTO, all Table Reads and Writes,
and RETURN/RETFIE instructions, which are single-word
instructions but take two or three cycles.
Certain instructions that involve skipping over the subsequent instruction require either two or three cycles if
the skip is performed, depending on whether the
instruction being skipped is a single-word or two-word
instruction. Moreover, double-word moves require
two cycles. The double-word instructions execute in
two instruction cycles.
simple
• The W register (with or without an address
modifier) or file register (specified by the value of
‘Ws’ or ‘f’)
• The bit in the W register or file register
(specified by a literal value or indirectly by the
contents of register, ‘Wb’)

ELECTRICAL CHARACTERISTICS
This section provides an overview of the PIC24FJ128GC010 family electrical characteristics. Additional information will
be provided in future revisions of this document as it becomes available.
Absolute maximum ratings for the PIC24FJ128GC010 family are listed below. Exposure to these maximum rating
conditions for extended periods may affect device reliability. Functional operation of the device at these, or any other
conditions above the parameters indicated in the operation listings of this specification, is not implied.
Absolute Maximum Ratings(†)
Ambient temperature under bias.............................................................................................................-40°C to +100°C
Storage temperature .............................................................................................................................. -65°C to +150°C
Voltage on VDD with respect to VSS ......................................................................................................... -0.3V to +4.0V
Voltage on any general purpose digital or analog pin (not 5.5V tolerant) with respect to VSS ....... -0.3V to (VDD + 0.3V)
Voltage on any general purpose digital or analog pin (5.5V tolerant, including MCLR) with respect to VSS:
When VDD = 0V: ......................................................................................................................... -0.3V to + 4.0V
When VDD 2.0V: ....................................................................................................................... -0.3V to +6.0V
Voltage on AVDD and SVDD with respect to VSS ..................................(VDD – 0.3V) to (lesser of: 4.0V or (VDD + 0.3V))
Voltage on AVSS and SVSS with respect to VSS ........................................................................................ -0.3V to +0.3V
Voltage on CH0+, CH0-, CH1+ and CH1- with respect to SVSS ................................................. -0.3V to (SVDD + 0.3V)
Voltage on VBAT with respect to VSS ........................................................................................................ . -0.3V to +4.0V
Voltage on VUSB3V3 with respect to VSS ..................................................................................... (VCAP – 0.3V) to +4.0V
Voltage on VBUS with respect to VSS ....................................................................................................... -0.3V to +6.0V
Voltage on D+ or D- with respect to VSS:
(0 source impedance) (Note 1) ..............................................................................-0.5V to (VUSB3V3 + 0.5V)
(source impedance 28, VUSB3V3 3.0V) ............................................................................... -1.0V to +4.6V
Maximum current out of VSS pin ...........................................................................................................................300 mA
Maximum current into VDD pin (Note 2)................................................................................................................250 mA
Maximum output current sunk by any I/O pin..........................................................................................................25 mA
Maximum output current sourced by any I/O pin ....................................................................................................25 mA
Maximum current sunk by all ports .......................................................................................................................200 mA
Maximum current sourced by all ports (Note 2)....................................................................................................200 mA
Note 1:
2:
The original “USB 2.0 Specification” indicated that USB devices should withstand 24-hour short circuits of
D+ or D- to VBUS voltages. This requirement was later removed in an Engineering Change Notice (ECN)
supplement to the USB specifications, which supersedes the original specifications. PIC24FJ128GC010
family devices will typically be able to survive this short-circuit test, but it is recommended to adhere to the
absolute maximum specified here to avoid damaging the device.
Maximum allowable current is a function of device maximum power dissipation (see Table 37-1).
† NOTICE: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at those or any other conditions above
those indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions
for extended periods may affect device reliability.

This is the limit to which VDD may be lowered and the RAM contents will always be retained.
If the VPOR or SRVDD parameters are not met, or the application experiences slow power-down VDD ramp
rates, it is recommended to enable and use the BOR.
On a rising VDD power-up sequence, application firmware execution begins at the higher of the VPORREL or
VBOR level (when BOREN = 1).
