The RPn pins can be used by remappable peripherals. See Table 1 for the available peripherals and 13.3 “Peripheral Pin Select (PPS)”
for restrictions.
Every I/O port pin (RAx-RGx) can be used as a change notification pin (CNAx-CNGx). See 13.0 “I/O Ports” for more information.
Shaded pins are 5V tolerant.
Functions are restricted to input functions only and inputs will be slower than standard inputs.
The I2C library is available in MPLAB Harmony. For future hardware or silicon compatibility, it is recommended to use these pins for the
I2C master/slave clock, that is, SCL.
The I2C library is available in MPLAB Harmony. For future hardware or silicon compatibility, it is recommended to use these pins for the
I2C data I/O, that is, SDA.

GUIDELINES FOR GETTING
STARTED WITH 32-BIT MCUS
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to the
documents listed in the Documentation >
Reference Manual section of the Microchip PIC32 web site (www.microchip.com/
pic32).
Basic Connection Requirements
Getting started with the PIC32MK GP/MC family of 32bit Microcontrollers (MCUs) requires attention to a
minimal set of device pin connections before
proceeding with development. The following is a list of
pin names, which must always be connected:
• All VDD and VSS pins (see 2.2 “Decoupling
Capacitors”)
• All AVDD and AVSS pins, even if the ADC module is
not used (see 2.2 “Decoupling Capacitors”)
• MCLR pin (see 2.3 “Master Clear (MCLR) Pin”)
• PGECx/PGEDx pins, used for In-Circuit Serial
Programming™ (ICSP™) and debugging purposes
(see 2.4 “ICSP Pins”)
• OSC1 and OSC2 pins, when external oscillator
source is used (see 2.7 “External Oscillator Pins”)
The following pins may be required:
VREF+/VREF- pins, used when external voltage
reference for the ADC module is implemented.
Note:
The AVDD and AVSS pins must be
connected, regardless of ADC use and
the ADC voltage reference source.
2016-2019 Microchip Technology Inc.
2.2
Decoupling Capacitors
The use of decoupling capacitors on power supply
pins, such as VDD, VSS, AVDD and AVSS is required.
See Figure 2-1.
Consider the following criteria when using decoupling
capacitors:
• Value and type of capacitor: A value of 0.1 µF
(100 nF), 10-20V is recommended. The capacitor
should be a low Equivalent Series Resistance
(low-ESR) capacitor and have resonance frequency in the range of 20 MHz and higher. It is
further recommended that ceramic capacitors be
used.
• Placement on the printed circuit board: The
decoupling capacitors should be placed as close
to the pins as possible. It is recommended that
the capacitors be placed 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 within onequarter inch (6 mm) in length.
• 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 µF to 0.001 µF. Place this
second capacitor next to the primary decoupling
capacitor. In high-speed circuit designs, consider
implementing a decade pair of capacitances as
close to the power and ground pins as possible.
For example, 0.1 µF in parallel with 0.001 µF.
• 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 track inductance.

• Device Reset
• Device programming and debugging
Pulling The MCLR pin low generates a device Reset.
Figure 2-2 illustrates a typical MCLR circuit. During
device 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 R and C will need to be adjusted based on the
application and PCB requirements.
For example, as illustrated in Figure 2-2, it is
recommended that the capacitor C, be isolated from
the MCLR pin during programming and debugging
operations.

Place the components illustrated in Figure 2-2 within
one-quarter inch (6 mm) from the MCLR pin.

This pin must be connected to VDD, regardless of
whether the USB module is or is not used.
FIGURE 2-2:
2:
As an option, instead of a hard-wired connection, an
inductor (L1) can be substituted between VDD and
AVDD to improve ADC noise rejection. The inductor
impedance should be less than 3 and the inductor
capacity greater than 10 mA.

to 47 µF. This capacitor should be located as close to
the device as possible.

2.4
ICSP Pins
The PGECx and PGEDx pins are used for 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 100 Ohms.
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 input voltage high
(VIH) and input low (VIL) requirements.
Ensure that the “Communication Channel Select” (i.e.,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® ICD 3 or MPLAB REAL ICE™.
For additional information on ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip web
site.

2.6
Trace
When present on select pin counts, the trace pins
can be connected to a hardware trace-enabled programmer to provide a compressed real-time instruction trace. When used for trace, the TRD3, TRD2,
TRD1, TRD0 and TRCLK pins should be dedicated
for this use. The trace hardware requires a 22 Ohm
series resistor between the trace pins and the trace
connector.
2.7
External Oscillator Pins
Many MCUs 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. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. 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 them
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. A suggested layout is illustrated in Figure 2-3.

JTAG
The TMS, TDO, TDI and TCK pins are used for testing
and debugging according to the Joint Test Action
Group (JTAG) standard. It is recommended to keep the
trace length between the JTAG connector and the

JTAG 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 100
Ohms.

Assuming C1 = C2 and PIC32 Cin = Cout, the formula can be further
simplified and restated to solve for C1 and C2 by:
C1 = C2 = ((2 * MFG Cload spec) - Cin - (2 * PCB capacitance))
= ((2 * 15) - 4 - (2 * 2.5 pF))

Therefore:
C1 = C2 = 21 pF is the correct loading capacitors to use on your crystal circuit design to guarantee that the effective capacitance as seen
by the crystal in circuit in this example is 15 pF to meet the crystal
manufacturer specification.
OSC2
Circuit C
Not Recommended
Tips to increase oscillator gain, (i.e., to increase peakto-peak oscillator signal):
• Select an crystal oscillator with a lower XTAL
manufacturing “ESR” rating.
• Add a parallel resistor across the crystal. The greater
the resistor value the greater the gain.
• C1 and C2 values also affect the gain of the oscillator.
The lower the values, the higher the gain.
• Likewise, C2/C1 ratio also affects gain. To increase
the gain, make C1 slightly smaller than C2, which will
also help start-up performance.
Note:
Do not add excessive gain such that the
oscillator signal is clipped, flat on top of
the sine wave. If so, you need to reduce
the gain or add a series resistor, RS, as
shown in circuit “A” in Figure 2-4. Failure
to do so will stress and age the crystal,
which can result in an early failure. When
measuring the oscillator signal you must
use an active-powered scope probe with
1 pF or the scope probe itself will unduly
change the gain and peak-to-peak levels.

Unused I/O pins should not be allowed to float as

to a logic-low state.
2.9.1
Note:
NON-5V TOLERANT INPUT PINS
A quick review of the absolute maximum rating section
in 36.0 “Electrical Characteristics” will indicate that
the voltage on any non-5v tolerant pin may not exceed
VDD + 0.3V unless the input current is limited to meet
the respective injection current specifications defined
by parameters DI60a, DI60b, and DI60c in Table 3610: “DC Characteristics: I/O Pin Input Injection current Specifications”. Figure 2-5 shows an example of
a remote circuit using an independent power source,
which is powered while connected to a PIC32 non-5V
tolerant circuit that is not powered.
Alternatively, inputs can be reserved by connecting the
pin to VSS through a 1k resistor and configuring the pin
as an input.

Without proper signal isolation, on non-5V tolerant
pins, the remote signal can actually power the PIC32
device through the high side ESD protection diodes.
Besides violating the absolute maximum rating
specification when VDD of the PIC32 device is
restored and ramping up or ramping down, it can
also negatively affect the internal Power-on Reset
(POR) and Brown-out Reset (BOR) circuits, which
can lead to improper initialization of internal PIC32
logic circuits. In these cases, it is recommended to
implement digital or analog signal isolation as
depicted in Figure 2-6, as appropriate. This is
indicative of all industry microcontrollers and not just
Microchip products.

5V TOLERANT INPUT PINS
The internal high side diode on 5v tolerant pins are
bussed to an internal floating node, rather than being
connected to VDD, as shown in Figure 2-7. Voltages
on these pins, if VDD < 2.3V, should not exceed
roughly 3.2V relative to VSS of the PIC32 device.
Voltage of 3.6V or higher will violate the absolute
maximum specification, and will stress the oxide
layer separating the high side floating node, which
impacts device reliability. If a remotely powered
“digital-only” signal can be guaranteed to always be
3.2V relative to Vss on the PIC32 device side, a
5V tolerant pin could be used without the need for a
digital isolator. This is assuming there is not a
ground loop issue, logic ground of the two circuits
not at the same absolute level, and a remote logic
low input is not less than VSS - 0.3V.

Designing for High-Speed
Peripherals
The PIC32MK GP/MC family devices have peripherals
that operate at frequencies much higher than typical for
an embedded environment. Table 2-2 lists the peripherals that produce high-speed signals on their external
pins:

Due to these high-speed signals, it is important to
consider several factors when designing a product that
uses these peripherals, as well as the PCB on which
these components will be placed. Adhering to these
recommendations will help achieve the following goals:
• Minimize the effects of electromagnetic interference
to the proper operation of the product
• Ensure signals arrive at their intended destination at
the same time
• Minimize crosstalk
• Maintain signal integrity
• Reduce system noise
• Minimize ground bounce and power sag
2.10.1
2.10.1.1
SYSTEM DESIGN
Impedance Matching
When selecting parts to place on high-speed buses,
particularly the SPI bus and/or REFCLKx output(s), if
the impedance of the peripheral device does not match
the impedance of the pins on the PIC32MK GP/MC
device to which it is connected, signal reflections could
result, thereby degrading the quality of the signal.
If it is not possible to select a product that matches
impedance, place a series resistor at the load to create
the matching impedance. See Figure 2-8 for an
example.
FIGURE 2-8:
SERIES RESISTOR
PIC32MK

2.10.1.2
• Component Placement
- Place bypass capacitors as close to their
component power and ground pins as possible,
and place them on the same side of the PCB
- Devices on the same bus that have larger setup
times should be placed closer to the PIC32MK
GP/MC device
• Power and Ground
- Multi-layer PCBs will allow separate power and
ground planes
- Each ground pin should be connected to the
ground plane individually
- Place bypass capacitor vias as close to the pad
as possible (preferably inside the pad)
- If power and ground planes are not used,
maximize width for power and ground traces
- Use low-ESR, surface-mount bypass capacitors
• Clocks and Oscillators
- Place crystals as close as possible to the
PIC32MK GP/MC device OSC/SOSC pins
- Do not route high-speed signals near the clock or
oscillator
- Avoid via usage and branches in clock lines
(SCK)
- Place termination resistors at the end of clock
lines
• Traces
- Higher-priority signals should have the shortest
traces
- Avoid long run lengths on parallel traces to reduce
coupling
- Make the clock traces as straight as possible
- Use rounded turns rather than right-angle turns
- Have traces on different layers intersect on right
angles to minimize crosstalk
- Maximize the distance between traces, preferably
no less than three times the trace width
- Power traces should be as short and as wide as
possible
- High-speed traces should be placed close to the
ground plane

EMI/EMC/EFT (IEC 61000-4-4 and
IEC 61000-4-2) Suppression
Considerations
The use of LDO regulators is preferred to reduce
overall system noise and provide a cleaner power
source. However, when utilizing switching Buck/Boost
regulators as the local power source for PIC32MK GP
devices, as well as in electrically noisy environments or
test conditions required for IEC 61000-4-4 and IEC
61000-4-2, users should evaluate the use of T-Filters
(i.e., L-C-L) on the power pins, as shown in Figure 2-9.
In addition to a more stable power source, use of this
type of T-Filter can greatly reduce susceptibility to EMI
sources and events.

3.1.2
MULTIPLY/DIVIDE UNIT (MDU)
The processor core includes a Multiply/Divide Unit
(MDU) that contains a separate pipeline for multiply
and divide operations, and DSP ASE multiply instructions. This pipeline operates in parallel with the Integer
Unit (IU) pipeline and does not stall when the IU pipeline stalls. This allows MDU operations to be partially
masked by system stalls and/or other integer unit
instructions.
EXECUTION UNIT
The processor core execution unit implements a load/
store architecture with single-cycle ALU operations
(logical, shift, add, subtract) and an autonomous multiply/divide unit. The core contains thirty-two 32-bit General Purpose Registers (GPRs) used for integer
operations and address calculation. One additional
register file shadow sets (containing thirty-two registers) are added to minimize context switching overhead
during interrupt/exception processing. The register file
consists of two read ports and one write port and is fully
bypassed to minimize operation latency in the pipeline.
The execution unit includes:
• 32-bit adder used for calculating the data address
• Address unit for calculating the next instruction
address
• Logic for branch determination and branch target
address calculation
• Load aligner
• Trap condition comparator
• Bypass multiplexers used to avoid stalls when
executing instruction streams where data
producing instructions are followed closely by
consumers of their results
TABLE 3-1:
• Leading Zero/One detect unit for implementing
the CLZ and CLO instructions
• Arithmetic Logic Unit (ALU) for performing arithmetic
and bitwise logical operations
• Shifter and store aligner
• DSP ALU and logic block for performing DSP
instructions, such as arithmetic/shift/compare
operations
The high-performance MDU consists of a 32x16 Booth
recoded multiplier, a pair of result/accumulation registers (HI and LO), a divide state machine, and the necessary multiplexers and control logic. The first number
shown (‘32’ of 32x16) represents the rs operand. The
second number ‘16’ of 32x16) represents the rt
operand.
The MDU supports execution of one multiply or
multiply-accumulate operation every clock cycle.
Divide operations are implemented with a simple 1-bitper-clock iterative algorithm. An early-in detection
checks the sign extension of the dividend (rs) operand. If rs is 8 bits wide, 23 iterations are skipped. For
a 16-bit wide rs, 15 iterations are skipped and for a
24-bit wide rs, 7 iterations are skipped. Any attempt to
issue a subsequent MDU instruction while a divide is
still active causes an IU pipeline stall until the divide
operation has completed.
Table 3-1 lists the repeat rate (peak issue rate of cycles
until the operation can be reissued) and latency (number of cycles until a result is available) for the processor
core multiply and divide instructions. The approximate
latency and repeat rates are listed in terms of pipeline
clocks.

PIC32MK GP/MC Family
The MIPS architecture defines that the result of a
multiply or divide operation be placed in one of four
pairs of HI and LO registers. Using the Move-From-HI
(MFHI) and Move-From-LO (MFLO) instructions, these
values can be transferred to the General Purpose
Register file.
In addition to the HI/LO targeted operations, the
MIPS32 architecture also defines a multiply instruction, MUL, which places the least significant results in
the primary register file instead of the HI/LO register
pair. By avoiding the explicit MFLO instruction
required when using the LO register, and by supporting multiple destination registers, the throughput of
multiply-intensive operations is increased.
Two other instructions, Multiply-Add (MADD) and
Multiply-Subtract (MSUB), are used to perform the
multiply-accumulate and multiply-subtract operations.
The MADD instruction multiplies two numbers and then
adds the product to the current contents of the HI and
LO registers. Similarly, the MSUB instruction multiplies
two operands and then subtracts the product from the
HI and LO registers. The MADD and MSUB operations
are commonly used in DSP algorithms.
The MDU also implements various shift instructions
operating on the HI/LO register and multiply instructions as defined in the DSP ASE. The MDU supports all
of the data types required for this purpose and includes
three extra HI/LO registers as defined by the ASE.

3.1.4
FLOATING POINT UNIT (FPU)
The Floating Point Unit (FPU), Coprocessor (CP1),
implements the MIPS Instruction Set Architecture for
floating point computation. The implementation supports the ANSI/IEEE Standard 754 (IEEE for Binary
Floating Point Arithmetic) for single- and double-precision data formats. The FPU can be programmed to
have thirty-two 32-bit or 64-bit floating point registers
used for floating point operations.
The performance is optimized for single precision formats. Most instructions have one FPU cycle throughput
and four FPU cycle latency. The FPU implements the
multiply-add (MADD) and multiply-sub (MSUB) instructions with intermediate rounding after the multiply function. The result is guaranteed to be the same as
executing a MUL and an ADD instruction separately,
but the instruction latency, instruction fetch, dispatch
bandwidth, and the total number of register accesses
are improved.
IEEE denormalized input operands and results are
supported by hardware for some instructions. IEEE
denormalized results are not supported by hardware in
general, but a fast flush-to-zero mode is provided to
optimize performance. The fast flush-to-zero mode is
enabled through the FCCR register, and use of this
mode is recommended for best performance when
denormalized results are generated.
The FPU has a separate pipeline for floating point
instruction execution. This pipeline operates in parallel
with the integer core pipeline and does not stall when
the integer pipeline stalls. This allows long-running
FPU operations, such as divide or square root, to be
partially masked by system stalls and/or other integer
unit instructions. Arithmetic instructions are always
dispatched and completed in order, but loads and
stores can complete out of order. The exception model
is “precise” at all times.
Table 3-4 contains the floating point instruction latencies and repeat rates for the processor core. In this
table, 'Latency' refers to the number of FPU cycles necessary for the first instruction to produce the result
needed by the second instruction. The “Repeat Rate”
refers to the maximum rate at which an instruction can
be executed per FPU cycle.

The FPU implements a high-performance 7-stage
pipeline:
• Decode, register read and unpack (FR stage)
• Multiply tree - double pumped for double (M1
stage)
• Multiply complete (M2 stage)
• Addition first step (A1 stage)
• Addition second and final step (A2 stage)
• Packing to IEEE format (FP stage)
• Register writeback (FW stage)
The FPU implements a bypass mechanism that allows
the result of an operation to be forwarded directly to the
instruction that needs it without having to write the
result to the FPU register and then read it back.

3.2
Power Management
The processor core offers a number of power management features, including low-power design, active power
management and power-down modes of operation. The
core is a static design that supports slowing or halting
the clocks, which reduces system power consumption
during Idle periods.
3.2.1
INSTRUCTION-CONTROLLED
POWER MANAGEMENT
The mechanism for invoking Power-Down mode is
through execution of the WAIT instruction. For more
information on power management, see 32.0 “PowerSaving Features”.
3.2.2
LOCAL CLOCK GATING
The majority of the power consumed by the processor
core is in the clock tree and clocking registers. The
PIC32MK family makes extensive use of local gatedclocks to reduce this dynamic power consumption.
3.3
EJTAG Debug Support
The processor core provides for an Enhanced JTAG
(EJTAG) interface for use in the software debug of
application and kernel code. In addition to standard
User mode and Kernel modes of operation, the processor core provides a Debug mode that is entered after a
debug exception (derived from a hardware breakpoint,
single-step exception, etc.) is taken and continues until
a Debug Exception Return (DERET) instruction is
executed. During this time, the processor executes the
debug exception handler routine.
The EJTAG interface operates through the Test Access
Port (TAP), a serial communication port used for transferring test data in and out of the core. In addition to the
standard JTAG instructions, special instructions
defined in the EJTAG specification specify which
registers are selected and how they are used.

MIPS DSP ASE Extension
The MIPS DSP Application-Specific Extension
Revision 2 is an extension to the MIPS32 architecture.
This extension comprises new integer instructions and
states that include new HI/LO accumulator register
pairs and a DSP control register. This extension is
crucial in a wide range of DSP, multimedia, and DSPlike algorithms covering Audio and Video processing
applications. The extension supports native fractional
format data type operations, register Single Instruction
Multiple Data (SIMD) operations, such as add,
subtract, multiply, and shift. In addition, the extension
includes the following features that are essential in
making DSP algorithms computationally efficient:
•
•
•
•
Support for multiplication of complex operands
Variable bit insertion and extraction
Implementation and use of virtual circular buffers
Arithmetic saturation and overflow handling
support
• Zero cycle overhead saturation and rounding
operations
DS60001402G-page 56
3.5
microMIPS ISA
The processor core supports the microMIPS ISA,
which contains all MIPS32 ISA instructions (except for
branch-likely instructions) in a new 32-bit encoding
scheme, with some of the commonly used instructions
also available in 16-bit encoded format. This ISA
improves code density through the additional 16-bit
instructions while maintaining a performance similar to
MIPS32 mode. In microMIPS mode, 16-bit or 32-bit
instructions will be fetched and recoded to legacy
MIPS32 instruction opcodes in the pipeline’s I stage, so
that the processor core can have the same microAptiv
MPU microarchitecture. Because the microMIPS
instruction stream can be intermixed with 16-bit halfword or 32-bit word size instructions on halfword or
word boundaries, additional logic is in place to address
the word misalignment issues, thus minimizing
performance loss.

of devices. It is not intended to be a
comprehensive reference source. For
detailed information, refer to Section 48.
“Memory
Organization
and
Permissions” (DS60001214), which is
available from the Documentation >
Reference Manual section of the
Microchip
PIC32
web
site
(www.microchip.com/pic32).
PIC32MK GP/MC microcontrollers provide 4 GB of
unified virtual memory address space. All memory
regions, including program, data memory, Special
Function Registers (SFRs) and Configuration registers,
reside in this address space at their respective unique
addresses. The program and data memories can be
optionally partitioned into user and kernel memories. In
addition, PIC32MK GP/MC devices allow execution
from data memory.
4.1
Memory Layout
PIC32MK GP/MC microcontrollers implement two address schemes: virtual and physical. All hardware resources, such as program memory, data memory and
peripherals, are located at their respective physical addresses. Virtual addresses are exclusively used by the
CPU to fetch and execute instructions as well as access peripherals. Physical addresses are used by bus
master peripherals, such as DMA and the Flash controller, that access memory independently of the CPU.
The main memory maps for the PIC32MK GP/MC devices are illustrated in Figure 4-1 through Figure 4-2.
Figure 4-3 provides memory map information for boot
Flash and boot alias. Table 4-3 provides memory map
information for SFRs.
Key features of this module include:
• 32-bit native data width
• Separate User (KUSEG) and Kernel (KSEG0/
KSEG1) mode address space
• Separate boot Flash memory for protected code
• Robust bus exception handling to intercept
runaway code
• Read/write permission access to predefined
memory regions

4.1.1
BOOT FLASH SEQUENCE AND
CONFIGURATION SPACES
Sequence space is used to identify which boot Flash is
aliased by aliased regions. If the value programmed
into the TSEQ bits of the BF1SEQ word is equal
to or greater than the value programmed into the
TSEQ bits of the BF2SEQ word, Boot Flash 1 is
aliased by the lower boot alias region, and Boot Flash
2 is aliased by the upper boot alias region. If the
TSEQ bits of the BF2SEQ word is greater than
the TSEQ bits of the BF1SEQ word, the
opposite is true (see Table 4-2 and Table 4-3 for
BFxSEQ word memory locations).
Once boot Flash memories are aliased, configuration
space located in the lower boot alias region is used as
the basis for the Configuration words, DEVSIGN0,
DEVCP0, and DEVCFGx. This means that the boot
Flash region to be aliased by lower boot alias region
memory must contain configuration values in the appropriate memory locations.
Note:
Use only Quad Word program operation
(NVMOP = 0010) when programming data into the sequence and
configuration spaces.

#
As shown in the PIC32MK GP/MC Family Block Diagram (see Figure 1-1), there are multiple initiator modules (I1 through I13) in the system that can access
various target modules (T1 through T14). Table 4-4 illustrates which initiator can access which target. The
System Bus supports simultaneous access to targets
by initiators, so long as the initiators are accessing different targets. The System Bus will perform arbitration,
if multiple initiators attempt to access the same target.

The System Bus arbitration scheme implements a nonprogrammable, Least Recently Serviced (LRS) priority,
which provides Quality Of Service (QOS) for most
initiators. However, some initiators can use Fixed High
Priority (HIGH) arbitration to guarantee their access to
data.
4.3
The arbitration scheme for the available initiators is
shown in Table 4-5.
The System Bus divides the entire memory space into
fourteen target regions and permits access to each
target by initiators through permission groups. Four
Permission Groups (0 through 3) can be assigned to
each initiator. Each permission group is independent
of the others and can have exclusive or shared
access to a region.

Permission Access and System
Bus Registers
The System Bus on PIC32MK GP/MC family of
microcontrollers provides access control capabilities
for the transaction initiators on the System Bus.
Using the CFGPG register (see Register 33-8 in
33.0 “Special Features”), Boot firmware can assign a
permission group to each initiator, which can make
requests on the System Bus.
The available targets and their regions, as well as the
associated control registers to assign protection, are
described and listed in Table 4-6.
Register 4-2 through Register 4-10 are used for setting
and controlling access permission groups and regions.
To change these registers, they must be unlocked in
hardware. The register lock is controlled by the
PGLOCK Configuration bit (CFGCON). Setting
the PGLOCK bit prevents writes to the control registers and clearing the PGLOCK bit allows writes.
To set or clear the PGLOCK bit, an unlock sequence
must be executed. Refer to Section 42. “Oscillators
with Enhanced PLL” (DS60001250) in the “PIC32
Family Reference Manual” for details.

FLASH PROGRAM MEMORY
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 52. “Flash Program Memory
with Support for Live Update”
(DS60001193), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
PIC32MK GP/MC devices contain an internal Flash
program memory for executing user code, which
includes the following features:
• Two Flash banks for live update support
• Dual boot support
• Write protection for program and boot Flash
RTSP is performed by software executing from either
Flash or RAM memory. For information about RTSP
techniques, refer to Section 52. “Flash Program
Memory with Support for Live Update”
(DS60001193) in the “PIC32 Family Reference
Manual”.
EJTAG is performed using the EJTAG port of the
device and an EJTAG capable programmer.
ICSP is performed using a serial data connection to the
device and allows much faster programming times than
RTSP.
The EJTAG and ICSP methods are described in the
“PIC32
Flash
Programming
Specification”
(DS60001145), which is available for download from
the Microchip web site (www.microchip.com).
Note:
In PIC32MK GP/MC devices, the Flash
page size is 1024 Instruction Words and
the row size is 128 Instruction Words.
There are three methods by which the user can
program this memory:
• Run-Time Self-Programming (RTSP)
• EJTAG Programming
• In-Circuit Serial Programming (ICSP)

cold power-up before any attempted
accesses. Refer to Section 58. “Data
EEPROM” (DS60001341) of the “PIC32
Family Reference Manual” for additional
information.
Before any attempts to access the Data
EEPROM module, the user application
must configure the appropriate number of
Wait states by configuring the EEWS
bits (CFGCON2< 7:0>) according to the
details provided in Table 6-1.

This register has corresponding CLR, SET, and INV registers at their virtual addresses, plus offsets of 0x4, 0x8, and 0xC, respectively. See 13.2 “CLR, SET, and INV Registers” for more information.
This register is a write-only register. Reads always result in ‘0’.
Because the EEPROM word size is 32 bits, for reads and writes the last two bits (EEADDR) must always be ‘0’.

Note 1:
2:
The bits in this register cannot be modified when the RW bit (EECON) = 1.
EEDATA is organized in 32-bit words, not by byte, hence the EEADDR bit must always be 32-bit word
address aligned. Check that the EEADDR bits are = 0’b00 at the beginning of any command when
the user sets EEGO to ‘1’. If the EEADDR bits are not 0’b00, it will forcefully clear the EEGO bit to
‘0’ and will also set the ERR bits (EECON) to 0’b10.

and the OSCCON bit will be set. The user software must clear both the bits inside the CF
NMI before attempting to exit the ISR. Software or hardware settings of the CF bit
(OSCCON) will cause a CF NMI event and an automatic clock switch to the FRC provided
the FCKSM = ‘0b11. Unlike the CF bit (OSCCON), software or hardware settings of
the CF bit (RNMICON) will cause a CF NMI event but will not cause a clock switch to the
FRC. After a Clock Fail event, a successful user software clock switch if implemented, hardware
will automatically clear the CF bit (RNMICON), but not the CF bit (OSCCON). The CF
bit (OSCCON) must be cleared by software using the OSCCON register unlock procedure.

CPU EXCEPTIONS AND
INTERRUPT CONTROLLER
This data sheet summarizes the
features of the PIC32MK GP/MC family
of devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 8. “Interrupt
Controller” (DS60001108) and Section
50. “CPU for Devices with MIPS32®
microAptiv™ and M-Class Cores”
(DS60001192), which is available from
the Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
PIC32MK GP/MC devices generate interrupt requests
in response to interrupt events from peripheral modules.
The Interrupt Controller module exists outside of the
CPU and prioritizes the interrupt events before
presenting them to the CPU.
The CPU handles interrupt events as part of the
exception handling mechanism, which is described in
8.1 “CPU Exceptions”.
The Interrupt Controller module includes the following
features:
• Up to 216 interrupt sources and vectors with
dedicated programmable offsets, eliminating the
need for redirection
• Single and multi-vector mode operations
• Five external interrupts with edge polarity control
• Interrupt proximity timer
• Seven user-selectable priority levels for each
vector
• Four user-selectable subpriority levels within each
priority
• Two shadow register sets that can be used for any
priority level, eliminating software context switch and
reducing interrupt latency
• Software can generate any interrupt
Table 8-1 provides Interrupt Service routine (ISR)
latency information.

instruction execution inside ISR).
The CPU ISR latency can cause unexpected behavior in high data rate peripherals when a high repetitive rate of CPU interrupts. For example, it is possible that if multiple interrupt sources occur simultaneously, or if a high-speed peripheral like ADC occurs faster than the CPU can read the results from the first original interrupt, then that data may be overwritten by the second interrupt. If the possibility exists in user application that the CPU servicing requirements are less than the combined sum of all possible overlapping interrupt rate specified above, to avoid buffer overflows or data
overwrites, it is recommended to use the DMA to service the data and buffer instead of the CPU.
For the best optimized CPU and ISR performance, to complete the optimization, the user application should define ISRs that use the “at vector” attribute as shown in Table 8-1. In addition, if the ADC
combined sum throughput rate of all the ADC modules in use is greater than (SYSCLK/43) = 2.8 Msps, it is recommended to use the ADC CPU early interrupt generation defined in the ADCxTIME and
ADCEIENx registers. This will reduce the probability of the ADC results being overwritten by the next conversion before the CPU can read the previous ADC result if not using the DMA for ADC. Do not
use the early interrupts if using the ADC in DMA mode.

Interrupts
The PIC32MK GP/MC family uses variable offsets for
vector spacing. This allows the interrupt vector spacing
to be configured according to application needs. A
unique interrupt vector offset can be set for each vector
using its associated OFFx register.
For details on the Variable Offset feature, refer to
8.5.2 “Variable Offset” in Section 8. “Interrupt
Controller” (DS60001108) of the “PIC32 Family
Reference Manual”.

x = unknown value on Reset; — = unimplemented, read as ‘0’. Reset values are shown in hexadecimal.
Note
All registers in this table with the exception of the OFFx registers, have corresponding CLR, SET, and INV registers at their virtual addresses, plus offsets of 0x4, 0x8, and 0xC, respectively. See 13.2 “CLR, SET, and
INV Registers” for more information.
This bit is not available on 64-pin devices.
This bit is not available on devices without a CAN module.
This bit is not available on 100-pin devices.
Bits 31 and 30 are not available on 64-pin and 100-pin devices; bits 29 through 14 are not available on 64-pin devices.
Bits 31, 30, 29, and bits 5 through 0 are not available on 64-pin and 100-pin devices; bit 22 is not available on 64-pin devices.
The IFSx bits, as with all interrupt flag status register bits, are set as long as the peripheral is enabled and an interrupt condition event occurs. Interrupts do not have to be enabled for the IFSx bits to be set. If the user
application does not want to use an interrupt, it can poll the corresponding peripheral IFSx bit to see whether an interrupt condition has occurred. The IFSx bits are persistent, they must be cleared if they are set by
user software after an IFSx user bit interrogation.

This bit is not available on 64-pin devices.
This bit is not available on devices without a CAN module.
This bit is not available on 100-pin devices.
Bits 31 and 30 are not available on 64-pin and 100-pin devices; bits 29 through 14 are not available on 64-pin devices.
Bits 31, 30, 29, and bits 5 through 0 are not available on 64-pin and 100-pin devices; bit 22 is not available on 64-pin devices.
The IFSx bits, as with all interrupt flag status register bits, are set as long as the peripheral is enabled and an interrupt condition event occurs. Interrupts do not have to be enabled for the IFSx bits to be set. If the user
application does not want to use an interrupt, it can poll the corresponding peripheral IFSx bit to see whether an interrupt condition has occurred. The IFSx bits are persistent, they must be cleared if they are set by
user software after an IFSx user bit interrogation.

Refer to 2.0 “Guidelines for Getting Started with 32-bit MCUs” for recommended external crystal component values and restrictions.
The internal POSC feedback resistor, RF, is typically in the range of 2 to 10 M.
The maximum PBCLK6 clock rate to the peripherals in the VBAT power domain is 30 MHz. This is not the power-up default and must be configured by the user before attempting any access to
those peripherals.
The shaded region indicates peripherals contained and powered from VBAT on devices that support battery operation from the VBAT pin.
Refer to Table 36-16 in 36.0 “Electrical Characteristics” for PBCLK6 frequency limitations.
CLKO on OSC2 pin, if enabled in configuration word, available in EC & FRC mode is PBCLK1 / 2.

9.1
Fail-Safe Clock Monitor (FSCM)
The PIC32MK GP/MC oscillator system includes a Failsafe Clock Monitor (FSCM). The FSCM monitors the
SYSCLK for continuous operation. If it detects that the
SYSCLK has failed, it switches the SYSCLK over to the
FRC oscillator and triggers a NMI. When the NMI is
executed, software can attempt to restart the main
oscillator or shut down the system.
In Sleep mode, both the SYSCLK and the FSCM halt,
which prevents FSCM detection.

the FCKSM = ‘0b11. Unlike the CF bit (OSCCON), software or hardware settings of
the CF bit (RNMICON) will cause a CF NMI event but will not cause a clock switch to the
FRC. After a Clock Fail event, a successful user software clock switch if implemented, hardware

Writes to this register are not allowed if the SPLL is selected as a clock source (COSC = 001).
While the PLL is active, and if updating the PLL bits in the OSCCON register at run-time, the user application must remain within the following limits at all times for all nodes in the PLL clock tree. Therefore, the
order in which the PLL values may be modified, (i.e., PLLODIV, PLLMULT, PLLODIV) becomes important.
Failure to maintain PLL nodes within min/max ranges may result in unstable PLL and system behavior.

While the ON bit (REFOxCON) is ‘1’, writes to this register do not take effect until the DIVSWEN bit is
also set to ‘1’.
Do not write to this register when the ON bit (REFOxCON) is not equal to the ACTIVE bit
(REFOxCON).
Specified values in this register do not take effect if RODIV (REFOxCON) = 0.
REFCLKOx Frequency = ((Selected Source Clock / 2) * (N + (M / 512)))
where, Selected source clock = ROSEL, N = RODIV, and M = ROTRIM.
If the value of REFCLKOx Frequency is not a whole integer value, the output clock will have jitter as it will
cause the REFCLKOx circuit to clock cycle steal to produce an average frequency equivalent to the user
application’s desired frequency. The amount of jitter, (i.e., clock cycle steals), become less as the
fractional remainder value becomes closer to a whole number and is greatest at any value plus 0.5.

Note:
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 4. “Prefetch Cache Module”
(DS60001119), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The Prefetch module is a performance enhancing
module that is included in the PIC32MK GP/MC family
of devices. When running at high-clock rates, Wait
states must be inserted into Program Flash Memory
(PFM) read transactions to meet the access time of the
PFM. Wait states can be hidden to the core by
prefetching and storing instructions in a temporary
holding area that the CPU can access quickly. Although
the data path to the CPU is 32 bits wide, the data path
to the PFM is 128 bits wide. This wide data path
provides the same bandwidth to the CPU as a 32-bit
path running at four times the frequency.
FIGURE 10-1:
The Prefetch module holds a subset of PFM in
temporary holding spaces known as lines. Each line
contains a tag and data field. Normally, the lines hold a
copy of what is currently in memory to make
instructions or data available to the CPU without Flash
Wait states.

DIRECT MEMORY ACCESS
(DMA) CONTROLLER
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 31. “Direct Memory Access
(DMA) Controller” (DS60001117), which
is available from the Documentation >
Reference Manual section of the
Microchip
PIC32
web
site
(www.microchip.com/pic32).
The Direct Memory Access (DMA) Controller is a bus
master module useful for data transfers between
different devices without CPU intervention. The source
and destination of a DMA transfer can be any of the
memory mapped modules existent in the device such
as SPI, UART, PMP, etc., or memory itself.
Following are some of the key features of the DMA
Controller module:
• Eight identical channels, each featuring:
- Auto-increment source and destination
address registers
- Source and destination pointers
- Memory-to-memory and memory-toperipheral transfers
• Automatic word-size detection:
- Transfer granularity, down to byte level
- Bytes need not be word-aligned at source and
destination
FIGURE 11-1:
INT Controller
Peripheral Bus
• Fixed priority channel arbitration
• Flexible DMA channel operating modes:
- Manual (software) or automatic (interrupt) DMA
requests
- One-Shot or Auto-Repeat Block Transfer modes
- Channel-to-channel chaining
• Flexible DMA requests:
- A DMA request can be selected from any of the
peripheral interrupt sources
- Each channel can select any (appropriate)
observable interrupt as its DMA request source
- A DMA transfer abort can be selected from any
of the peripheral interrupt sources
- Up to 2-byte Pattern (data) match transfer
termination
• Multiple DMA channel status interrupts:
- DMA channel block transfer complete
- Source empty or half empty
- Destination full or half full
- DMA transfer aborted due to an external event
- Invalid DMA address generated
• DMA debug support features:
- Most recent error address accessed by a DMA
channel
- Most recent DMA channel to transfer data
• CRC Generation module:
- CRC module can be assigned to any of the
available channels
- CRC module is highly configurable

Writing to this register will seed the CRC generator. Reading from this register will return the current value of
the CRC. Bits greater than PLEN will return ‘0’ on any read.
When CRCTYP (DCRCCON) = 1 (CRC module is in IP Header mode):
Only the lower 16 bits contain IP header checksum information. The upper 16 bits are always ‘0’. Data written
to this register is converted and read back in 1’s complement form (i.e., current IP header checksum value).
When CRCTYP (DCRCCON) = 0 (CRC module is in LFSR mode):
Bits greater than PLEN will return ‘0’ on any read.

full-speed and low-speed embedded host, full-speed
device or OTG implementation with a minimum of
external components. This module in Host mode is
intended for use as an embedded host and therefore
does not implement a UHCI or OHCI controller.
The USB module consists of the clock generator, the
USB voltage comparators, the transceiver, the Serial
Interface Engine (SIE), a dedicated USB DMA controller, pull-up and pull-down resistors, and the register
interface. A block diagram of the PIC32MK USB OTG
module is presented in Figure 12-1.
The PIC32MK USB module includes the following
features:
•
•
•
•
•
•
•
•
•
USB full-speed support for host and device
Low-speed host support
USB OTG support
Integrated signaling resistors
Integrated analog comparators for VBUS
monitoring
Integrated USB transceiver
Transaction handshaking performed by hardware
Endpoint buffering anywhere in system RAM
Integrated DMA to access system RAM and Flash
Note:
The implementation and use of the USB
specifications, and other third party
specifications or technologies, may
require licensing; including, but not limited
to, USB Implementers Forum, Inc. (also
referred to as USB-IF). The user is fully
responsible
for
investigating
and
satisfying any applicable licensing
obligations.
The clock generator provides the 48 MHz clock
required for USB full-speed and low-speed communication. The voltage comparators monitor the voltage on
the VBUS pin to determine the state of the bus. The
transceiver provides the analog translation between
the USB bus and the digital logic. The SIE is a state
machine that transfers data to and from the endpoint
buffers and generates the hardware protocol for data
transfers. The USB DMA controller transfers data
between the data buffers in RAM and the SIE. The integrated pull-up and pull-down resistors eliminate the
need for external signaling components. The register
interface allows the CPU to configure and
communicate with the module.

These bits are contained in the DEVCFG2 register.
A 48 MHz clock is required for proper USB operation.
Pins can be used as GPIO when the USB module is disabled or when the USB module is enabled but the
FVBUSIOx bit (DEVCFG3) = 0 or the FUSBIDIOx bit (DEVCFG3) = 0.

Software is required to check this bit before issuing another token command to the UxTOK register (see
Register 12-15).
All host control logic is reset any time that the value of this bit is toggled.
Software must set the RESUME bit for 10 ms if the part is a function, or for 25 ms if the part is a host, and
then clear it to enable remote wake-up. In Host mode, the USB module will append a low-speed EOP to
the RESUME signaling when this bit is cleared.

Software is required to check this bit before issuing another token command to the UxTOK register (see
Register 12-15).
All host control logic is reset any time that the value of this bit is toggled.
Software must set the RESUME bit for 10 ms if the part is a function, or for 25 ms if the part is a host, and
then clear it to enable remote wake-up. In Host mode, the USB module will append a low-speed EOP to
the RESUME signaling when this bit is cleared.

I/O PORTS
Note:
with alternate function(s). These functions depend on
which peripheral features are on the device. In general,
when a peripheral is functioning, that pin may not be
used as a general purpose I/O pin.
This data sheet summarizes the features
of the PIC32MK GP/MC Family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 12. “I/O Ports”
(DS60001120), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The following are key features of the I/O ports:
• Individual output pin open-drain enable/disable
• Individual input pin weak pull-up and pull-down
• Monitor selective inputs and generate interrupt
when change in pin state is detected
• Operation during Sleep mode and Idle mode
• Fast bit manipulation using CLR, SET, and INV
registers
Figure 13-1 illustrates a block diagram of a typical
multiplexed I/O port.
General purpose I/O pins are the simplest of
peripherals. They allow the PIC32MK GP/MC family
device to monitor and control other devices. To add
flexibility and functionality, some pins are multiplexed

13.1
Parallel I/O (PIO) Ports
All port pins have ten registers directly associated with
their operation as digital I/O. The data direction register
(TRISx) determines whether the pin is an input or an
output. If the data direction bit is a ‘1’, then the pin is an
input. All port pins are defined as inputs after a Reset.
Reads from the latch (LATx) read the latch. Writes to
the latch write the latch. Reads from the port (PORTx)
read the port pins, while writes to the port pins write the
latch.
13.1.1
OPEN-DRAIN CONFIGURATION
In addition to the PORTx, LATx, and TRISx registers for
data control, some port pins can also be individually
configured for either digital or open-drain output. This is
controlled by the Open-Drain Control register, ODCx,
associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain
output.
The open-drain feature allows the generation of outputs
higher than VDD (e.g., 5V) on any desired 5V-tolerant
pins by using external pull-up resistors. The maximum
open-drain voltage allowed is the same as the
maximum VIH specification.
Refer to the pin name tables (Table 3 and Table 5) for
the available pins and their functionality.
13.1.2
CONFIGURING ANALOG AND
DIGITAL PORT PINS
The ANSELx register controls the operation of the
analog port pins. The port pins that are to function as
analog inputs must have their corresponding ANSEL
and TRIS bits set. In order to use port pins for I/O
functionality with digital modules, such as Timers,
UARTs, etc., the corresponding ANSELx bit must be
cleared.
The ANSELx register has a default value of 0xFFFF;
therefore, all pins that share analog functions are
analog (not digital) by default.
If the TRIS bit is cleared (output) while the ANSELx bit
is set, the digital output level (VOH or VOL) is converted
by an analog peripheral, such as the ADC module or
Comparator module.
When the PORT register is read, all pins configured as
analog input channels are read as cleared (a low level).
Pins configured as digital inputs do not convert an
analog input. Analog levels on any pin defined as a
digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.
DS60001402G-page 244
13.1.3
I/O PORT WRITE/READ TIMING
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically this instruction
would be an NOP.
13.1.4
INPUT CHANGE NOTIFICATION
The input change notification function of the I/O ports
allows the PIC32MK GP/MC devices to generate
interrupt requests to the processor in response to a
change-of-state on selected input pins. This feature can
detect input change-of-states even in Sleep mode,
when the clocks are disabled. Every I/O port pin can be
selected (enabled) for generating an interrupt request
on a change-of-state.
Five control registers are associated with the CN functionality of each I/O port. The CNENx and CNNEx registers contain the CN interrupt enable control bits for
each of the input pins. Setting these bits enables a CN
interrupt for the corresponding pins. The CNENx register enables a mismatch CN interrupt condition when
the EDGEDETECT bit (CNCONx) is not set.
When the EDGEDETECT bit is set, the CNNEx register
controls the negative edge while the CNENx register
controls the positive edge.
The CNSTATx and CNFx registers indicate the status
of change notice based on the setting of the
EDGEDETECT bit. If the EDGEDETECT bit is set to
‘0’, the CNSTATx register indicates whether a change
occurred on the corresponding pin since the last read
of the PORTx bit. If the EDGEDETECT bit is set to ‘1’,
the CNFx register indicates whether a change has
occurred and through the CNNEx and CNENx registers
the edge type of the change that occurred is also
indicated.
Each I/O pin also has a weak pull-up and a weak
pull-down connected to it. The pull-ups act as a
current source or sink source connected to the pin,
and eliminate the need for external resistors when
push-button or keypad devices are connected. The
pull-ups and pull-downs are enabled separately using
the CNPUx and the CNPDx registers, which contain
the control bits for each of the pins. Setting any of
the control bits enables the weak pull-ups and/or
pull-downs for the corresponding pins.
Note:
Pull-ups and pull-downs on change
notification pins should always be
disabled when the port pin is configured as
a digital output.
An additional control register (CNCONx) is shown in
Register 13-3.

13.2
CLR, SET, and INV Registers
Every I/O module register has a corresponding CLR
(clear), SET (set) and INV (invert) register designed to
provide fast atomic bit manipulations. As the name of
the register implies, a value written to a SET, CLR or
INV register effectively performs the implied operation,
but only on the corresponding base register and only
bits specified as ‘1’ are modified. Bits specified as ‘0’
are not modified.
Reading SET, CLR and INV registers returns undefined
values. To see the affects of a write operation to a SET,
CLR or INV register, the base register must be read.
13.3
Peripheral Pin Select (PPS)
A major challenge in general purpose devices is providing the largest possible set of peripheral features while
minimizing the conflict of features on I/O pins. The challenge is even greater on low pin-count devices. In an
application where more than one peripheral needs to
be assigned to a single pin, inconvenient workarounds
in application code or a complete redesign may be the
only option.
PPS configuration provides an alternative to these
choices by enabling peripheral set selection and their
placement on a wide range of I/O pins. By increasing
the pinout options available on a particular device,
users can better tailor the device to their entire
application, rather than trimming the application to fit
the device.
The PPS configuration feature operates over a fixed
subset of digital I/O pins. Users may independently
map the input and/or output of most digital peripherals
to these I/O pins. PPS is performed in software and
generally does not require the device to be
reprogrammed. Hardware safeguards are included that
prevent accidental or spurious changes to the peripheral mapping once it has been established.
13.3.1
AVAILABLE PINS
The number of available pins is dependent on the
particular device and its pin count. Pins that support the
PPS feature include the designation “RPn” in their full
pin designation, where “RP” designates a remappable
peripheral and “n” is the remappable port number.
13.3.2
AVAILABLE PERIPHERALS
The peripherals managed by the PPS are all digitalonly peripherals. These include general serial
communications (UART, SPI, and CAN), general purpose timer clock inputs, timer-related peripherals (input
capture and output compare), interrupt-on-change
inputs, and reference clocks (input and output).
In comparison, some digital-only peripheral modules
are never included in the PPS feature. This is because
the peripheral’s function requires special I/O circuitry
on a specific port and cannot be easily connected to
multiple pins. A similar requirement excludes all
modules with analog inputs, such as the Analog-toDigital Converter (ADC).
A key difference between remappable and non-remappable peripherals is that remappable peripherals are
not associated with a default I/O pin. The peripheral
must always be assigned to a specific I/O pin before it
can be used. In contrast, non-remappable peripherals
are always available on a default pin, assuming that the
peripheral is active and not conflicting with another
peripheral.
When a remappable peripheral is active on a given I/O
pin, it takes priority over all other digital I/O and digital
communication peripherals associated with the pin.
Priority is given regardless of the type of peripheral that
is mapped. Remappable peripherals never take priority
over any analog functions associated with the pin.
13.3.3
CONTROLLING PPS
PPS features are controlled through two sets of SFRs:
one to map peripheral inputs, and one to map outputs.
Because they are separately controlled, a particular
peripheral’s input and output (if the peripheral has both)
can be placed on any selectable function pin without
constraint.
The association of a peripheral to a peripheral-selectable pin is handled in two different ways, depending on
whether an input or output is being mapped.
13.3.4
INPUT MAPPING
The inputs of the PPS options are mapped on the basis
of the peripheral. That is, a control register associated
with a peripheral dictates the pin it will be mapped to.
The [pin name]R registers, where [pin name] refers to the
peripheral pins listed in Table 13-1, are used to configure peripheral input mapping (see Register 13-1). Each
register contains sets of 4 bit fields. Programming these
bit fields with an appropriate value maps the RPn pin
with the corresponding value to that peripheral. For any
given device, the valid range of values for any bit field is
shown in Table 13-1.
Figure 13-2 illustrates the remappable pin selection for
the U1RX input.

OUTPUT MAPPING
13.3.6.1
In contrast to inputs, the outputs of the PPS options
are mapped on the basis of the pin. In this case, a
control register associated with a particular pin
dictates the peripheral output to be mapped. The
RPnR registers (Register 13-2) are used to control
output mapping. Like the [pin name]R registers, each
register contains sets of 4 bit fields. The value of the
bit field corresponds to one of the peripherals, and
that peripheral’s output is mapped to the pin (see
Table 13-2 and Figure 13-3).
A null output is associated with the output register reset
value of ‘0’. This is done to ensure that remappable
outputs remain disconnected from all output pins by
default.

Control Register Lock
Under normal operation, writes to the RPnR and [pin
name]R registers are not allowed. Attempted writes
appear to execute normally, but the contents of the
registers remain unchanged. To change these
registers, they must be unlocked in hardware. The
register lock is controlled by the IOLOCK
Configuration bit (CFGCON). Setting the
IOLOCK bit prevents writes to the control registers
and clearing the IOLOCK bit allows writes.
To set or clear the IOLOCK bit, an unlock sequence
must be executed. Refer to the Section 42. “Oscillators with Enhanced PLL” (DS60001250) in the
“PIC32 Family Reference Manual” for details.
13.3.6.2
Configuration Bit Select Lock
As an additional level of safety, the device can be
configured to prevent more than one write session to
the RPnR and [pin name]R registers. The IOL1WAY
Configuration bit (DEVCFG3) blocks the IOLOCK
bit from being cleared after it has been set once. If the
IOLOCK bit remains set, the register unlock procedure
does not execute, and the PPS control registers cannot
be written to. The only way to clear the bit and reenable peripheral remapping is to perform a device
Reset.
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session.

CONTROLLING CONFIGURATION
CHANGES
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. The PIC32MK GP/MC devices include two
features to prevent alterations to the peripheral map:
• Control register lock sequence
• Configuration bit select lock

Note:
TIMER1
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 14. “Timers” (DS60001105),
which is available from the Documentation
> Reference Manual section of the
Microchip
PIC32
web
site
(www.microchip.com/pic32).
PIC32MK GP/MC devices feature one synchronous/
asynchronous 16-bit timer that can operate as a free-running interval timer for various timing applications and
counting external events. This timer can also be used
with the low-power Secondary Oscillator (SOSC) for realtime clock applications.
The following modes are supported by Timer1:
•
•
•
•
Synchronous Internal Timer
Synchronous Internal Gated Timer
Synchronous External Timer
Asynchronous External Timer
14.1
Additional Supported Features
• Selectable clock prescaler
• Timer operation during Sleep and Idle modes
• Fast bit manipulation using CLR, SET, and INV
registers
• Asynchronous mode can be used with the SOSC
to function as a real-time clock
• ADC event trigger
14.2
14.2.1
14.2.2
ASYNCHRONOUS MODE
OPERATION
When writing the ON bit when the Timer is configured
in Asynchronous mode or in an external clock mode
with the prescaler enabled, the act of setting the ON bit
does not take effect until two rising edges of the
external clock input have occurred.
14.2.3
ASYNCHRONOUS MODE
OPERATION WITH A PENDING
TMRx REGISTER WRITE
When the Timer is configured in Asynchronous mode
and the Timer is attempting to write to the TMRx
register while a previous write is awaiting
synchronization, the value written to the timer can
become corrupted.
To ensure that writes will not cause the TMRx value to
become corrupted, the TWDIS bit (TxCON), when
set, will ignore a write to the TMRx register when a
previous write to the TMRx register is awaiting synchronization into the Asynchronous Timer Clock domain.
The TWIP bit (TxCON) indicates when write
synchronization is complete, and it is safe to write
another value to the timer.
14.2.4
PRx REGISTER WRITES
Writing to the PRx register while the Timer is active,
may cause erratic operation.
TImer1 Usage Model Guidelines
EXTERNAL CLOCK MODE
OPERATION
When the Timer is operating with an external clock
mode with the TCS bit (TxCON) = 1, the mode bits
of the TxCON register must be initialized using a separate Write operation from that used to enable the Timer.
Specifically, the TCS, TSYNC, etc. bits must be written
first, and then the ON bit (TxCON) must be set in
a subsequent write.
Once the ON bit is set, any writes to the TxCON
register may cause erroneous counter operation.
Note:
The ON bit should be clear when updates
are made to any other bits in the TxCON
register.

DEADMAN TIMER (DMT)
Note:
The primary function of the Deadman Timer (DMT) is
to reset the processor in the event of a software malfunction. The DMT is a free-running instruction fetch
timer, which is clocked whenever an instruction fetch
occurs until a count match occurs. Instructions are not
fetched when the processor is in Sleep mode.
This data sheet summarizes the
features of the PIC32MK GP/MC family
of devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 9. “Watchdog,
Deadman, and Power-up Timers”
(DS60001114), which is available from
the Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The DMT consists of a 32-bit counter with a time-out
count match value as specified by the DMTCNT
bits in the DEVCFG1 Configuration register.
A Deadman Timer is typically used in mission critical
and safety critical applications, where any single
failure of the software functionality and sequencing
must be detected.
Figure 16-1 shows a block diagram of the Deadman
Timer module.

WATCHDOG TIMER (WDT)
Note:
This data sheet summarizes the features
of the PIC32MK GP/MC Family of
devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 9. “Watchdog,
Deadman, and Power-up Timers”
(DS60001114), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
FIGURE 17-1:
When enabled, the Watchdog Timer (WDT) operates
from the internal Low-Power Oscillator (LPRC) clock
source and can be used to detect system software malfunctions by resetting the device if the WDT is not
cleared periodically in software. Various WDT time-out
periods can be selected using the WDT postscaler. The
WDT can also be used to wake the device from Sleep
or Idle mode.
Some of the key features of the WDT module are as
follows:
• Configuration or software controlled
• User-configurable time-out period
• Can wake the device from Sleep mode or Idle
mode

INPUT CAPTURE
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section
15.
“Input
Capture”
(DS60001122), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The Input Capture module is useful in applications
requiring frequency (period) and pulse measurement.
The Input Capture module captures the 16-bit or 32-bit
value of the selected Time Base registers when an
event occurs at the ICx pin.
Capture events are caused by the following factors:
• Capture timer value on every edge (rising and falling),
specified edge first
• Prescaler capture event modes:
- Capture timer value on every 4th rising edge of
input at ICx pin
- Capture timer value on every 16th rising edge of
input at ICx pin
- Capture every falling edge of input at ICx pin
- Capture every rising edge of input at ICx pin
- Capture every 4th rising edge of input at ICx
pin
- Capture every 16th rising edge of input at ICx
pin
- Capture every rising and falling edge of input
at ICx pin
- Capture timer values based on internal or
external clocks
Each input capture channel can select between either
eight 16-bit time bases or four 32-bit time base. The
selected timer can use either an internal or external
clock.
Other operational features include:
• Device wake-up from capture pin during Sleep and
Idle modes
• Interrupt on input capture event
• 4-word FIFO buffer for capture values; Interrupt
optionally generated after 1, 2, 3, or 4 buffer
locations are filled
• Input capture can also be used to provide additional
sources of external interrupts

Note:
OUTPUT COMPARE
When a match occurs, the Output Compare module
generates an event based on the selected mode of
operation.
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section
16.
“Output
Compare”
(DS60001111), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The following are some of the key features of the
Output Compare:
• Multiple Output Compare modules in a device
• Programmable interrupt generation on compare
event
• Single and Dual Compare modes
• Single and continuous output pulse generation
• Pulse-Width Modulation (PWM) mode
• Hardware-based PWM Fault detection and
automatic output disable
• Programmable selection of 16-bit or 32-bit time
bases
• Can operate from either of two available 16-bit
time bases or a single 32-bit time base
• ADC event trigger for OC1 through OC4
The Output Compare module is used to generate a
single pulse or a train of pulses in response to selected
time base events.
For all modes of operation, the Output Compare module compares the values stored in the OCxR and/or the
OCxRS registers to the value in the selected timer.

controls the OCMP4-OCMP6, OCMP10-OCMP12, and OCMP16 channels.
3: Refer to Table 19-1 for Timerx and Timery selections.
4: The ADC event trigger is only available on OC1 through OC4.
5: PBCLK2 = Output Compare 1 through Output Compare 9; PBCLK3 = Output Compare 10 through Output Compare 16.

The timer source for each Output Compare module
depends on the setting of the OCACLK bit in the
CFGCON register, the OC32 bit in the OCxCON
register, and the OCTSEL bit in the OCxCON register.

- FIFO buffers act as 4/8/16-level deep FIFOs
based on 32/24/16/8-bit data width
• Programmable interrupt event on every 8-bit,
16-bit and 32-bit data transfer
• Operation during Sleep and Idle modes
• Audio codec support:
- I2S protocol
- Left-justified
- Right-justified
- PCM
The SPI/I2S module is a synchronous serial interface
that is useful for communicating with external
peripherals and other microcontroller devices, as well
as digital audio devices. These peripheral devices may
be Serial EEPROMs, Shift registers, display drivers,
analog-to-digital converters (ADC), etc.

Baud Rate = FPBCLKx / (2 * (SPIxBRG + 1)), where x = 2 and 3, (FPBCLK2 for SPI1-SPI2, FPBCLK3
for SPI3-SPI6.) Therefore, the maximum baud rate possible is FPBCLKx / 2 (SPIXBRG = 0) and the
minimum baud rate possible is FPBCLKx / 16384.
Note:
Changing the BRG value when the ON bit is equal to ‘1’ causes undefined behavior.

The I2C software library is available in MPLAB
Harmony. If the user application is to implement I2C, for
future device pin compatibility, it is recommended to
assign software I2C functions according to the details
provided in the device pin tables (Table 3 through
Table 6):
• For 64-pin packages, refer to Notes 6 and 7 in
Table 3 and Table 4.
• For 100-lead packages, refer to Notes 5 and 6 in

UNIVERSAL ASYNCHRONOUS
RECEIVER TRANSMITTER
(UART)
Note:
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 21. “Universal Asynchronous
Receiver
Transmitter
(UART)”
(DS60001107), which is available from the
Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The UART module is one of the serial I/O modules
available in PIC32MK GP/MC family devices. The
UART is a full-duplex, asynchronous communication
channel that communicates with peripheral devices
and personal computers through protocols, such as
RS-232, RS-485, LIN, and IrDA®. The module also
supports the hardware flow control option, with
UxCTS and UxRTS pins, and also includes an IrDA
encoder and decoder.
The following are key features of the UART module:
• Ability to receive data during Sleep mode
• Full-duplex, 8-bit or 9-bit data transmission
• Even, Odd or No Parity options (for 8-bit data)
• One or two Stop bits
• Auto-baud support
• Four clock source inputs for asynchronous clocking
• Transmit and Receive (TX/RX) polarity control
• Hardware flow control option
• Fully integrated Baud Rate Generator (BRG) with
16-bit prescaler
• Baud rates up to 30 Mbps
• 8-level deep First-In-First-Out (FIFO) transmit data
buffer
• 8-level deep FIFO receive data buffer
• Parity, framing and buffer overrun error detection
• Support for interrupt-only on address detect
(9th bit = 1)
• Separate transmit and receive interrupts
• Loopback mode for diagnostic support
• LIN Protocol support
• IrDA encoder and decoder with 16x baud clock
output for external IrDA encoder/decoder support
Figure 22-1 illustrates a simplified block diagram of the
UART module.

UART Broadcast Mode Example
To send a broadcast message to all UARTs in the group
identified by bit 7 = 1, send UxTXREG = (0x190),
address bit 9 set. All the UARTs in that group, bit 7 = 1,
would generate an interrupt for an address match
because of the bit , match, Logic AND of
MASK and ADDR registers equal “true”. User software
would check if bit 4 = 1, and if true, the RX bits
register value is valid for all UARTS.
As shown in Table 22-4, the group hardware address
identifier bit was arbitrarily chosen as bit 7 with bit 4
chosen as the software group or individual UART target
ID. Therefore, the collective group address assigned
for all UARTs (i.e, [w, x, y, z]) is ‘0b100100xx, while
the individual addresses are ‘0b10000000 through
‘0b10000011, respectively.
To send a specific message to UARTy within the group,
the user would send UxTXREG = (0x182), address bit
9 set. All of the UARTs in that group identified with bit 7
= 1 would still generate an interrupt for an address
match because of the bit , address match,
Logic AND of MASK and ADDR registers equal True. In
this case, user software would check if bit 4 = 0, and if
true, the RX bits register value would be intended
only for UARTy, with all others ignored.
Any MASK register bit = 0 means the corresponding
ADDR bit is a “don't care” from a hardware
address matching point of view. Using this scheme,
multiple UART subnet groups could be created within a
network. If not using address match with a broadcast
mode, set the ADDRMSK bits (UxSTAT Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).

This register is used for Read operations in the Enhanced Parallel Slave mode and Write operations for Dual
Buffer Master mode.
In Dual Buffer Master mode, the DUALBUF bit (PMPCON) = 1, a write to the MSB triggers the transaction on the PMP port. When MODE16 = 1, MSB = DATAOUT. When MODE16 = 0,
MSB = DATAOUT.
Note:
In Master mode, a read will return the last value written to the register. In Slave mode, a read will return
indeterminate results.

In Parallel Master mode, a write to the MSB triggers the write transaction on the PMP port. Similarly, a read
to the MSB triggers the read transaction on the PMP port.
When MODE16 = 1, MSB = DATAIN. When MODE16 = 0, MSB = DATAIN.
Note:
This register is not used in Dual Buffer Master mode (i.e., DUALBUF bit (PMPCON) = 1).

REAL-TIME CLOCK AND
CALENDAR (RTCC)
This data sheet summarizes the
features of the PIC32MK GP/MC family
of devices. It is not intended to be a
comprehensive reference source. To
complement the information in this data
sheet, refer to Section 29. “Real-Time
Clock
and
Calendar
(RTCC)”
(DS60001125), which is available from
the Documentation > Reference Manual
section of the Microchip PIC32 web site
(www.microchip.com/pic32).
The RTCC module is intended for applications in which
accurate time must be maintained for extended periods
of time with minimal or no CPU intervention. Lowpower optimization provides extended battery lifetime
while keeping track of time.
The following are key features of the RTCC module:
• Time: hours, minutes and seconds
• 24-hour format (military time)
• Visibility of one-half second period
FIGURE 24-1:
• Provides calendar: Weekday, date, month and year
• Alarm intervals are configurable for half of a second,
one second, 10 seconds, one minute, 10 minutes,
one hour, one day, one week, one month, and one
year
• Alarm repeat with decrementing counter
• Alarm with indefinite repeat: Chime
• Year range: 2000 to 2099
• Leap year correction
• BCD format for smaller firmware overhead
• Optimized for long-term battery operation
• Fractional second synchronization
• User calibration of the clock crystal frequency with
auto-adjust
• Calibration range: 0.66 seconds error per month
• Calibrates up to 260 ppm of crystal error
• Uses external 32.768 kHz crystal or 32 kHz
internal oscillator
• Alarm pulse, seconds clock, or internal clock output
on RTCC pin (not in VBAT power domain, requires
VDD)

This bit is undefined when RTCCLKSEL = 00 (LPRC is the clock source).
Note:
This register is reset only on a POR.

12-BIT HIGH-SPEED
SUCCESSIVE APPROXIMATION
REGISTER (SAR) ANALOG-TODIGITAL CONVERTER (ADC)
This data sheet summarizes the features
of the PIC32MK GP/MC family of devices.
It is not intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section
22.
“12-bit
High-Speed
Successive Approximation Register
(SAR) Analog-to-Digital
Converter
(ADC)” (DS60001344) in the “PIC32
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com/PIC32).
The 12-bit High-Speed Successive Approximation
Register (SAR) analog-to-digital converter (ADC)
includes the following features:
• 12-bit resolution
• Seven ADC modules with dedicated Sample and
Hold (S&H) circuits
• Two dedicated ADC modules can be combined in
Turbo mode to provide double conversion rate
• Up to 45 analog input sources, in addition to the
internal CTMU, VBAT, internal voltage reference
and internal temperature sensor
• Single-ended and/or differential inputs
• Supports touch sense applications
• Four digital comparators
• Four digital filters supporting two modes:
- Oversampling mode
- Averaging mode
• Early interrupt generation resulting in faster
processing of converted data
• Designed for power conversion and general
purpose applications
• Operation during Sleep and Idle modes
A simplified block diagram of the ADC module is
illustrated in Figure 25-1.
The 12-bit HS SAR ADC has up to six dedicated
ADC modules (ADC0-ADC5) and one shared ADC
module (ADC7). The dedicated ADC modules use a
single input (or its alternate) and are intended for
high-speed and precise sampling of time-sensitive or
transient inputs. The shared ADC module
incorporates a multiplexer on the input to facilitate a
larger group of inputs, with slower sampling, and
provides flexible automated scanning option through
the input scan logic.
2016-2019 Microchip Technology Inc.
For each ADC module, the analog inputs are
connected to the S&H capacitor. The clock, sampling
time, and output data resolution for each ADC
module can be set independently. The ADC module
performs the conversion of the input analog signal
based on the configurations set in the registers.
When conversion is complete, the final result is
stored in the result buffer for the specific analog
input and is passed to the digital filter and digital
comparator if configured to use data from this
particular sample. Input to ADCx mapping is
illustrated in Figure 25-2.
25.1
Activation Sequence
The following ADCx activation sequence is to be
followed at all times:
Step 1: Initialize the ADC calibration values by
copying them from the factory programmed
DEVADCx Flash locations starting at 0xBFC45000
into the ADCxCFG registers starting at 0xBF887D00,
respectively.
Then, configure the AICPMPEN bit (ADCCON1
and the IOANCPEN bit (CFGCON) = 1 if and
only if VDD is less than 2.5V. The default is ‘0’, which
assumes VDD is greater than or equal to 2.5V.
Step 2: The user writes all the essential ADC
configuration SFRs including the ADC control clock
and all ADC core clocks setup:
• ADCCON1, keeping the ON bit = 0
• ADCCON2, especially paying attention to
ADCDIV and SAMC
• ADCANCON, keeping all analog enables ANENx
bit = 0
• ADCCON3, keeping all DIGEN5x = 0, especially
paying attention to ADCSEL, CONCLKDIV
, and VREFSEL
• ADCxTIME, especially paying attention to
ADCDIVx and SAMCx
• ADCTRGMODE, ADCIMCONx, ADCTRGSNS,
ADCCSSx, ADCGIRQENx, ADCTRGx, ADCBASE
• Comparators, Filters, etc.
Step 3: The user sets the ON bit to ‘1’, which enables
the ADC control clock.
Step 4: The user waits for the interrupt/polls the
status bit BGVRRDY = 1, which signals that the
device analog environment (band gap and VREF) is
ready.
Step 5: The user sets the ANENx bit to ‘1’ for the
ADC SAR Cores needed (which internally in the
ADC module enables the control clock to generate
by division the core clocks for the desired ADC SAR
Cores, which in turn enables the bias circuitry for
these ADC SAR Cores).
DS60001402G-page 371
PIC32MK GP/MC Family
Step 6: The user waits for the interrupt/polls the
warm-up ready bits WKRDYx = 1, which signals that
the respective ADC SAR Cores are ready to operate.
Step 7: The user sets the DIGENx bit to ‘1’, which
enables the digital circuitry to immediately begin
processing incoming triggers to perform data
conversions.
Note:
For the best optimized CPU and ISR performance, refer to TABLE 8-1: “ISR
Latency Information”. To complete the
optimization, the user application should
define ISRs that use the ‘at vector’ attribute (see Table 8-1). The CPU interrupt
latency is ~43 SYSCLK cycles if no other
interrupts are pending. If not using ADC
DMA, and the ADC combined sum
throughput rate of all the ADC modules in
use is greater than (SYSCLK/ 43) = 2.8
Msps, it is recommended to use the ADC
CPU early interrupt generation, defined in
the ADCxTIME and ADCEIENx registers
(see Register 25-33, Register 25-34, and
Register 25-35). This will reduce the probability of the ADC results being overwritten by the next conversion before the CPU
can read the previous ADC results.
Do not use the early interrupts if using the
ADC in the DMA module.

Note 1:
Interleaved ADCs in this context means
connecting the same analog source signal
to multiple dedicated Class_1 ADCs (that
is, ADC0-ADC5), and using independent
staggered trigger sources accordingly for
each interleaved ADC.
Do not activate ADC triggers sources until after ADC
has been completely initialized, enabled, and warm up
time complete.
NOTE: If using ADC DMA, ADC source clock must
be SYSCLK only.
Dedicated Class 1 ADCx Throughput rate =
1/((Sample time + Conversion time)(TAD))
= 1 / ((SAMC+# bit resolution+1)(TAD))
Example:
SAMC = 3 TAD, 12-bit mode, TAD = 16.667 ns = 60
MHz:
Throughput rate = 1 / ((3+12+1)(16.667 ns))
= 1/(16 * 16.667 ns)
= 3.75 Msps

PIC32MK GP/MC devices include several features
intended to maximize application flexibility and reliability and minimize cost through elimination of external
components. These are:
•
•
•
•
The following run-time programmable Configuration
registers provide additional configuration control:
• CFGCON: Configuration Control Register
• CFGPG: Permission Group Configuration
Register
• CFGCON2: EE Data and Op amp Configuration
Register
In addition, the DEVID register (Register 33-10)
provides device and revision information, the
DEVADC1 through DEVADC5 registers (Register 3311) provide ADC module calibration data, and the
DEVSN0 and DEVSN3 registers contain a unique
serial number of the device (Register 33-12).
Note:
Do not use Word program operation
(NVMOP = 0001) when programming the device Words that are described
in this section.

Configuration Bits
PIC32MK GP/MC devices contain two Boot Flash
memories (Boot Flash 1 and Boot Flash 2), each with
an associated configuration space. These configuration spaces can be programmed to contain various
device configurations. Configuration space that is
aliased by the Lower Boot Alias memory region is used
to provide values for Configuration registers listed
below. See 4.1.1 “Boot Flash Sequence and Configuration Spaces” for more information.

Note:
Note 1:
On Reset, this Configuration bit is copied into JTAGEN (CFGCON). If JTAGEN
(DEVCFG0) = 0, the JTAGEN bit cannot be set to ‘1’ by the user application at
run-time, as JTAG is always disabled. However, if JTAGEN (DEVCFG0) = 1, the
user application may enable/disable JTAG at run-time as by simply writing JTAGEN
(CFGCON as required.
When the FJTAGEN or JTAGEN bits are equal to ‘0’, this prevents 4-wire JTAG debugging, but
not PGECx/PGEDx debugging.
This bit sets the value of the JTAGEN bit in the CFGCON register.

Data in the “Typical” column is at 3.3V, +25°C unless otherwise stated. Parameters are for design guidance
only and are not tested.
The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified
levels represent normal operating conditions. Higher leakage current may be measured at different input
voltages.
Negative current is defined as current sourced by the pin.
This parameter is characterized, but not tested in manufacturing.
See the pin name tables (Table 3 and Table 5) for the 5V-tolerant pins.
The VIH specifications are only in relation to externally applied inputs, and not with respect to the userselectable internal pull-ups. External open drain input signals utilizing the internal pull-ups of the PIC32
device are guaranteed to be recognized only as a logic “high” internally to the PIC32 device, provided that
the external load does not exceed the minimum value of ICNPU. For External “input” logic inputs that require
a pull-up source, to guarantee the minimum VIH of those components, it is recommended to use an
external pull-up resistor rather than the internal pull-ups of the PIC32 device.

VIL source < (VSS - 0.3). Characterized but not tested.
VIH source > (VDD + 0.3) for non-5V tolerant pins only.
Digital 5V tolerant pins do not have an internal high side diode to VDD, and therefore, cannot tolerate any
“positive” input injection current.
Injection currents > | 0 | can affect the ADC results by approximately 4 to 6 counts (i.e., VIH Source > (VDD

Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted
provided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the
specified limit. If Note 2, IICL = (((Vss - 0.3) - VIL source) / Rs). If Note 3, IICH = ((IICH source - (VDD + 0.3))
/ RS). RS = Resistance between input source voltage and device pin. If (VSS - 0.3) VSOURCE (VDD +

These parameters are characterized, but not tested in manufacturing.
This jitter specification is based on clock-cycle by clock-cycle measurements. To get the effective jitter for
individual time-bases on communication clocks, use the following formula:
D CLK
EffectiveJitter = -------------------------------------------------------------PBCLKx
---------------------------------------------------------CommunicationClock
For example, if PBCLKx = 100 MHz and SPI bit rate = 50 MHz, the effective jitter is as follows:
