OVERBAR is used to indicate a signal that is active when pulled low: for example, RESET.
Logic level one is a voltage that corresponds to Boolean true (1) state.
Logic level zero is a voltage that corresponds to Boolean false (0) state.
To set a bit or bits means to establish logic level one.
To clear a bit or bits means to establish logic level zero.
A signal is an electronic construct whose state conveys or changes in state convey information.
A pin is an external physical connection. The same pin can be used to connect a number of signals.
Asserted means that a discrete signal is in active logic state.
— Active low signals change from logic level one to logic level zero.
— Active high signals change from logic level zero to logic level one.
Negated means that an asserted discrete signal changes logic state.
— Active low signals change from logic level zero to logic level one.
— Active high signals change from logic level one to logic level zero.
LSB means least significant bit or bits, and MSB means most significant bit or bits. References to
low and high bytes or words are spelled out.
Numbers preceded by a percent sign (%) are binary. Numbers preceded by a dollar sign ($) or 0x
are hexadecimal.

I/O Pads Power Supply and Signal Multiplexing Scheme
This section describes detailed information about both the power supply for each I/O pin and its function
multiplexing scheme. The user can reference information provided in Table 6 on page 17 to configure the
power supply scheme for each device in the system (memory and external peripherals). The function
multiplexing information also shown in Table 6 allows the user to select the function of each pin by
configuring the appropriate GPIO registers when those pins are multiplexed to provide different functions.

A typical application with 30 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the ARM®
core-that is, 7x GPIO, 15x Data bus, and 8x Address bus.
2 A worst-case application with 70 pads simultaneously switching assumes the GPIO toggling and instruction fetches from the
ARM core-that is, 32x GPIO, 30x Data bus, 8x Address bus. These calculations are based on the core running its heaviest OS
application at 100MHz, and where the whole image is running out of SDRAM. QVDD at 1.9V, NVDD and AVDD at 3.3V,
therefore, 180mA is the worst measurement recorded in the factory environment, max 5mA is consumed for OSC pads, with
each toggle GPIO consuming 4mA.
3.2
Recommended Operating Range
Table 5 provides the recommended operating ranges for the supply voltages and temperatures. The i.MXS
processor has multiple pairs of VDD and VSS power supply and return pins. QVDD and QVSS pins are
used for internal logic. All other VDD and VSS pins are for the I/O pads voltage supply, and each pair of
VDD and VSS provides power to the enclosed I/O pads. This design allows different peripheral supply
voltage levels in a system.
Because AVDD pins are supply voltages to the analog pads, it is recommended to isolate and noise-filter
the AVDD pins from other VDD pins.
For more information about I/O pads grouping per VDD, please refer to Table 2 on page 4.

Functional Description and Application Information
4.1
Embedded Trace Macrocell
All registers in the ETM9 are programmed through a JTAG interface. The interface is an extension of the
ARM920T processor’s TAP controller, and is assigned scan chain 6. The scan chain consists of a 40-bit
shift register comprised of the following:
• 32-bit data field
• 7-bit address field
• A read/write bit
The data to be written is scanned into the 32-bit data field, the address of the register into the 7-bit address
field, and a 1 into the read/write bit.
A register is read by scanning its address into the address field and a 0 into the read/write bit. The 32-bit
data field is ignored. A read or a write takes place when the TAP controller enters the UPDATE-DR state.
The timing diagram for the ETM9 is shown in Figure 2. See Table 9 for the ETM9 timing parameters used
in Figure 2.

POR width is dependent on the 32 or 32.768 kHz crystal oscillator start-up time. Design margin should allow for crystal
tolerance, i.MX chip variations, temperature impact, and supply voltage influence. Through the process of supplying crystals
for use with CMOS oscillators, crystal manufacturers have developed a working knowledge of start-up time of their crystals.
Typically, start-up times range from 400 ms to 1.2 seconds for this type of crystal.
If an external stable clock source (already running) is used instead of a crystal, the width of POR should be ignored in
calculating timing for the start-up process.
4.4
External Interface Module
The External Interface Module (EIM) handles the interface to devices external to the i.MXS processor,
including the generation of chip-selects for external peripherals and memory. The timing diagram for the
EIM is shown in Figure 5, and Table 12 defines the parameters of signals.

DTACK setup time
Clock refers to the system clock signal, HCLK, generated from the System DPLL
4.4.1
DTACK Signal Description
The DTACK signal is the external input data acknowledge signal. When using the external DTACK signal
as a data acknowledge signal, the bus time-out monitor generates a bus error when a bus cycle is not
terminated by the external DTACK signal after 1022 HCLK counts have elapsed. Only the CS5 group
supports DTACK signal function when the external DTACK signal is used for data acknowledgement.
4.4.2
DTACK Signal Timing
Figure 6 through Figure 9 show the access cycle timing used by chip-select 5. The signal values and units
of measure for this figure are found in the associated tables.

Maximum frequency of LCDC_CLK is 48 MHz, which is controlled by Peripheral Clock Divider Register.
Maximum frequency of SCLK is HCLK / 5, otherwise LD output will be wrong.
3 VSYN, HSYN and SCLK can be programmed as active high or active low. In the above timing diagram, all
these 3 signals are active high.
4 Tpix is the pixel clock period which equals LCDC_CLK period * (PCD + 1).
5 Ts is the shift clock period. Ts = Tpix * (panel data bus width).

SPI Timing Diagrams
To use the internal transmit (TX) and receive (RX) data FIFOs when the SPI module is configured as a
master, two control signals are used for data transfer rate control: the SS signal (output) and the SPI_RDY
signal (input). The SPI1 Sample Period Control Register (PERIODREG1) can also be programmed to a
fixed data transfer rate. When the SPI module is configured as a slave, the user can configure the SPI1
Control Register (CONTROLREG1) to match the external SPI master’s timing. In this configuration, SS
becomes an input signal, and is used to latch data into or load data out to the internal data shift registers,
as well as to increment the data FIFO. Figure 34 through Figure 38 show the timing relationship of the
master SPI using different triggering mechanisms.

Ts is the SCLK period which equals LCDC_CLK / (PCD + 1). Normally LCDC_CLK = 15ns.
VSYN, HSYN and OE can be programmed as active high or active low. In Figure 41, all 3 signals
are active low.
The polarity of SCLK and LD[15:0] can also be programmed.
SCLK can be programmed to be deactivated during the VSYN pulse or the OE deasserted period.
In Figure 41, SCLK is always active.
For T9 non-display region, VSYN is non-active. It is used as an reference.
XMAX is defined in pixels.
Pulse-Width Modulator
The PWM can be programmed to select one of two clock signals as its source frequency. The selected
clock signal is passed through a divider and a prescaler before being input to the counter. The output is
available at the pulse-width modulator output (PWMO) external pin. Its timing diagram is shown in
Figure 42 and the parameters are listed in Table 22.

USB Device Port
Four types of data transfer modes exist for the USB module: control transfers, bulk transfers, isochronous
transfers, and interrupt transfers. From the perspective of the USB module, the interrupt transfer type is
identical to the bulk data transfer mode, and no additional hardware is supplied to support it. This section
covers the transfer modes and how they work from the ground up.
Data moves across the USB in packets. Groups of packets are combined to form data transfers. The same
packet transfer mechanism applies to bulk, interrupt, and control transfers. Isochronous data is also moved
in the form of packets, however, because isochronous pipes are given a fixed portion of the USB
bandwidth at all times, there is no end-of-transfer.

Synchronous Serial Interface
The transmit and receive sections of the SSI can be synchronous or asynchronous. In synchronous mode,
the transmitter and the receiver use a common clock and frame synchronization signal. In asynchronous
mode, the transmitter and receiver each have their own clock and frame synchronization signals.
Continuous or gated clock mode can be selected. In continuous mode, the clock runs continuously. In gated
clock mode, the clock functions only during transmission. The internal and external clock timing diagrams
are shown in Figure 51 through Figure 53.
Normal or network mode can also be selected. In normal mode, the SSI functions with one data word of
I/O per frame. In network mode, a frame can contain between 2 and 32 data words. Network mode is
typically used in star or ring-time division multiplex networks with other processors or codecs, allowing
interface to time division multiplexed networks without additional logic. Use of the gated clock is not
allowed in network mode. These distinctions result in the basic operating modes that allow the SSI to
communicate with a wide variety of devices.

All the timings for the SSI are given for a non-inverted serial clock polarity (TSCKP/RSCKP = 0) and a non-inverted frame sync
(TFSI/RFSI = 0). If the polarity of the clock and/or the frame sync have been inverted, all the timing remains valid by inverting
the clock signal STCK/SRCK and/or the frame sync STFS/SRFS shown in the tables and in the figures.

There are 2 sets of I/O signals for the SSI module. They are from Port C primary function (pad 257 to pad 261) and Port B
alternate function (pad 283 to pad 288). When SSI signals are configured as outputs, they can be viewed both at Port C primary
function and Port B alternate function. When SSI signals are configured as input, the SSI module selects the input based on
status of the FMCR register bits in the Clock controller module (CRM). By default, the input are selected from Port C primary
function.
