The signal from the external 24-MHz crystal is the source of the
CLK24M signal fed into USB PHY as the reference clock and to the
real time clock (RTC).
DPLLs are used to generate the clocks:
MCU PLL (MPLL)—programmable
Peripheral PLL (PPLL)—programmable
The pulse-width modulator (PWM) is optimized to generate sound
from stored sample audio images; it can also generate tones.
Provides the ARM1136 platform with a clock function (days, hours,
minutes, seconds) and includes alarm, sampling timer, and minute
stopwatch capabilities.
The SDMA provides DMA capabilities inside the processor. It is a
shared module that implements 32 DMA channels and has an
interface to connect to the ARM1136 platform subsystem, EMI
interface, and the peripherals.
The secure JTAG controller (SJC) provides debug and test control
with maximum security.
The SPBA controls access to the SDMA peripherals. It supports
shared peripheral ownership and access rights to an owned
peripheral.
Sony/Philips digital transceiver interface
The SSI is a full-duplex serial port that allows the processor
connected to it to communicate with a variety of serial protocols,
including the Freescale Semiconductor SPI standard and the I2C
sound (I2S) bus standard. The SSIs interface to the AUDMUX for
flexible audio routing.
Each UART provides serial communication capability with external
devices through an RS-232 cable using the standard RS-232
non-return-to-zero (NRZ) encoding format. Each module transmits
and receives characters containing either 7 or 8 bits
(program-selectable). Each UART can also provide low-speed IrDA
compatibility through the use of external circuitry that converts
infrared signals to electrical signals (for reception) or transforms
electrical signals to signals that drive an infrared LED (for
transmission).
