Subsystem
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 I
sound (I
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).
The USB module provides high performance USB on-the-go (OTG)
functionality (up to 480 Mbps), compliant with the USB 2.0
specification, the OTG supplement, and the ULPI 1.0 low pin count
specification. The module has DMA capabilities handling data
transfer between internal buffers and system memory.
Each module protects against system failures by providing a method
of escaping from unexpected events or programming errors. Once
activated, the timer must be serviced by software on a periodic basis.
If servicing does not take place, the watchdog times out and then
either asserts a system reset signal or an interrupt request signal,
depending on the software configuration.
