Subsystem
The SSI is a full-duplex synchronous interface used on the i.MX50 processor
to provide connectivity with off-chip audio peripherals. The SSI interfaces
connect internally to the AUDMUX for mapping to external ports. The SSI
supports a wide variety of protocols (SSI normal, SSI network, I2S, and
AC-97), bit depths (up to 24 bits per word), and clock/frame sync options.
Each SSI has two pairs of 8 x 24 FIFOs and hardware support for an external
DMA controller in order to minimize its impact on system performance. The
second pair of FIFOs provides hardware interleaving of a second audio
stream, which reduces CPU overhead in use cases where two time slots are
being used simultaneously.
The temperature sensor is an internal module to the i.MX50 that monitors the
die temperature.
Each of the UARTv2 modules supports the following serial data
transmit/receive protocols and configurations:
USB-OH-1 supports USB2.0 HS/FS/LS, and contains:
The Watchdog (WDOG) timer module protects against system failures by
providing a method of escaping from unexpected events or programming
errors. The WDOG Timer supports two comparison points during each
counting period. Each of the comparison points is configurable to invoke an
interrupt to the ARM core, and a second point invokes an external event on
the WDOG line.
The XTALOSC module combined with an external 24 MHz crystal with load
capacitors implements a crystal oscillator.
