TMPR3922AU
5.3.6 CONCENTRATION HIGHWAY INTERFACE (CHI) MODULE
The TMPR3922AU has a CHI module with the following features.
high-speed serial Concentration Highway Interface (CHI) contains logic for interfacing to
external full-duplex serial time-division-multiplexed (TDM) communication peripherals
supports ISDN line interface chips and other PCM/TDM serial devices
CHI interface is programmable (number of channels, frame rate, bit rate, etc.) to provide
support for a variety of formats
supports data rates up to 4.096 Mbps
independent DMA support for CHI receive and transmit
5.3.7 INTERRUPT MODULE
The TMPR3922AU has an Interrupt module with the following features.
contains logic for individually enabling, reading, and clearing all TMPR3922AU interrupt
sources
interrupts generated from internal TMPR3922AU modules or from edge transitions on external
signal pins
5.3.8 IO MODULE
The TMPR3922AU has an IO module with the following features.
contains support for reading and writing the 16 bi-directional general purpose IO pins and
the 32 bi-directional multi-function IO pins
each IO port can generate a separate positive and negative edge interrupt
independently configurable IO ports allow the TMPR3922AU to support a flexible and wide
range of system applications and configurations
