This section describes the infrared serial communications interface
(IRSCI) module which allows high-speed asynchronous
communications with peripheral devices and other MCUs. This IRSCI
consists of an SCI module for conventional SCI functions and a software
programmable infrared encoder/decoder sub-module for
encoding/decoding the serial data for connection to infrared LEDs in
remote control applications.
References to DMA (direct-memory access) and associated functions
are only valid if the MCU has a DMA module. This MCU does not have
the DMA function. Any DMA-related register bits should be left in their
reset state for normal MCU operation.
