NOTE:
NOTE:
Section 14. Infrared Serial Communications
The MC68HC908AP64 has two SCI modules:
This section describes SCI2, 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.
When the IRSCI is enabled, the SCTxD pin is an open-drain output and
requires a pullup resistor to be connected for proper SCI operation.
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.
