Section 14. Infrared Serial Communications

Interface Module (IRSCI)

14.1 Introduction

The MC68HC908AP64 has two SCI modules:

•

SCI1 is a standard SCI module, and

•

SCI2 is an infrared SCI module.

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.

NOTE:

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.

NOTE:

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.
