Data Sheet

NOTE:
NOTE:
The SCI allows full-duplex, asynchronous, NRZ serial communication
between the MCU and remote devices, including other MCUs. The
transmitter and receiver of the SCI operate independently, although they
use the same baud rate generator. During normal operation, the CPU
monitors the status of the SCI, writes the data to be transmitted, and
processes received data.
For SCI operations, the IR sub-module is transparent to the SCI module.
Data at going out of the SCI transmitter and data going into the SCI
receiver is always in SCI format. It makes no difference to the SCI
module whether the IR sub-module is enabled or disabled.
This SCI module is a standard HC08 SCI module with the following
modifications:
The SCI uses the standard non-return-to-zero mark/space data format
