MOTOROLA

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.

NOTE:

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.

NOTE:

This SCI module is a standard HC08 SCI module with the following

modifications:

•

A control bit, CKS, is added to the SCI baud rate control register

to select between two input clocks for baud rate clock generation

•

The TXINV bit is removed from the SCI control register 1

14.6.1 Data Format

The SCI uses the standard non-return-to-zero mark/space data format

illustrated in Figure 14-6.
