communication among 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. The baud rate clock source for the SCI is the bus clock.
9.4.1 Data Format
The SCI uses the standard non-return-to-zero mark/space data format illustrated in
