Chapter 8 Serial Communication Interface (SCIV4)
8.4
This subsection provides a complete functional description of the SCI block, detailing the operation of the
design from the end user’s perspective in a number of descriptions.

communication between the CPU and remote devices, including other CPUs. The SCI transmitter and
receiver operate independently, although they use the same baud rate generator. The CPU monitors the
status of the SCI, writes the data to be transmitted, and processes received data.
