Section 12 Serial Communication Interface (SCI)
12.1
Overview
The chip is equipped with a serial communication interface (SCI) that can handle both
asynchronous and synchronous serial communication. A function is also provided for serial
communication between processors (multiprocessor communication function).
12.1.1
Features
SCI features are listed below.
•
Choice of asynchronous or synchronous serial communication mode
Asynchronous mode
Serial data communication executed using an asynchronous system in which
synchronization is achieved character by character
Serial data communication can be carried out with standard asynchronous communication
chips such as a Universal Asynchronous Receiver/Transmitter (UART) or Asynchronous
Communication Interface Adapter (ACIA)
A multiprocessor communication function is provided that enables serial data
communication with a number of processors
Choice of 12 serial data transfer formats
Data length
: 7 or 8 bits
Stop bit length
: 1 or 2 bits
Parity
: Even, odd, or none
Multiprocessor bit
: 1 or 0
Receive error detection : Parity, overrun, and framing errors
Break detection
: Break can be detected by reading the RxD pin level
directly in case of a framing error
Synchronous mode
Serial data communication synchronized with a clock
Serial data communication can be carried out with other chips that have a synchronous
communication function
One serial data transfer format
Data length
: 8 bits
Receive error detection : Overrun errors detected
