13.1
The chip is equipped with 3 independent serial communication interface (SCI) channels. The SCI
can handle both asynchronous and clocked synchronous serial communication. A function is also
provided for serial communication between processors (multiprocessor communication function).
13.1.1
SCI features are listed below.
• Choice of asynchronous or clocked synchronous serial communication mode

Asynchronous mode
⎯ Serial data communication executed using asynchronous system in which synchronization
⎯ A multiprocessor communication function is provided that enables serial data
⎯ Choice of 12 serial data transfer formats
⎯ Receive error detection : Parity, overrun, and framing errors
⎯ Break detection
Clocked Synchronous mode
⎯ Serial data communication synchronized with a clock
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)
communication with a number of processors
Data length
Stop bit length
Parity
Multiprocessor bit
Serial data communication can be carried out with other chips that have a synchronous
communication function

: 7 or 8 bits
: 1 or 2 bits
: Even, odd, or none
: 1 or 0
: Break can be detected by reading the RxD pin level directly in
case of a framing error
