14.1
The H8S/2357 Group is equipped with a three-channel serial communication interface (SCI). All three channels have the
same functions. The SCI can handle both asynchronous and clocked synchronous serial communication. A function is also
provided for serial communication between processors (multiprocessor communication function).
14.1.1
SCI features are listed below.
Choice of asynchronous or clocked synchronous serial communication mode
Asynchronous mode
Clocked Synchronous mode
Full-duplex communication capability
Choice of LSB-first or MSB-first transfer
On-chip baud rate generator allows any bit rate to be selected
Choice of serial clock source
Serial data communication executed using asynchronous system in which synchronization is achieved character by
Serial data communication can be carried out with standard asynchronous communication chips such as a Universal
A multiprocessor communication function is provided that enables serial data communication with a number of
Choice of 12 serial data transfer formats
Receive error detection : Parity, overrun, and framing errors
Break detection
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
Receive error detection : Overrun errors detected
The transmitter and receiver are mutually independent, enabling transmission and reception to be executed
Double-buffering is used in both the transmitter and the receiver, enabling continuous transmission and continuous
Can be selected regardless of the communication mode* (except in the case of 7-bit data asynchronous mode)
