13.1 Overview
The H8/3003 has a serial communication interface (SCI) with two independent channels. Both
channels are functionally identical. The SCI can communicate in asynchronous mode or
synchronous mode, and has a multiprocessor communication function for serial communication
among two or more processors.
13.1.1 Features
SCI features are listed below.
•
a.
b.
Selection of asynchronous or synchronous mode for serial communication
Asynchronous mode
Serial data communication is synchronized one character at a time. The SCI can communicate
with a universal asynchronous receiver/transmitter (UART), asynchronous communication
interface adapter (ACIA), or other chip that employs standard asynchronous serial
communication. It can also communicate with two or more other processors using the
multiprocessor communication function. There are twelve selectable serial data
communication formats.
— Data length:
— Stop bit length:
— Parity bit:
— Multiprocessor bit:
— Receive error detection: parity, overrun, and framing errors
— Break detection:
Synchronous mode
Serial data communication is synchronized with a clock signal. The SCI can communicate
with other chips having a synchronous communication function. There is one serial data
communication format.
— Data length:
— Receive error detection: overrun errors
