13.1
The H8/3048 Group has a serial communication interface (SCI) with two independent channels.
The two channels are functionally identical. The SCI can communicate in asynchronous or
synchronous mode. It also has a multiprocessor communication function for serial communication
among two or more processors.
When the SCI is not used, it can be halted to conserve power. Each SCI channel can be halted
independently. For details see section 21.6, Module Standby Function.
Channel 0 (SCI0) also has a smart card interface function conforming to the ISO/IEC7816-3
(Identification Card) standard. This function supports serial communication with a smart card. For
details, see section 14, Smart Card Interface.
13.1.1
SCI features are listed below.
Selection of asynchronous or synchronous mode for serial communication
Data length: 7 or 8 bits
Stop bit length: 1 or 2 bits
Parity bit: even, odd, or none
Multiprocessor bit: 1 or 0
Receive error detection: parity, overrun, and framing errors
Break detection: by reading the RxD level directly when a framing error occurs
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.
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.
