12.1
The H8/3008 has a serial communication interface (SCI) with two independent channels. The two
channels have identical functions. The SCI can communicate in both asynchronous and
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 18.6, Module Standby Function.
The SCI also has a smart card interface function conforming to the ISO/IEC 7816-3 (Identification
Card) standard. This function supports serial communication with a smart card. Switching
between the normal serial communication interface and the smart card interface is carried out by
means of a register setting.
12.1.1
SCI features are listed below.
• Selection of synchronous or asynchronous 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 communication. It
can also communicate with two or more other processors using the multiprocessor
communication function. There are twelve selectable serial data transfer formats.
⎯ Data length:
⎯ Stop bit length:
⎯ Parity:
⎯ Multiprocessor bit:
⎯ Receive error detection:
⎯ 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 a single serial data communication format.
