9.1 Overview
The H8/325 series chips include a serial communication interface module (SCI) with two channels
for transferring serial data to and from other chips. Either synchronous or asynchronous
communication can be selected. Communication control functions are provided by internal
registers.
9.1.1 Features
The features of the on-chip serial communication interface are:
• Asynchronous and synchronous modes
• Full duplex communication
• Built-in baud rate generator
• Internal or external clock source
• Three interrupts
– Asynchronous mode
– Synchronous mode
The transmitting and receiving sections are independent, so the SCI can transmit and receive
simultaneously. Both the transmit and receive sections use double buffering, so continuous data
transfer is possible in either direction.
Any specified baud rate can be generated.
The baud rate generator can operate on an internal clock source, or an external clock signal can
be input at the SCK pin.
Transmit-end, receive-end, and receive-error interrupts are requested independently.
The SCI can communicate with a UART (Universal Asynchronous Receiver/Transmitter),
ACIA (Asynchronous Communication Interface Adapter), or other chip that employs standard
asynchronous serial communication. Eight data formats are available.
– Data length: 7 or 8 bits
– Stop bit length: 1 or 2 bits
– Parity: Even, odd, or none
– Error detection: Parity, overrun, and framing errors
The SCI can communicate with chips able to perform clocked serial data transfer.
– Data length: 8 bits
– Error detection: Overrun errors
