13.1
The SuperH microcomputer has a serial communication interface (SCI) with two independent
channels. Both channels are functionally identical. The SCI supports both asynchronous and
synchronous serial communication. It also has a multiprocessor communication function for serial
communication between two or more processors.
13.1.1
SCI features are listed below:
Asynchronous mode
Synchronous mode
Full duplex communication: The transmitting and receiving sections are independent, so the
SCI can transmit and receive simultaneously. Both sections use double buffering, so
continuous data transfer is possible in both the transmit and receive directions.
On-chip baud rate generator with selectable bit rates
Serial data communication is synchronized using a start-stop method in character units.
The SCI can communicate with a universal asynchronous receiver/transmitter (UART), an
asynchronous communication interface adapter (ACIA), or any 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: seven or eight bits
Stop bit length: one or two bits
Parity: even, odd, or none
Multiprocessor bit: one or none
Receive error detection: parity, overrun, and framing errors
Break detection: by reading the RxD level directly when a framing error occurs
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: eight bits
Receive error detection: overrun errors
