Serial communication interface 3 (SCI3) has both synchronous and asynchronous serial data
communication capabilities. It also has a multiprocessor communication function for serial data
communication among two or more processors.
Features
SCI3 features are listed below.
248
Selection of asynchronous or synchronous mode
Full duplex communication
The transmitting and receiving sections are independent, so SCI3 can transmit and receive
simultaneously. Both sections use double buffering, so continuous data transfer is possible in
both the transmit and receive directions.
Built-in baud rate generator with selectable bit rates.
Internal or external clock may be selected as the transfer clock source.
There are six interrupt sources: transmit end, transmit data empty, receive data full, overrun
error, framing error, and parity error.
Asynchronous mode
Synchronous mode
Serial data communication is performed using an asynchronous method in which
synchronization is established character by character.
SCI3 can communicate with a UART (universal asynchronous receiver/transmitter), ACIA
(asynchronous communication interface adapter), 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.
Serial data communication is synchronized with a clock signal. SCI3 can communicate
with other chips having a clocked synchronous communication function.
SCI3
Overview
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
Data length: eight bits
Receive error detection: overrun errors
