12.1
The H8/3437 Series includes two serial communication interface channels (SCI0 and SCI1) for
transferring serial data to and from other chips. Either synchronous or asynchronous
communication can be selected.
12.1.1
The features of the on-chip serial communication interface are:
Asynchronous mode
The H8/3437 Series can communicate with a UART (Universal Asynchronous
Receiver/Transmitter), ACIA (Asynchronous Communication Interface Adapter), or other chip
that employs standard asynchronous serial communication. It also has a multiprocessor
communication function for communication with other processors. Twelve data formats are
available.
Synchronous mode
The SCI can communicate with chips able to perform clocked synchronous data transfer.
Full duplex communication
The transmitting and receiving sections are independent, so each channel can transmit and
receive simultaneously. Both the transmit and receive sections use double buffering, so
continuous data transfer is possible in either direction.
Built-in baud rate generator
Any specified bit rate can be generated.
Internal or external clock source
The SCI can operate on an internal clock signal from the baud rate generator, or an external
clock signal input at the SCK0 or SCK1 pin.
Data length: 7 or 8 bits
Stop bit length: 1 or 2 bits
Parity: Even, odd, or none
Multiprocessor bit: 1 or 0
Error detection: Parity, overrun, and framing errors
Break detection: When a framing error occurs, the break condition can be detected by
Data length: 8 bits
Error detection: Overrun errors
reading the level of the RxD line directly.
