SERIAL INTERFACE
The
μ
PD78362A is provided with the following two independent serial interfaces:
Asynchronous serial interface (UART)
Clocked serial interface
3-line serial I/O mode
Serial bus interface mode (SBI mode)
Since the
μ
PD78362A contains a baud rate generator (BRG), any serial transfer rate can be set regardless
of the operating clock frequency. The baud rate generator is a block to generate the shift clock for the transmit/
receive serial interface, and is used commonly with the two channels of the serial interfaces.
The serial transfer rate can be selected in a range of 110 bps to 38.4 Kbps by the mode register.
