SERIAL INTERFACE
Serial I/O1
Serial I/O1 can be used as either clock synchronous or
asynchronous (UART) serial I/O1. A dedicated timer is also
provided for baud rate generation.
(1) Clock Synchronous Serial I/O Mode
Clock synchronous serial I/O mode can be selected by setting the
serial I/O1 mode selection bit of the serial I/O1 control register
(bit 6 of address 001A16) to “1”.
For clock synchronous serial I/O, the transmitter and the receiver
must use the same clock. If an internal clock is used, transfer is
started by a write signal to the TB/RB.

Notes 1: As the transmit interrupt (TI), either when the transmit buffer has emptied (TBE=1) or after the transmit shift operation has ended
(TSC=1), by setting the transmit interrupt source selection bit (TIC) of the serial I/O1 control register.
2: If data is written to the transmit buffer register when TSC=0, the transmit clock is generated continuously and serial data is output
continuously from the TXD pin.
3: The receive interrupt (RI) is set when the receive buffer full flag (RBF) becomes “1”.
