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

Notes 1:
As the transmit interrupt (TI), which can be selected, 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” .
