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/O mode can be selected by setting the
serial I/O mode selection bit of the serial I/O1 control register (bit
6 of address 001A
16
) 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” .
