Fig. 61 Operation of clock synchronous serial I/O2 function
●Serial I/O2
Serial I/O2 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/O2 Mode
Clock synchronous serial I/O2 mode can be selected by setting
the serial I/O2 mode selection bit of the serial I/O2 control register
(bit 6) to “1”.
For clock synchronous serial I/O2, 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), 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/O2 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 TxD2 pin.
3: The receive interrupt (RI) is set when the receive buffer full flag (RBF) becomes “1” .
