SERIAL I/O
Serial I/O can be used as either clock synchronous or asynchro-
nous (UART) serial I/O. A dedicated timer (baud rate generator) 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
mode selection bit of the serial I/O control register 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 (address 0018
16
).

Notes 1 :
The transmit interrupt (TI) can be generated either when the transmit buffer register 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/O 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 T
X
D pin.
3 :
The receive interrupt (RI) is set when the receive buffer full flag (RBF) becomes “1” .
