(2) Asynchronous Serial I/O (UART) Mode
Clock asynchronous serial I/O mode (UART) can be selected by
clearing the serial I/O mode selection bit of the serial I/O1 control
register to
“
0
”
.
Eight serial data transfer formats can be selected, and the transfer
formats used by a transmitter and receiver must be identical.
The transmit and receive shift registers each have a buffer regis-
ter, but the two buffers have the same address in memory. Since
the shift register cannot be written to or read from directly, transmit
data is written to the transmit buffer, and receive data is read from
the receive buffer.
The transmit buffer can also hold the next data to be transmitted,
and the receive buffer register can hold a character while the next
character is being received.

Transmit buffer write signal

1 or 2 stop bit (s)
1 :
Error flag detection occurs at the same time that the RBF flag becomes
“
1
”
(at 1st stop bit, during reception).
2 :
The transmit interrupt (TI) can be selected to occur when either the TBE or TSC flag becomes
“
1
”
by the setting of the transmit interrupt source
selection bit (TIC) of the serial I/O1 control register.
3 :
The receive interrupt (RI) is set when the RBF flag becomes
“
1
”
.
4 :
After data is written to the transmit buffer register when TSC=1, 0.5 to 1.5 cycles of the data shift cycle is necessary until changing to TSC=0.
