(2) Asynchronous Serial I/O (UART) Mode
Clock asynchronous serial I/O mode (UART) can be selected by
clearing the serial I/O3 mode selection bit (b6) of the serial I/O3
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 the buffer
register 3, but the two buffers have the same address in a
memory. Since the shift register cannot be written to or read from
directly, transmit data is written to the transmit buffer register 3,
and receive data is read from the receive buffer register 3.
The transmit buffer register can also hold the next data to be
transmitted, and the receive buffer register 3 can hold a character
while the next character is being received.

Notes 1: Error flag detection occurs at the same time that the RBF flag becomes “1” (at 1st stop bit, during reception).
2: As the transmit interrupt (TI), when either the TBE or TSC flag becomes “1”, can be selected to occur depending on the setting of the transmit interrupt source
selection bit (TIC) of the serial I/O3 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 3 when TSC=1, 0.5 to 1.5 cycles of the data shift cycle are necessary until changing to TSC=0.
