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/O 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, but the
two buffers have the same address in memory. Since the shift reg-
ister cannot be written to or read from directly, transmit data is
written to the transmit buffer, and receive data is read from the re-
ceive buffer.
The transmit buffer can also hold the next data to be transmitted,
and the receive buffer can hold a character while the next charac-
ter is being received.
