(2) Asynchronous serial I/O (UART) mode
The asynchronous serial I/O (UART) mode can be selected by
clearing the serial I/O2 mode selection bit (b6) of the serial I/O2
control register (address 001D16) to “0”. Eight serial data transfer
formats can be selected and the transfer formats used by the
transmitter and receiver must be identical.
The transmit and receive shift registers each have a buffer (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 re-
ceive buffer. The transmit buffer can also hold the next data to be
transmitted, and the receive buffer can receive 2-byte data con-
tinuously.
