Clock Asynchronous Serial I/O (UART)
The UART is a full duplex asynchronous transmit/receive unit. The
built-in clock divider and baud rate generator enable a broad range
of transmission speeds. Please refer to Block diagram of UART.
(1) Description
The transmit and receive shift registers have a buffer (consisting of
high and low order byte) each. Since the shift registers cannot be
written to or read from directly, transmit data is written to the trans-
mit buffer and receive data is read from the receive buffer. A trans-
mit or receive operation will be triggered by the transmit enable bit
and receive enable bit of the UART control register UCON (see
Structure of UART control register). The double function terminals
