3.13
The XC886/888 provides two Universal Asynchronous Receiver/Transmitter (UART and
UART1) modules for full-duplex asynchronous reception/transmission. Both are also
receive-buffered, i.e., they can commence reception of a second byte before a
previously received byte has been read from the receive register. However, if the first
byte still has not been read by the time reception of the second byte is complete, one of
the bytes will be lost.

The UART modules can operate in the four modes shown in
Table 29
Operating Mode
Mode 0: 8-bit shift register
Mode 1: 8-bit shift UART
Mode 2: 9-bit shift UART
Mode 3: 9-bit shift UART
1) For UART1 module, the baud rate is fixed at f
There are several ways to generate the baud rate clock for the serial port, depending on
the mode in which it is operating. In mode 0, the baud rate for the transfer is fixed at
f
and can be configured to either
available. The variable baud rate is set by the underflow rate on the dedicated baud-rate
generator. For UART module, the variable baud rate alternatively can be set by the
overflow rate on Timer 1.
3.13.1
Both UART modules have their own dedicated baud-rate generator, which is based on
a programmable 8-bit reload value, and includes divider stages (i.e., prescaler and
