(BRG[15:0]) that sets the data transmission rate (baud rate) of the UART. The UART data
rate is calculated using the following equation:
When the UART is disabled, the Baud Rate Generator can function as a basic 16-bit timer
with interrupt on time-out. To configure the Baud Rate Generator as a timer with interrupt
on time-out, complete the following procedure:
1. Disable the UART by clearing the REN and TEN bits in the UART Control 0 register
2. Load the desired 16-bit count value into the UART Baud Rate High and Low Byte
3. Enable the Baud Rate Generator timer function and associated interrupt by setting the
When configured as a general purpose timer, the interrupt interval is calculated using the
following equation:
The UART control registers support the UART and the associated Infrared Encoder/
Decoders. For more information on the infrared operation, see
on page 121.
