When the LIN-UART is disabled, the baud rate generator functions as a basic 16-bit timer
with interrupt on timeout. To configure the baud rate generator as a timer with interrupt on
timeout, complete the following procedure:
1. Disable the LIN-UART receiver by clearing the REN bit in the LIN-UART Control 0
2. Load the appropriate 16-bit count value into the LIN-UART baud rate high and low
3. Enable the baud rate generator timer function and associated interrupt by setting the
When configured as a general purpose timer, the BRG interrupt interval is calculated using
the following equation:
