LIN-UART Baud Rate Generator
Baud Rate Generator Interrupts
If the
with MSEL =
LIN-UART Receiver interrupt asserts when the LIN-UART Baud Rate Generator reloads.
This action allows the Baud Rate Generator to function as an additional counter, if the
LIN-UART receiver functionality is not employed. The transmitter can be enabled in this
mode.
The LIN-UART Baud Rate Generator creates a lower frequency baud rate clock for data
transmission. The input to the Baud Rate Generator is the system clock. The LIN-UART
Baud Rate High and Low Byte registers combine to create a 16-bit baud rate divisor value
(
LIN-UART data rate for normal UART operation is calculated using the following
equation:
The LIN-UART data rate for LIN mode UART operation is calculated using the following
equation:
When the LIN-UART is disabled, the BRG functions as a basic 16-bit timer with 
interrupt on timeout. To configure the BRG as a timer with interrupt on timeout, follow the
procedure below:
1. Disable the LIN-UART receiver by clearing the
2. Load the appropriate 16-bit count value into the LIN-UART Baud Rate High and Low
3. Enable the BRG timer function and the associated interrupt by setting the BRGCTL bit
