UART Baud Rate Error (%)
The baud rate error relative to the appropriate baud rate is calculated using the following
equation:
For reliable communication, the LIN-UART baud rate error must never exceed 5 percent.
Table 92
commonly used crystal oscillator frequencies for normal UART mode of operation.
When the LIN-UART is disabled, the baud rate generator functions 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 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:
UART BRG Interrupt Interval (s)
register to 0 (
byte registers.
BRGCTL bit in the LIN-UART control 1 register to 1. Enable the UART receive
interrupt in the interrupt controller.
