The BRR setting is calculated as follows:
The bit rate error in asynchronous mode is calculated as follows:
Asynchronous mode:
N =
Synchronous mode:
N =
B: Bit rate (bit/s)
N: Baud rate generator BRR setting (0
n: Baud rate generator input clock (n = 0 to 3)
(See the following table for the clock sources and value of n.)
