Section 13 Serial Communication Interface
The BRR setting is calculated as follows:
Asynchronous mode:
Synchronous mode:
B: Bit rate (bits/s)
N: BRR setting for baud rate generator (0
n: Baud rate generator clock source (n = 0, 1, 2, 3)
The bit rate error in asynchronous mode is calculated as follows.
