Setting prohibited
Caution
When a write is performed to BRGC during a communication operation, baud rate
generator output is disrupted and communication cannot be performed normally.
Therefore, BRGC must not be written to during a communication operation.
Remarks 1. f
X
:
Main system clock oscillation frequency
2. f
XX
:
Main system clock frequency (f
X
or f

3. MCS :
Oscillation mode selection register (OSMS) bit 0
4. n
:
Value set in TPS0 to TPS3 (1
