Other than above Setting prohibited
Caution When a data is written to BRGC during a communication operation, baud rate generator
output is disrupted and communication cannot be performed normally. Therefore, data
must not be written to BRGC during a communication operation.
Remarks 1. fX: Main system clock oscillation frequency
2. fXX : Main system clock frequency (fX or fX/2)
3. MCS : Oscillation mode selection register (OSMS) bit 0
4. n : Value set in TPS0 to TPS3 (1 ≤ n ≤ 11)
5. Figures in parentheses apply to operation with fX = 5.0 MHz.
