CHAPTER 20 SERIAL INTERFACE CHANNEL 2
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 SCK : 5-bit counter source clock
