Cautions 1. If write is performed to BRGMC0, BRGMC01 during communication processing, the output
Remarks 1. Source clock of 8-bit counter: f
These registers set the UARTn source clock.
BRGMC0 and BRGMC01 are set by an 8-bit memory manipulation instruction.
RESET input sets these registers to 00H.

2. Be sure to set bits 3 to 7 of the BRGMC0 register to 0.
2. When the selected clock is the timer output, it is not necessary to set the P27/TI3/TO3 pin to timer

of the baud rate generator will be disturbed and communication will not be performed
normally. Therefore, do not write to BRGMC0, BRGMC01 during communication
processing.
