(5) Baud rate generator mode control register 1 (BRGMC1)
Cautions 1. If write is performed to BRGMC1 during communication processing, the output of the baud
Remarks 1. Source clock of 8-bit counter: f
This register sets the UART1 source clock.
BRGMC1 is set by an 8-bit memory manipulation instruction.
RESET input sets this register to 00H.
After reset: 00H

2. Be sure to set bits 3 to 7 to 0.
2. When the selected clock is timer the output, it is not necessary to set the P26/TI2/TO2 pin to timer
