Baud rate generator control register (BRGCR)
This register sets the serial clock for serial interface. BRGCR is
set by an 8 bit memory manipulation instruction. The RESET in-
put sets BRGCR to -001_0000B.
Figure 17-6 shows the format of BRGCR.

Remarks
Writing to BRGCR0 during a communication operation may cause abnormal output from the baud rate generator and
disable further communication operations. Therefore, do not write to BRGCR0 during a communication operation.
