Write to this register w hile the serial I/O is neither transmitting nor receiving.
Use the MOV instruction to w rite to this register.
After setting the CLK0 to CLK1 bits of the UiC0 register, w rite to the UiBRG register.
When the CLK0 pin is used, set the PD1_6 bit in the PD1 register to 0 (input). When the CLK1 pin is used, set the
PD0_5 bit in the PD0 register to 0 (input).
