1. Write to this register while serial interface is neither transmitting nor receiving.
2. Use MOV instruction to write to this register.
3. After setting the CLK0 to CLK1 bits of the UiC0 register, write to the UiBRG register.

NOTES:
1. Read out the UiRB register in 16-bit unit.
2. All of the SUM, PER, FER and OER bits are set to “0” (no error) when the SMD2 to SMD0 bits in the UiMR register are set to “000
disabled) or the RE bit in the UiC1 register is set to “0” (reception disabled). The SUM bit is set to “0” (no error) when all of the PER, FER and OER
bits are set to “0” (no error).
The PER and FER bits are set to “0” even when the higher byte of the UiRB register is read.
