1. Write to this register while serial I/O is neither transmitting nor receiving.
2. Use MOV instruction to write to this register.
3. Set the UiBRG register after setting the CLK1 and CLK0 bits in the UiC0 registers.

disabled), all of the SUM, PER, FER and OER bits are set to “0” (no error). The SUM bit is set to “0” (no error) when all of the PER, FER and OER
bits are set to “0” (no error). Also, the PER and FER bits are set to “0” by reading the lower byte of the UiRB register.
Nothing is assigned at the bit 11 in the U0RB and U1RB registers. When write, set to "0". When read, its content is "0".
