Read out the UiRB register in 16-bit unit.
The SUM, PER, FER and OER bits are set to “0” (no error) w hen the SMD2 to SMD0 bits in the UiMR register are set to
“000b” (serial interface disabled) or the RE bit in the U0C1 register is set to “0” (disables receive). The SUM bit is set
to “0” (no error) w hen the PER, FER and OER bits are set to “0” (no error).
The PER and FER bits are set to “0” even w hen the higher byte of the U0RB register is read out.
Write to this register w hile the serial interface is neither transmitting nor receiving.
Use the MOV instruction to w rite to this register.
When the transfer data length is 9-bit long, w rite to high-byte data first then low -byte data.
Use the MOV instruction to w rite to this register.
