When reading data from the UiRB (i = 0 or 1) register either in clock synchronous serial I/O mode or in clock
asynchronous serial I/O mode, always read data in 16-bit units.
When the high-order byte of the UiRB register is read, bits PER and FER in the UiRB register and the RI bit in
the UiC1 register are set to 0.
To check receive errors, read the UiRB register and then use the read data.
When writing data to the UiTB register in clock asynchronous serial I/O mode with 9-bit transfer data length,
write data to the high-order byte first and then the low-order byte, in 8-bit units.
Program example to read the receive buffer register:
Program example to write to the transmit buffer register:
