Example (when reading receive buffer register):
Example (when reading transmit buffer register):
When reading data from the UiRB (i = 0 to 2) register either in the clock synchronous serial I/O mode or in the
clock asynchronous serial I/O mode. Ensure the data is read 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 the clock asynchronous serial I/O mode with 9-bit transfer data
length, write data to the high-order byte first then the low-order byte, in 8-bit units.
