Example (when reading receive buffer register):
Example (when reading transmit buffer register):
When reading data from the U0RB (i = 0, 1) register even in the clock asynchronous serial I/O mode
or in the clock synchronous serial I/O mode. Ensure to read data in 16-bit unit. When the high-order
byte of the U0RB register is read, the PER and FER bits in the U0RB register and the RI bit in the
U0C1 register are set to “0”.
When writing data to the U0TB register in the clock asynchronous serial I/O mode with 9-bit transfer
data length, write data high-order byte first, then low-order byte in 8-bit units.
