19.5 Serial Interface
(1) When reading data from the UiRB (i=0,1) register even in the clock asynchronous serial I/O mode or
(2) When writing data to the UiTB register in the clock asynchronous serial I/O mode with 9-bit transfer
Example (when reading transmit buffer register):
Example (when reading receive buffer register):
in the clock synchronous serial I/O mode. Be sure to read data in 16-bit unit. When the high-byte of
the UiRB register is read, the PER and FER bits of the UiRB register and the RI bit of the UiC1
register are set to "0".
data length, data should be written high-byte first then low-byte in 8-bit unit.
