If the API is used in clock synchronous serial communication mode, do not set these
values.

For the clock polarity of serial communication, the following values can be set.
If the API is used in clock asynchronous serial communication mode, do not set these
values.
(M16C) (UART0, UART1, UART2)
RAPI_DPOL_NON Polarity not inverted RAPI_DPOL_INV Polarity inverted
(M16C) (SI/O3, SI/O4)

logic inverted.
RAPI_LOGIC_REV The value written in the transmit buffer register is inverted before
being transmitted.
