Chapter 11 Serial Interface 0, 1
Operation
Transmission/reception data polarity switching
In UART communication, polarity of transmission/reception data cannot be switched.
At the same time, setups of the SCnTRN, SCnREN flags of the SCnMD0 register are invalid.
Clock Setup
At UART communication, the transfer clock is not needed, but the clock setup should be needed to
decide the timing of the data transmission / reception in the serial interface.
Select the timer to be used as a baud rate timer, by the SCnCKS register, and set the SCnMST flag of
the SCnMD1 register to "1" to select the internal clock (clock master).
At UART communication, set the SCnMST flag of the SCnMD1 register to "1". If that is set to
"0", the communication is impossible.
