5.7 Serial Interface
There is one on-chip serial interface channel synchronous with the clock.
The serial interface channel 2 operates in the following two modes:
3-wire serial I/O mode
Asynchronous serial interface (UART) mode : On-chip dedicated baud rate generator
: Starting bit MSB/LSB switching possible
