If SSS bit is set to "0", the serial I/O starts sending data one transfer clock cycle after the transmission enable condition is met.
If SSS bit = 1, the serial I/O starts sending data at the rising edge (Note 1) of RxD2
1: The falling edge of RxD2 when the IOPOL is set to "0"; the rising edge of RxD2 when the IOPOL is set to "1".
2: The transmit condition must be met before the falling edge (Note 1) of RxD.
