When transmission is enabled, transmission starts when data is written to SCnTXB.
Continuous transmission is possible by writing data to SCnTXB again while transmission is in progress.
During a 7-bit transfer, the MSB (bit 7) is ignored.
The SCnTXF flag is set to "1" when data is written to SCnTXB, and is set to "0" at the end of transmission.
The SCnTBF flag is set to "1" when data is written to SCnTXB, and is set to "0" at the start of transmission.
