When transmission is enabled, transmission starts when data is written to SC0TXB.
Continuous transmission is possible by writing data to SC0TXB again while transmission is in progress.
During a 7-bit transfer, the MSB (bit 7) is ignored.
The SC0TXF flag is set to "1" when data is written to SC0TXB, and is set to "0" at the end of transmission.
The SC0TBF flag is set to "1" when data is written to SC0TXB, and is set to "0" at the start of transmission.
