Bits 0 to 4 / Transmit HDLC Channel Select (THCS0 to 4).
Determines which DSO channel will have the carry
the HDLC message if enabled.
Bit 5 / Transmit HDLC Controller Enable (THCEN)
0 = Transmit HDLC Controller is not enabled
1 = Transmit HDLC Controller is enabled
Bit 6 / Unused
Bit 7 / Transmit Abort (TABT).
A 0-to-1 transition will cause the FIFO contents to be dumped and one FEh abort to
be sent followed by 7Eh or FFh flags/idle until a new packet is initiated by writing new data into the FIFO. Must be
cleared and set again for a subsequent abort to be sent.
