Bit 7: Transmit Bit 8 Suppress (TBSE8). MSB of the channel. Set to one to stop this bit from being used.
Bit 6: Transmit Bit 7 Suppress (TBSE7). Set to one to stop this bit from being used.
Bit 5: Transmit Bit 6 Suppress (TBSE6). Set to one to stop this bit from being used.
Bit 4: Transmit Bit 5 Suppress (TBSE5). Set to one to stop this bit from being used.
Bit 3: Transmit Bit 4 Suppress (TBSE4). Set to one to stop this bit from being used.
Bit 2: Transmit Bit 3 Suppress (TBSE3). Set to one to stop this bit from being used.
Bit 1: Transmit Bit 2 Suppress (TBSE2). Set to one to stop this bit from being used.
Bit 0: Transmit Bit 1 Suppress (TBSE1). LSB of the channel. Set to one to stop this bit from being used.

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.
Bit 6: Send BOC (SBOC) (T1 Mode Only). Set = 1 to transmit the BOC code placed in bits 0 to 5 of the
register.
Bit 5: Transmit HDLC Controller Enable (THCEN).
Bits 4 to 0: Transmit HDLC Channel Select (THCS[4:0]). Determines which DSO channel will carry the HDLC
message if enabled. Changes to this value are acknowledged only upon a transmit HDLC controller reset (THR at
THC1.5).
0 = Transmit HDLC controller is not enabled.
1 = Transmit HDLC controller is enabled.
