Bit 0/Transmit CRC4 Enable (TCRC4). 0 = CRC4 disabled

1 = CRC4 enabled

Bit 1/Transmit G.802 Enable (TG802). See Functional Timing Diagrams for details. 0 = do not force TCHBLK high during bit 1 of timeslot 26

1 = force TCHBLK high during bit 1 of timeslot 26

Bit 2/Transmit HDB3 Enable (THDB3). 0 = HDB3 disabled

1 = HDB3 enabled

Bit 3/Transmit Signaling All Ones (TSA1). 0 = normal operation

1 = force timeslot 16 in every frame to all ones

Bit 4/Transmit International Bit Select (TSiS). 0 = sample Si bits at TSER pin

1 = source Si bits from TAF and TNAF registers (in this mode, E1TCR1.7 must be set to zero)

Bit 5/Transmit Unframed All Ones (TUA1). 0 = transmit data normally

1 = transmit an unframed all one’s code at TPOSO and TNEGO

Bit 6/Transmit Timeslot 16 Data Select (T16S). See Transmit Signaling for details

0 = timeslot 16 determined by the SSIEx registers and the THSCS function in the PCPR register 1 = source timeslot 16 from TS1 to TS16 registers

Bit 7/Transmit Timeslot 0 Pass Through (TFPT).

0 = FAS bits/Sa bits/Remote Alarm sourced internally from the TAF and TNAF registers 1 = FAS bits/Sa bits/Remote Alarm sourced from TSER
