Bit 7/Transmit Time Slot 0 Pass-Through (TFPT)
0 = CRC4 disabled
1 = CRC4 enabled
0 = do not force TCHBLK high during bit 1 of time slot 26
1 = force TCHBLK high during bit 1 of time slot 26
0 = HDB3 disabled
1 = HDB3 enabled
0 = normal operation
1 = force time slot 16 in every frame to all ones
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 0)
0 = transmit data normally
1 = transmit an unframed all-ones code at TPOSO and TNEGO
0 = time slot 16 determined by the SSIEx registers and the THSCS function in the PCPR register
1 = source time slot 16 from TS1 to TS16 registers
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
