Output Data Format.
0 = bipolar data at TPOSO and TNEGO
1 = NRZ data at TPOSO; TNEGO=0
Transmit Time Slot 0 Pass Through.
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
Transmit Time slot 16 Data Select.
0 = sample time slot 16 at TSER pin
1 = source time slot 16 from TS0 to TS15 registers
Transmit Unframed All Ones.
0 = transmit data normally
1 = transmit an unframed all one’s code at TPOSO and TNEGO
Transmit International Bit Select.
0 = sample Si bits at TSER pin
1 = source Si bits from TAF and TNAF registers (in this mode, TCR1.6
must be set to 0)
Transmit Signaling All Ones.
0 = normal operation
1 = force time slot 16 in every frame to all ones
TSYNC Mode Select.
0 = frame mode (see the timing in Section 18.2)
1 = CAS and CRC4 multiframe mode (see the timing in Section 18.2)
TSYNC I/O Select.
0 = TSYNC is an input
1 = TSYNC is an output
