NAME AND DESCRIPTION
Not Assigned. Should be set to 0 when written to.
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 TS1 to TS16 registers
Transmit Unframed All Ones.
0 = transmit data normally
1 = transmit an unframed all ones code at TPOS and TNEG
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 14)
1 = CAS and CRC4 multiframe mode (see the timing in Section 14)
TSYNC I/O Select.
0 = TSYNC is an input
1 = TSYNC is an output
