NAME AND DESCRIPTION
ODF
TCR1.7
Output Data Format.
0 = bipolar data at TPOS and TNEG.
1 = NRZ data at TPOS; TNEG=0.
TFPT
TCR1.6
Transmit Timeslot 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.
T16S
TCR1.5
Transmit Timeslot 16 Data Select.
0 = sample timeslot 16 at TSER pin.
1 = source timeslot 16 from TS1 to TS16 registers.
TUA1
TCR1.4
Transmit Unframed All 1s.
0 = transmit data normally.
1 = transmit an unframed all 1s code at TPOS and TNEG.
TSiS
TCR1.3
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).
TSA1
TCR1.2
Transmit Signaling All 1s.
0 = normal operation.
1 = force timeslot 16 in every frame to all 1s.
TSM
TCR1.1
TSYNC Mode Select.
0 = frame mode (see the timing in Section 13).
1 = CAS and CRC4 multiframe mode (see the timing in Section
13).
TSIO
TCR1.0
TSYNC I/O Select.
0 = TSYNC is an input.
1 = TSYNC is an output.
