NAME AND DESCRIPTION
ODF
TCR1.7
Output Data Format.
0 = bipolar data at TPOSO and TNEGO
1 = NRZ data at TPOSO; TNEGO=0
TFPT
TCR1.6
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
T16S
TCR1.5
Transmit Time slot 16 Data Select.
0 = sample time slot 16 at TSER pin
1 = source time slot 16 from TS0 to TS15 registers
TUA1
TCR1.4
Transmit Unframed All Ones.
0 = transmit data normally
1 = transmit an unframed all one’s code at TPOSO and TNEGO
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 Ones.
0 = normal operation
1 = force time slot 16 in every frame to all ones
TSM
TCR1.1
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)
TSIO
TCR1.0
TSYNC I/O Select.
0 = TSYNC is an input
1 = TSYNC is an output
Note: See Figure 18-15 for more details about how the Transmit Control Registers affect the
operation of the DS21354/DS21554.
