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 TS0 to TS15 registers
TUA1
TCR1.4
Transmit Unframed All Ones
0 = transmit data normally
1 = transmit an unframed all one’s 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 Ones
0 = normal operation
1 = force timeslot 16 in every frame to all ones
TSM
CR1.1
TSYNC Mode Select
0 = frame mode (see the timing in Section 22)
1 = CAS and CRC4 multiframe mode (see the timing in
Section 22)
TSIO
TCR1.0
TSYNC I/O Select
0 = TSYNC is an input
1 = TSYNC is an output
Note: See Figure 22–15 for more details about how the Transmit Control Registers affect the operation
of the DS21Q44.
