NAME AND DESCRIPTION
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 18)
1 = CAS and CRC4 multiframe mode (see the timing in Section
18)
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 DS21Q44.
