POSITION NAME AND DESCRIPTION
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
TCR1.1
TSYNC Mode Select.
0 = frame mode (see the timing in Section 19.2)
1 = CAS and CRC4 multiframe mode (see the timing in Section 19.2)
TSIO
TCR1.0
TSYNC I/O Select.
0 = TSYNC is an input
1 = TSYNC is an output
NOTE:
See Figure 19-15 for more details about how the Transmit Control Registers affect the operation of the
DS21354/554.

TCR2.6
Sa7 Bit Select. Set to one to source the Sa7 bit from the TLINK pin; set
to zero to not source the Sa7 bit. See Section 19.2 for timing details.
Sa6S
TCR2.5
Sa6 Bit Select. Set to one to source the Sa6 bit from the TLINK pin; set
to zero to not source the Sa6 bit. See Section 19.2 for timing details.
Sa5S
TCR2.4
Sa5 Bit Select. Set to one to source the Sa5 bit from the TLINK pin; set
to zero to not source the Sa5 bit. See Section 19.2 for timing details.
Sa4S
TCR2.3
Sa4 Bit Select. Set to one to source the Sa4 bit from the TLINK pin; set
to zero to not source the Sa4 bit. See Section 19.2 for timing details.
ODM
TCR2.2
Output Data Mode.
0 = pulses at TPOSO and TNEGO are one full TCLKO period wide
1 = pulses at TPOSO and TNEGO are 1/2 TCLKO period wide
AEBE
TCR2.1
Automatic E–Bit Enable.
0 = E–bits not automatically set in the transmit direction
1 = E–bits automatically set in the transmit direction
PF
TCR2.0
Function of RLOS/LOTC Pin.
0 = Receive Loss of Sync (RLOS)
