0x40020 15:12 TMUX_CNTDF2[3:0] Continuous N-Times Detect for F2 Byte. Sets the num- 0x3
ber of CNTD occurrences of a consistent F2 value in the
incoming STS-3/STM-1 (AU-4) frame. The valid range for
this register is 0x3—0xF. Invalid values will be mapped to
a value of 0x3.
11:8 TMUX_CNTDRDIP[3:0] Continuous N-Times Detect for G1[3:1] Byte. Sets the 0x3
number of CNTD occurrences of a consistent G1[3:1]
value in the incoming STS-3/STM-1 (AU-4) frame. The
valid range for this register is 0x3—0xF. Invalid values will
be mapped to a value of 0x3.
7:4 TMUX_CNTDC2[3:0] Continuous N-Times Detect for C2 Byte. Sets the num- 0x3
ber of CNTD occurrences of a consistent C2 value in the
incoming STS-3/STM-1 (AU-4) frame. The valid range for
this register is 0x3—0xF. Invalid values will be mapped to
a value of 0x3.
3:0 TMUX_CNTDJ1[3:0] Continuous N-Times Detect for J1 Byte. Sets the num- 0x3
ber of CNTD occurrences of a consistent J1 value in the
incoming STS-3/STM-1 (AU-4) frame. The valid range for
this register is 0x3—0xF. Invalid values will be mapped to
a value of 0x3.

TMUX_CTDB1SEL Continuous N-Times AUTO AIS Select. Control bit,
0
when set to a logic 1, causes TOH CNTD counters to be
reset whenever the AUTO_AIS signal is asserted.
11:8 TMUX_CNTDN1[3:0] Continuous N-Times Detect for N1 Byte. Sets the num- 0x3
ber of CNTD occurrences of a consistent N1 value in the
incoming STS-3/STM-1 (AU-4) frame. The valid range for
this register is 0x3—0xF. Invalid values will be mapped to
a value of 0x3.
7:4 TMUX_CNTDK3[3:0] Continuous N-Times Detect for K3 Byte. Sets the num- 0x3
ber of CNTD occurrences of a consistent K3 value in the
incoming STS-3/STM-1 (AU-4) frame. The valid range for
this register is 0x3—0xF. Invalid values will be mapped to
a value of 0x3.
3:0 TMUX_CNTDF3[3:0] Continuous N-Times Detect for F3 Byte. Sets the num- 0x3
ber of CNTD occurrences of a consistent F3 value in the
incoming STS-3/STM-1 (AU-4) frame. The valid range for
this register is 0x3—0xF. Invalid values will be mapped to
a value of 0x3.
