VT_RXSIG_CH_SEL[1—28][4:0]
Receive Output Channel Selection.
These bits
are programmed with the same value as the
cross connect for each individual channel. The
bits are
only used in byte-synchronous mode
and can be set to 0xXX for all other modes. If an
invalid value is programmed, UNEQ-V will be
transmitted in the specified channel. Invalid deci-
mal values are 0, 29, 30, and 31. See
Table 568
on page 446
.
J2 Trace Monitoring Mode Control.
See
Sec-
tion 19.11, J2 Byte Monitor and Termination
(J2MON), on page 444.
Receive Path Enhanced RDI-V Enable.
Logic 1
enables enhanced RDI-V.
Receive Demapping Mode Control.

VT_Z6_BYTE[1—28][7:0]
Received Z6/N2 Byte Value.
Accepted Z6/N2 value.
VT_OBITS[1—28][7:0]
Received O Bits Value.
Accepted overhead bits in
asynchronous and bit-synchronous modes.
VT_OBITS[7:4] are the O bits received in the byte follow-
ing J2, and VT_OBITS[3:0] are the O bits received in the
byte following Z6/N2.
