RxSIGC[1:0]]
R/W

Signaling conditioning [1:0]
These bits allow user to select the format of signaling substitution on
a per-channel basis, as presented in the table below.
1-0
RxSIGE[1:0]
R/W
00
Receive Signaling Extraction [1:0]
These bits control per-channel signaling extraction as presented in
the table below. Signaling information can be extracted to the
Receive Signaling Array Register (RSAR), the Receive Signaling
Output pin (RxSIG_n) if the Receive SIgnaling Interface is enable,
or the Receive Overhead Interface output (RxOH_n) if OH_ENB bit
is enabled. (bit 5 of this register).

Substitutes all signaling bits with one.
01
Enables 16-code (A,B,C,D) signaling substi-
tution.
Users must write to bits 3-0 in the Receive Sig-
naling Substitution Register (RSSR) to provide
the 16-code (A,B,C,D) signaling substitution val-
ues.
10
Enables 4-code (A,B) signaling substitution.
Users must write to bits 4-5 in the Receive Sig-
naling Substitution Register (RSSR) to provide
the 4-code (A,B) signaling substitution values.
11
Enables 2-code (A) signaling substitution.
Users must write to bit 6 in the Receive Signal-
ing Substitution Register (RSSR) to provide the
2-code (A) signaling substitution values.

Enables 4-code (A,B) signaling extraction
Only signaling bits A,B will be extracted.
11
