RPSLMV:
The RPSLMV bit reports the match/mismatch status between the expected and the accepted
path signal label.
When PSLMODE is low, RPSLMV is a logic one when the accepted PSL results in a
mismatch with EPSL[7:0]. RPSLMV is a logic zero when the accepted PSL results in a
match with the expected PSL.
When PSLMODE is high, PSLMV is a logic one when the received PSL differs from
EPSL[7:0]. PSLMV is a logic zero when the accepted PSL matches the expected PSL.
RPSLMI:
The RPSLMI bit is a logic one when the match/mismatch status between the accepted and
the expected path signal label changes state. This bit is cleared when this register is read.
RPSLUV:
The RPSLUV reports the stable/unstable status of the path signal label in the receive
stream. RPSLUV is a logic one when the current received C2 byte differs from the previous
C2 byte for five consecutive frames. RPSLUV is a logic zero when the same PSL code is
received for five consecutive frames.
RPSLUI:
The RPSLUI bit is a logic one when the stable/unstable status of the path signal label
changes state. This bit is cleared when this register is read.
