PLOPV
The path lost of pointer state (PLOPV) bit indicates the current status of the pointer
interpreter state machine. PLOPV is set to logic 1 when the state machine is in the
LOP_state. PLOPV is set to logic 0 when the state machine is not in the LOP_state.
PAISV
The path alarm indication signal state (PAISV) bit indicates the current status of the pointer
interpreter state machine. PAISV is set to logic 1 when the state machine is in the
AIS_state. PAISV is set to logic 0 when the state machine is not in the AIS_state.
PLOPCV
The path lost of pointer concatenation state (PLOPCV) bit indicates the current status of the
concatenation pointer interpreter state machine. PLOPCV is set to logic 1 when the state
machine is in the LOPC_state. PLOPCV is set to logic 0 when the state machine is not in
the LOPC_state.
