The Pointer Interpreter Interrupt Status Register is provided at SHPI Read/Write Address
210AH 2112H 211AH 2122H 212AH 2132H 213AH 2142H 214AH 2152H 215AH and
2162H.
NJEI
The negative pointer justification event interrupt status (NJEI) bit is an event indicator.
NJEI is set to logic 1 to indicate a negative pointer justification event. The interrupt status
bit is independent of the interrupt enable bit. NJEI is cleared to logic 0 when this register is
read.
PJEI
The positive pointer justification event interrupt status (PJEI) bit is an event indicator. PJEI
is set to logic 1 to indicate a positive pointer justification event. The interrupt status bit is
independent of the interrupt enable bit. PJEI is cleared to logic 0 when this register is read.
PLOPI
The path loss of pointer interrupt status (PLOPI) bit is an event indicator. PLOPI is set to
logic 1 to indicate any change in the status of PLOPV (entry to the LOP_state or exit from
the LOP_state). The interrupt status bit is independent of the interrupt enable bit. PLOPI is
cleared to logic 0 when this register is read.
