This register allows identification and acknowledgment of pointer event interrupts.
NDFI:
The NDFI bit is set to logic one when the RPOP detects an active NDF event to a valid
pointer value. NDFI is cleared when the RPOP Pointer Interrupt Status register is read.
PSEI:
The PSEI bit is set to logic one when the RPOP detects a positive stuff event. PSEI is
cleared when the RPOP Pointer Interrupt Status register is read.
NSEI:
The NSEI bit is set to logic one when the RPOP detects a negative stuff event. NSEI is
cleared when the RPOP Pointer Interrupt Status register is read.
ILLPTRI:
The ILLPTRI bit is set to logic one when the RPOP detects an illegal pointer event. ILLPTRI
is cleared when the RPOP Pointer Interrupt Status register is read.
INVNDFI:
The INVNDFI bit is set to logic one when the RPOP detects an invalid NDF event. INVNDFI
is cleared when the RPOP Pointer Interrupt Status register is read.
DISCOPAI:
The DISCOPAI bit is set to logic one when the RPOP detects a discontinuous change of
pointer. DISCOPAI is cleared when the RPOP Pointer Interrupt Status register is read.
