cleared when the RPOP Pointer Interrupt Status register is read.

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:
