This register is used to enable pointer event interrupts.
NDFE:
When a logic one is written to the NDFE interrupt enable bit position, a
change in active offset due to the reception of an enabled NDF (NDF_enabled
indication) will activate the interrupt out, INTB.
PSEE:
When a logic one is written to the PSEE interrupt enable bit position, a
positive pointer adjustment event will active the interrupt output, INTB.
NSEE:
When a logic one is written to the NSEE interrupt enable bit position, a
negative pointer adjustment event will activate the interrupt output, INTB.
ILLPTRE:
When a logic one is written to the ILLPTRE interrupt enable bit position, an
illegal pointer will activate the interrupt output, INTB.
INVNDFE:
When a logic one is written to the INVNDFE interrupt enable bit position, an
invalid NDF code will activate the interrupt output, INTB.
DISCOPAE:
When a logic one is written to the DISCOPAE interrupt enable bit position, a
change of pointer alignment event will activate the interrupt output, INTB.
