Event Pop - When a logic high is written to this bit an event is
popped off the event FIFO.
The event FIFO pop occurs as part of the interrupt process after the
event has been read in the Event_Low and Event_High registers.
Popping an event discards the event and causes the next event, if
any, to be moved to the top of the FIFO ready to be read by software
on interrupt.
