ESCRIPTION
This function queries and returns the arm count for the EX1629. This count represents the number of times the
EX1629 will wait for ARM events to occur after the trigger state machine leaves the IDLE layer. Trigger counts
should be kept in mind when considering this trigger state machine. If the state machine is configured with both arm
and trigger counts set greater than one, then, after an ARM event is received, the state machine will go through all
trigger counts before returning to the ARM layer to wait for the next ARM event.
