 +===== Notes =====
 +  *No other registers are used.
 +  *There are eight possible events 0 to 7 represented by the bits in D2.B. The job can be asked to wait for any combination of these. For example the job will wait for events 0 and 2 if D2.B is 5.
 +  * The job will have an event accumulator set up to record the events for which it is waiting. When an event is received it is removed from the accumulator.
