immediately before returning from the service routine, or if
the AEOI (Automatic End of Interrupt) bit is set, until the trail-
ing edge of the last INTA. While the IS bit is set, all further
interrupts of the same or lower priority are inhibited, while
higher levels will generate an interrupt (which will be
acknowledged only if the microprocessor internal interrupt
enable flip-flop has been re-enabled through software).
After the initialization sequence, IR0 has the highest priority
and IR7 the lowest. Priorities can be changed, as will be
explained in the rotating priority mode or via the set priority
command.
