As far as I am aware... When interrupts are disabled, then the hardware just sets the IRQ bit... but no interrupt is thrown. Lots of depackers use this with timers, set a timer going woth IRQ's off, all that happens is the bit is set.
If you re-enable IRQ's then an interrupt will happen at once if any bits are set.
One thing I don't know, is the order.... if all timers, rasters etc.
are ALL set... whats the order??
