no. what actually happens is when the interrupt is executed (every 200th
if a second) you need to disable interrupts so no further intuerrupts
will occur untill you are finished. at the end of your interrupt routine
you should always have a
jp $0038
this calls the standard interrupt handler which checks for key
presses and such. before the standard interrupt handler returns it
reenables interrupts.
