A86: Interrupts




OK, simple question time. What happens when you enable/disable interrupts? I'm
assuming that, in the code:

di

will enable interrupts and

ei

will enable interrupts. What happens when you do this? How many T-states does
each take? Most importantly, would it be wise or a good idea to
disable/renable interrups during "Computationally Expensive" parts of code?
