Can I use the interrupt nesting?

Latest Updated:10/10/2006

Question:

Can I use the interrupt nesting?

Answer:

Yes.
Set the interrupt flag(I flag) to "1" in the interrupt routine. The interrupt with the higher priority than the processor interrupt request(IPL) at the time is accepted.(The interrupt request with the same priority as IPL isn't accepted.)
