I have read the "Bible", but all I get is when you enable an interrupt (i.e. SETB IE.0), the controller runs the ISR when an interrupt is invoked (when a falling edge is detected in this case). After executing RETI, it returns to the place where it was interrupted.
If I don't disabled it, the controller will run ISR whenever a falling edge is occurred. |
