#59941 - RE: It does re-occur Oleg... Responding to: ???'s previous message |
nope and never, just an example:
INT0_ISR: CLR EX0 RETI This way we disable external interrupt, and so even TF0 is still set, nevertheless no following INT0 interrups will be occured as long as user does not set EX0 back. Is it clean? NO, If you clear the enable in the ISR, you need to set it again or you will have a mess. If an X0 interrupt occur while EX0 is clear the ISR will be executed as soon as you set EX0 Erik |
