there's no much reason in storing/restoring EA in an ISR, as EA's state is known: it must have been set if the interrupt occured
I have done so for ages, but, of course, you are right. Now, I am very much against ANY fiddeling with EA except for atomicity/flash write issues (which both should be outside an ISR). Erik |
