#182644 - push pop Responding to: ???'s previous message |
!!!!last pushed register/variable should be pop-ed first!!!
If Your simulator takes EA pin in account - where is connected? BTW. The sample (I've found it somewhere) below does something very similar to what I'm doing but it does work in this simulator. Mine doesn't. That code is very poor with many errors. External interrupt 0 causes changing accumulator - for example , this can be character You just sendind to LCD. External interrupt 1 calls LCD output. Believe me, LCD access in ISR can be used in extremal situations only. Dont do it! Keep ISR short !!! Long ISR can be used , but needs more care. |
