Dear Friends
Hello, I am writing code for external interrupt to wake up the processor. But when processor goes in power down mode and interrupt occurs it does not goes into ISR Any solution???????
Start by telling what processor. Then continue by telling us what your code looks like. We just can't (or don't want to) hack your computer to take a look...
Next thing - you say procesor doesn't go into ISR. So what _does_ the processor do?
By the way - are you writing code, or have you written the code?
