Safe usage of PBP commands within ASM ISR

[sougata]

Now I wrote INT in ASM.
The problem is that the device must be powered with battery for several years...
So INT must be as fastest as possible...

Depending on your application, a short wake period (Higher Fosc) may not translate into the lowest average power drain. Optimizing your code and the oscillator frequency (which may not be the shortest execution) are needed. Also while measuring current for the XLP devices try to keep the ambient temp similar. Changes in ambient temp results in current changes as I have experienced.

I didn't think on short wake period. I meant INT routines should have the smallest possible number of instructions.
For now average current consumption is about 10uA at 3V (CR2302), Pic running on INTOSC 4MHz.
