Safe usage of PBP commands within ASM ISR

[sougata]

If you do do it. Don't post the code. People don't understand the problem and try to do the same thing, creating huge problems.

Well Darrel that is an important piece of suggestion. I am quite comfortable with assembler and the whole point is making the ISR more readable to PBPonly users. So the whole purpose gets lost when the code is lifted and messed around in other apps.

P.S. : That also means that I have to SHAMELESSLY ask for asm versions of your other routines.
