Is it possible to write an ISR in assembly and use the dispatcher to
call it?
Or
Can you use the dispatcher and have a vectors.asm in the same program?



Lucy
You can write an assembly function cand plug it to dispatcher.

For example

.global _myFunc
_myFunc:
nop
nop
nop
nop
return

The function _myFunc can be plugged into the dispatcher.

It is recommended that you dont mix usage of dispatcher with your own
hand written ISR.

With eyes to see the sunset's glow,
With ears to hear what I would know...
Oh, God, forgive me when I whine!
I'm blessed indeed! The world is mine!
