I have no idea what the packet driver does but to your
original question yes, you can freely modify registers'
values passed to the interrupt procedure and new values will
have effect upon return, just like help says, and see the
attached example.
No, it doesn't matter whether you use SetIntVec or change
interrupt table by hand (though I'd not recommend the latter).
Best regards,
