Ahhh, alright. So any addresses passed will be

S#######b

Where S is bit 5 from the status register, and the rest are what it's set
to? And I take it only the instructions are affected... but at the moment,
I only need to switch banks for setting up the IO... Can't we just do a
movf $85, %xxxxxxxx???

Is there a document describing, or can you tell me,  the bits in the
special registers, like status, and option? I went through the 16C84 PDF
but find nada, same with MPLAB and MPASM files.

And I was going through some more code today, and found some interupt
stuff. What I understand (for the 16C84) is that the chip powers on (or
resets?) at 0x00, and those first 4 bytes usually have a GOTO in them, and
then at 0x04, that's the interupt timer?

Thanks
