Re-entrant interrupt on the 80C51
- 05-08-2006

Re: Re-entrant interrupt on the 80C51

It's the Dallas DS80C400 part.
I've managed to do it in more a fudge like manner where I wrote an embedded
piece of assembler where I stacked a label (3 bytes for this part) and
called an RETI. That then resets the LIP bit. Shame it's read only and you
have to use this method.
