I see the HIP and LIP bits in the STATUS sfr are read only. Feel it's a bit of a shame!
Is there any way around this?
Re-entrant interrupt on the 80C51

Which 8051 variant is this?
Ian
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.
