Sorry, I typically keep this on hand, but can't find it. I'm looking for a link to the standard Intel pdf document that details everything about the generic 51FX part. I believe it even includes the instruction set breakdown, etc. Many thanks. R. Wey
for Fx, I would recommend this one as well: The PCA cookbook http://www.intel.com/design/mcs51/applnots/270609.htm Erik
