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
Found these off another posting That would be the documents commonly referred to as the "bible" for the 8051: Chapter 1 - 80C51 Family Architecture: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_ARCH_1.pdf Chapter 2 - 80C51 Family Programmer's Guide and Instruction Set: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_PROG_GUIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_HARDWARE_1.pdf
for Fx, I would recommend this one as well: The PCA cookbook http://www.intel.com/design/mcs51/applnots/270609.htm Erik
