I've found the intruction set descriptions to be generaly better in the two "Reference Manuals". The "Complete Mid-Range Reference Manual" : http://ww1.microchip.com/downloads/en/DeviceDoc/33023a.pdf Or only the instruction set chapter (PIC12F/16F) : http://ww1.microchip.com/downloads/en/DeviceDoc/31029a.pdf The "Complete PIC18C Reference Manual" : http://ww1.microchip.com/downloads/en/DeviceDoc/39500a.pdf Or only the instruction set chapter (PIC18F) : http://ww1.microchip.com/downloads/en/DeviceDoc/39531.pdf Regards, Jan-Erik. _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
