Post by thread:[pic]: ?pseudo? instructions

You can find descriptions of these special instructions in the documentation that came with MPLAB. Also, inside MPLAB itself is a pretty decent help file system. Look under "MPASM Help", "Instruction Sets", "14-bit Core Instructions", "12-bit/14-bit Special Instructions". --Andrew _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

> i saw some pic programs with instructions like this skpnc, skpnz ... > where can i find some infos about this??? These are wrapper macros around instructions like BTFSC STATUS, Z. Some of these are built into the assembler although not documented well. Others may be from people's private wrapper macros. I've got a whole bunch of such wrapper macros and lots of other useful macros at http://www.embedinc.com/pic. ***************************************************************** Olin Lathrop, embedded systems consultant in Devens Massachusetts (978) 772-3129, spam_OUTolinTakeThisOuTembedinc.com, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Well, since I see Olin touted his macros ;^), I guess I'll the same. I has a package of macros, call EIS (for Enhanced Instruction Set), designed to incorporate many features including automatic bank/page switching and multiple-byte operands.
