Keep in mind, however, that the polarity of the PWRTE configuration bit is different between the 'C84 and the 'F84... When you program a 16C84 with MPLAB configured for the 16F84, you'll need to set the PWRTE to the OPPOSITE value of the one you want. -Andy === Andrew Warren - fastfwd@ix.netcom.com === Fast Forward Engineering, Vista, California === http://www.geocities.com/SiliconValley/2499
