The actual programming time is shortened, but that is internal to the PIC. > Question 2: Are there different registers etc that have to be set up > compared to the F84 (during programming)? Nope. The only diference, will be ROM/EEPROM size. Also, take note of the LVP pin, RB3. Keep it LOW while programming. -- Best regards Tony mICros http://www.bubblesoftonline.com mailto:sales@bubblesoftonline.com -- http://www.piclist.com#nomail Going offline?
