Well said. This is from pp.239-249 of the datasheet. http://www.microchip.com/download/lit/pline/picmicro/families/18fxx20/39609b.pdf >And this is the configuration: >Config1 = 2500 Main oscillator is source FOSC2 and FOSC0 set => EC oscillator w/ OSC2 as RA6 >Config2 = 000F Brownout reset enabled, powerup timer disabled >Config3 = 0080 WAIT set, Extended Microcontroller mode CCP2 I/O multiplexed with RE7 >Config4 = 0081 Debugger disabled. RB6:7 are GPIO Low voltage ICSP disabled Stack full/underflow causes reset >Config5 = C0FF Data EEPROM not code-protected Boot block not code protected Blocks 0-7 not code protected >Config6 = E0FF Blocks 0-7 not write protected Data EEPROM not write protected Boot block not write protected Config registers not write protected >Config7 = 40FF Blocks 0-7 not protected from table reads executed in other blocks Boot block not protected from tabler reads executed in other blocks >ID Value = 0123456789ABCDEF In the datasheet it looks like the ID register is only two bytes. Not sure what you mean here. I don't think it really matters what goes there though if you aren't using it in your app. Nick -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
