Hello All I have a 16F874 and I would like to download it's target firmware using = a PicStart Plus. I have read Microchip's Technical Brief TB016 on Implementing ICSP on = 16F87X parts, I have been a good boy and searched the piclist archives and discovered = that there may be an issue with the status of pin RB3 when programming, but otherwise it = seems straightforward. I am using the CC5x C compiler within MPLAB and I am just downloading an = empty main program in order to prove the ICSP link. The error that I am getting says that the configuration bits are not = being set. Can anyone think=20 of a reason for this or where I may be going wrong? Any suggestions greatly appreciated!
