Hello Could anyone please explain how to use the _Config in HI-TECH PICC, I have tried every combination and I keep getting syntax errors. All I want is to set a 16F84 with XTOSC, No watchdog and no protection, And the same for a 16F877 with normal programming enabled and nothing else. I have asked the question on the HI-Tech mailing list with no replies. Thankyou Les les@top204.freeserve.co.uk
