#93017 - AN-461 Responding to: ???'s previous message |
Have you checked AN-461 ? It's all there. Also you need check the errata, there is something there as well.
OPf course, if you use RC reset all bets are off. Also, brand new chips are alrteady in ISP mode, no "funny levels" required, so if you have a problem programming a brand new chip it is your serial connection that is faulty. Erik PS: when you get it going install NoTouch and save the aggrevation. |
