I have accidently code protected two 16F877's and dont know how to disable code protection. I am using Tony Nixons Micro Pro Programer And Rom Zap. I thought of programing code into Rom Zap and hard wiring to the F877 to disable code protection. Page 10 of Microchips Data Sheet DS30925B explains how to disable code protection but I am Not experienced enough to Write the code to enable the chip to enter a load Command and then the configuration commands. I would appreciate any help and ideas .
