Hi Folks, I'm just finishing off my Programmer here and I am having a couple of problems. 1. I would like to do a Bulk Erase of the 16C84's Program Memory. I execute the commands: PowerUp() ; Bring Vpp and Vdd up to the Correct Levels CmdSEND( 9 ) ; Bulk Erase Program Memory CmdSEND( 8 ) ; Start Programming Wait10ms() ; Wait for the Command to Take (Actually 100 ms) PowerDn() ; Drop Vpp and Vdd 2. I inadverntently programmed a 16C84 with the CP Bit On - What is the correct way to turn it off? I have tried writing the configuration fuses with 0x03FFF, but with no luck. How is the Code Protect taken off? I can program both EPROM and Flash parts without any problems, so I suspect the problems lie in something that I'm not doing correctly.
