Hi everybody Have any of you seen this problem: In the pic84, I am programming some cell in the intern EEprom and I make a power failure to the PIC. In some cases the EEprom cell kind of 'latch up' it is impossible to program the cell again after the power is on . The only found way is to program the PIC again. Has any of your tried this ?
