Eeprom accidentally erased?

[Josuetas]

Ok, about the device i am using it´s PIC16F628A.

And i DO am using the MCLR pin as input, might that be any reason?.

By the way Melanie, why would doing CRC help any good? i would still have to reconfigure the device and this is really BAD!!!

Now i don´t know if the discussion should be open here but.. this error seems to be of the device, else microchips. Does this happen to the uC`s of other companies like ATMEL or MOTO? You guys know that none cares if it´s the device, ultimately it`s the designers fault!. If this keeps happening to me i would have to change to other brands to avoid such bothers! Wouldn´t you? We need faultyless bases to develop our devices don´t we?

I still hope this can be fixed, could some other configuration help me avoid the problem? i don`t have any extra memory outside the device and if for some reason is a stack problem i am not using any gosub... just GOTO sentences in my program.
What could be worst is that the number don´t just gets erased to FF or 00 but takes any random number wich means a different configuration for the firmware.

Could a Voltage peak at startup be the reason? i don´t get how programming works or even how LVP works (628 doesn´t have this does it?)

I will try this, maybe store the same data (it´s just one byte) in two or three different places of the memory and handle differently if they don´t match.

Thanks for your replies.
