18M2 EEPROM problem...

[sefino]

Hi guys,
Sometimes I have a problem with the EEPROM in PICAXE 18M2. There is another value on specified address in integrated EEPROM memory, than stored before powering-off. This case is seen approximately one of twenty switch on... Powering it from two alkaline batteries. Know anything about that?

Von = 3,3V
fclk = 32MHz

For example:
symbol bPom1 = b2
symbol wPom1 = w13
read bPom1, word wPom1
write bPom1, word wPom1

Thanks.

You are using a variable as the 'bPom1' address so what is in that variable will determine where the data is actually read or written. It could be you are not writing data to the same place you are reading from, it could be that other data written is overwriting data previously written. It is not easy to analyse the problem without having more details of the program used.
