I have some trouble with the EEPROM.
When I write or read from it at the start of the program then it works.
But when I do some instructions on the I/O-Ports before, it mostly, not
always does read or write wrong values.

For I/O-Ports I use something like
bsf	GPIO,0

I know that the bits 6-7 of GPIO are used for the EEPROM and that bsf
does also read those and output what it has read. Therefore I can
understand that proplems can happen, but there is nothing written about
it in Microchips documentation.

Did anyone experience a similar problem or has an idea how to solve it?

I use MPLAB 5.00 and fl51xinc.asm.
