Hi,
I'm having a problem while interfacing a 89c52 with a 24c65 NVRAM
It is used for a datalogger application.
I have divided my 24c65 into 4 arrays of 2kB each

[0000h-07FFh] = array0
[0800h-0FFFh] = array1
[1000h-17FFh] = array2
[1800h-1FFFh] = array3

So, if I write data to array 0 or 1. everything is ok, it is written
perfectly, and I can read it again too.
BUT: if I write to array2 or 3, the data doesn't get to the 24c65
I can read the data though, but it isn't the data I wrote to it.
I always use the same routines to write something to the 24c65.
So my guess is that I have to change something to my writecycle once the
adress is 1000h or above.
I can't seem to find anything in the datasheets though.
does anybody have an idea??
greetz,
