Problems with VP-280 & M48T18 Timekeeper Reply

 Hi Guys,
I am trying to duplicate a Timekeeper M48T18 chip. A working original chip has time data between 1FF8h and 1FFF. I can see this in the dump that i have taken from the original.

I have read the complete image from the original chip, however obviously want to write only up to (and not including) 1FF8h. I have set the device end address to 1FF7, however every time it overwrites the values currently in 1FF7 - 1FFF.

Any advice??

Thanks
Paul
