Hi 

The WIN register determines the earliest time that a refresh sequence is considered valid. The WIN register value must be less than the TOVAL register value.
I don't see a particular limitation other than the above.

Hi Robin

Only requirement is WIN value should be less than TVOL value right. There is no specific range for WIN value.

Thanks for your support
