Relation between addresses and pages in flash

[angel]

Hi Nordic,

I am trying to figure out the relation between a certain page number (say, 0xFE) and the group of addresses that it contains. How can I get this relation?

Thanks!

All values in decimal.

If the page size is Y bytes then Page number X will contain all the addresses from

X * Y to ((X+1) * Y )- 1

inversely

address Z belongs to Page number Z/Y which is an integer (equals 0 if Z < Y)

If in this case (nRF51422), PAGE_SIZE = 1024 (0x400), page 0xFE would have the addresses from 0x3F800 to 0x3FBFF, correct?

That is correct
