I should read AN2594 Application note first. 1."A header field that occupies the first 16-bit half word of each page indicates the page status." 2."Each variable element is defined by a virtual address and a value to be stored in Flash memory for subsequent retrieval or update (in the implemented software both virtual address and data are 16 bits long). When data is modified, the modified data associated with the earlier virtual address is stored into a new Flash memory location. Data retrieval returns the modified data in the latest Flash memory location." To x893: Thank you for your EEPROM emulation library!

But it write start from 800F804 to 800F81C, and the AddressWrite are same(0x10 like a data), like this: 800F800 : 0000 0003 800F804 : 0000 0010 800F808 : 0001 0010 800F80C : 0002 0010 800F810 : 0003 0010 800F814 : 0004 0010 800F818 : 0005 0010 800F81C : 0006 0010 When DataWrite increase to 0x7 or more, the result seems to be lost: Page 0 Top Page 1 800F800 : 0000 0003 800FC00 : FFFF FFFF 800F804 : 0000 0010 800FC04 : FFFF FFFF 800F808 : 0001 0010 800FC08 : FFFF FFFF 800F80C : 0002 0010 800FC0C : FFFF FFFF 800F810 : 0003 0010 800FC10 : FFFF FFFF 800F814 : 0004 0010 800FC14 : FFFF FFFF 800F818 : 0005 0010 800FC18 : FFFF FFFF 800F81C : 0006 0010 800FC1C : FFFF FFFF Page 0 Bottom Page 1 800FBE0 : FFFF FFFF 800FFE0 : FFFF FFFF 800FBE4 : FFFF FFFF 800FFE4 : FFFF FFFF 800FBE8 : FFFF FFFF 800FFE8 : FFFF FFFF 800FBEC : FFFF FFFF 800FFEC : FFFF FFFF 800FBF0 : FFFF FFFF 800FFF0 : FFFF FFFF 800FBF4 : FFFF FFFF 800FFF4 : FFFF FFFF 800FBF8 : FFFF FFFF 800FFF8 : FFFF FFFF 800FBFC : FFFF FFFF 800FFFC : FFFF FFFF What's the virtual address really mean?
