Figure 25-2. Algorithm for Randomly Modifying Data
Notes:
MAIN MEMORY PAGE PROGRAM
1. To preserve data integrity, each page of an Atmel DataFlash sector must be updated/rewritten at least once within
2. A Page Address Pointer must be maintained to indicate which page is to be rewritten. The Auto Page Rewrite com-
3. Other algorithms can be used to rewrite portions of the Flash array. Low-power applications may choose to wait
every 10,000 cumulative page erase and program operations
mand must use the address specified by the Page Address Pointer
until 10,000 cumulative page erase and program operations have accumulated before rewriting all pages of the
sector. See application note AN-4 (“Using Atmel’s Serial DataFlash”) for more details
