-There are some things to notice

-

-* AT91SAM7S64 is tested

-* All AT91SAM7Sxx  and  AT91SAM7Xxx should work but is not tested

-* All parameters are identified from onchip configuartion registers 

-*

-* The flash controller handles erases automatically on a page (128/265 byte) basis

-* Only an EraseAll command is supported by the controller

-* Partial erases can be implemented in software by writing one 0xFFFFFFFF word to 

-* some location in every page in the region to be erased

-*  

-* Lock regions (sectors) are 32 or 64 pages

+There are some things to notice
+
+* AT91SAM7S64 is tested
+* All AT91SAM7Sxx  and  AT91SAM7Xxx should work but is not tested
+* All parameters are identified from onchip configuartion registers 
+*
+* The flash controller handles erases automatically on a page (128/265 byte) basis
+* Only an EraseAll command is supported by the controller
+* Partial erases can be implemented in software by writing one 0xFFFFFFFF word to 
+* some location in every page in the region to be erased
+*  
+* Lock regions (sectors) are 32 or 64 pages
