This API erases the contents of the specified memory in the Serial Flash.
Note:
- The erased bytes will read as 0xFF.
-
For Intel, STM, Winbond or Spansion Serial Flash the user application must call
XIsf_WriteEnable()API by passing XISF_WRITE_ENABLE as an argument before callingXIsf_Erase()API. - Atmel Serial Flash support Page/Block/Sector Erase operations.
- Intel, Winbond, Numonyx (N25QXX) and Spansion Serial Flash support Sector/Block/Bulk Erase operations.
- STM (M25PXX) Serial Flash support Sector/Bulk Erase operations.
