Double Word Program is always performed on the Double Word aligned on an even Word:
bit ADD2 of FARL is ignored.
Sector erase
Example: Sector Erase of sectors B0F1 and B0F0 of Bank 0 in IFlash Module.
Suspend and resume
Word Program, Double Word Program, and Sector Erase operations can be suspended in
the following way:
Then the operation can be resumed in the following way:
Before resuming a suspended Erase, FCR1H/FCR1L must be read to check if the Erase is
already completed (FCR1H = FCR1L = 0x0000 if Erase is complete). Original setup of
Select Operation bits in FCR0H/L must be restored before the operation resume, otherwise
the operation is aborted and bit RESER of FER is set.
Set protection
Example 1: Enable Write Protection of sectors B0F3-0 of Bank 0 in IFlash module.
Example 2: Enable Access and Debug Protection.
Example 3: Disable in a permanent way Access and Debug Protection.
