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.
Example 4: Enable again in a permanent way Access and Debug Protection, after having
disabled them.
PEN0*/
Disable and re-enable of Access and Debug Protection in a permanent way (as shown by
examples 3 and 4) can be done for a maximum of 16 times.

To perform a Word Program operation during Erase Suspend, firstly bits SUSP and
SER must be reset, then bit WPG and WMS can be set.
To resume the Sector Erase operation bit SER must be set again.
In any case it is forbidden to start any write operation with SUSP bit already set.
