    Hi Abdul,

    The flash content is protected from modification. There is one register called Flash Bank Protection Register (FBPROT). When bit 0 of FBPROT register is zero, which is default value, the level 1 protection is enabled which means that writing to flash sector enable register is disabled. If the flash sector is enabled, the sector can not be erased and programmed.

    You can check if the FBSE (flash bank sector enable register) is writable if the level 1 protection is enabled or disabled.
