Upon clearing CCIF to launch the Erase All Blocks command, the Memory Controller will erase the entire

Flash memory space and verify that it is erased. If the Memory Controller veriﬁes that the entire Flash

memory space was properly erased, security will be released. During the execution of this command

(CCIF=0) the user must not write to any Flash module register. The CCIF ﬂag will set after the Erase All

Blocks operation has completed.
