28.4.6.10 Unsecure Flash Command
The Unsecure Flash command will erase the entire P-Flash and EEPROM memory space and, if the erase
is successful, will release security.

FCCOB Parameters
0x0B
Not required
Upon clearing CCIF to launch the Unsecure Flash command, the Memory Controller will erase the entire
P-Flash and EEPROM 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. If the erase verify is not
successful, the Unsecure Flash operation sets MGSTAT1 and terminates without changing the security
state. During the execution of this command (CCIF=0) the user must not write to any Flash module
register. The CCIF flag is set after the Unsecure Flash operation has completed.
