31.4.6.10 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.
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.
31.4.6.11 Verify Backdoor Access Key Command
The Verify Backdoor Access Key command will only execute if it is enabled by the KEYEN bits in the
FSEC register (see
user-supplied keys match those stored in the Flash security bytes of the Flash configuration field (see
