26.4.2.10 Erase P-Flash Sector Command
The Erase P-Flash Sector operation will erase all addresses in a P-Flash sector.
Upon clearing CCIF to launch the Erase P-Flash Sector command, the Memory Controller will erase the
selected Flash sector and then verify that it is erased. The CCIF flag will be set after the Erase P-Flash
Sector operation has completed.
26.4.2.11 Unsecure Flash Command
The Unsecure Flash command will erase the entire P-Flash and D-Flash 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 D-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. If the erase verify is not
successful, the Unsecure Flash operation sets MGSTAT1 and terminates without changing the security
