values for the Program Once command range from 0x0000 to 0x0007. During execution of the Program

27.4.2.8
Erase All Blocks Command
The Erase All Blocks operation will erase the entire P-Flash and D-Flash memory space including the EEE
nonvolatile information register.
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.
