64 KByte Flash Module (S12FTMRG64K512V1)
17.4.6.7
The Erase All Blocks operation will erase the entire P-Flash and EEPROM memory space.
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.
17.4.6.8
The Erase Flash Block operation will erase all addresses in a P-Flash or EEPROM block.

If a Program Once phrase is initially programmed to 0xFFFF_FFFF_FFFF_FFFF, the Program Once command will
be allowed to execute again on that same phrase.
