Chapter 26 384 KByte Flash Module (S12XFTM384K2V1)
values for the Program Once command range from 0x0000 to 0x0007. During execution of the Program
Once command, any attempt to read addresses within P-Flash block 0 will return invalid data.
26.4.2.8
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.

1. 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.
