allowed to execute again on that same phrase.

11.3.10.7 Erase All Blocks command

The Erase All Blocks operation will erase the entire flash memory space.
Table 11-23. Erase All Blocks command FCCOB requirements
CCOBIX[2:0]
000
Upon clearing FSTAT[CCIF] to launch the Erase All Blocks command, the memory
controller will erase the entire NVM memory space and verify that it is erased. If the
memory controller verifies that the entire NVM memory space was properly erased,
security will be released. Therefore, the device is in unsecured state. During the execution
of this command (FSTAT[CCIF] = 0) the user must not write to any NVM module
register. The FSTAT[CCIF] flag will set after the erase all blocks operation has
completed.
