Datasheet

The reserved nonvolatile information register accessed by the program once command

cannot be erased, and any attempt to program one of these phrases a second time will not

be allowed. Valid phrase index values for the program once command range from 0x0000

to 0x0007. During execution of the program once command, any attempt to read

addresses within flash will return invalid data.

Table 4-31. Program once command error handling

FSTAT

ACCERR

Set if CCOBIX[2:0] != 101 at command launch

Set if command not available in current mode (see Table 4-9)

Set if an invalid phrase index is supplied

Set if the requested phrase has already been programmed

FPVIOL None

MGSTAT1 Set if any errors have been encountered during the verify operation

MGSTAT0

Set if any non-correctable errors have been encountered during the verify

operation

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.

4.5.2.9.7 Erase all blocks command

The erase all blocks operation will erase the entire flash and EEPROM memory space.

Table 4-32. Erase all blocks command FCCOB requirements

CCOBIX[2:0] NVM_FCCOBHI parameters NVM_FCCOBLO parameters

000 0x08 Not required

Upon clearing NVM_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 (NVM_FSTAT[CCIF] = 0) the user must not write to any NVM module

completed.
