Flasheraseall Command - NXP Semiconductors freescale KV4 Series Reference Manual

14.2.6.3 FlashEraseAll command

The FlashEraseAll command performs an erase of the entire flash memory. If any flash
regions are protected, then the FlashEraseAll command will fail and return an error status
code. Executing the FlashEraseAll command will release flash security if it (flash
security) was enabled, by setting the FTFA_FSEC register. However, the FSEC field of
the flash configuration field is erased, so unless it is reprogrammed, the flash security will
be re-enabled after the next system reset. The Command tag for FlashEraseAll command
is 0x01 set in the commandTag field of the command packet.
The FlashEraseAll command requires no parameters.
