The controller returns with the RPL flag set. A separate complete
message is sent by the controller with CPL flag set as soon as the
erasure operation has been completed. If the erasure failed the complete
message comes with ERR flag set and an error code is passed in bits
15:00 of the complete message.
On error the RPL, CPL and ERR flags are set and an error code is
passed in bits 15:00 of the reply word.
Notes:
Absolutely caution should be given when executing this command. Use
makes sense only if a new firmware binary is available that is
downloaded to the firmware flash ROMs with the command
CMDIMR_FLASH_WRITE after erasing.
The board is no more
functional, if a hardware reset occurred while or after erasing.
The host may use any port ID that is valid for the corresponding board
when calling the flash ROM erasure command. It is not necessary to
open the port used before.
