FBLANK — FLASH Verified as All Blank (Erased) Flag
4.6.6
Only five command codes are recognized in normal user modes as shown in
Section 4.4.3, “Program and Erase Command
programming and erase operations.
All other command codes are illegal and generate an access error.
It is not necessary to perform a blank check command after a mass erase operation. Only blank check is
required as part of the security unlocking mechanism.
Freescale Semiconductor
FBLANK is set automatically at the conclusion of a blank check command if the entire FLASH array
was verified to be erased. FBLANK is cleared by clearing FCBEF to write a new valid command.
Writing to FBLANK has no meaning or effect.
1 = After a blank check command is completed and FCCF = 1, FBLANK = 1 indicates the FLASH
0 = After a blank check command is completed and FCCF = 1, FBLANK = 0 indicates the FLASH
array is completely erased (all $FF).
