Upon clearing FSTAT[CCIF] to launch the erase verify block command, the memory
controller will verify that the selected flash block is erased. The FSTAT[CCIF] flag will
set after the erase verify block operation has completed. If the block is not erased, it
means blank check failed and both FSTAT[MGSTAT] bits will be set.
