= 63 00h if there is no more retry chance
Note: After SW1SW2 = 0x9000h has been received, read back the data in Application Zone can
check whether the ERASE_APPLICATION_ZONE_WITH_ERASE is correct. If all data in
Application Zone is erased and equals to “0xFFh,” the previous verification is success.
