5. Valid Byte Addresses for Sec ID are from 000000H-00000FH and 000020H-00002FH.
6. The device does not remain in Software Product ID Mode if powered down.
7. With A

8. Both Software ID Exit operations are equivalent
9. If users never lock after programming, Sec ID can be programmed over the previously unprogrammed bits (data=1) using the Sec ID
mode again (the programmed “0” bits cannot be reversed to “1”).
