9. Both Software ID Exit operations are equivalent
10. 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”). Valid Word-Addresses for Sec ID are from 000000H-000007H and
000010H-000017H.
