    Lock Bit Security Register default to 0xFF
    Setting a sector to 0x00 will protect the data in that sector from modification.

    This device has 4096 sectors, indexed 0 - 4095

    To set a Lock Bit Security Register, enter its index
    Example: To set Sector at index 13, enter 13

    To set a range, separate the low and high register indexes with a hyphen
    Example: To set Sectors at indexes 3 - 17, enter 3-17

    To specify multiple indexes or ranges, separate the indexes or ranges with a comma
    Example: To set Sectors at indexes 13, 22-27, 31-40 and 47, enter 13,22-27,31-40,47
