DESCRIPTION

22       This feature is not supported in many NAND parts. 'Micron' NAND parts
23       do have this feature, but it allows only to lock all blocks, not for
24       specified range for block. Implementing 'lock' feature by making use of
25       'unlock', for now.
26
27       Returns lock status.
