0005 Description:
0006 Show whether the floor (0 to 4), protection area (0 or 1) is
0007 keylocked. Each docg3 chip (or floor) has 2 protection areas,
0008 which can cover any part of it, block aligned, called DPS.
0009 The protection has information embedded whether it blocks reads,
0010 writes or both.
0011 The result is:
0012
0013 - 0 -> the DPS is not keylocked
0014 - 1 -> the DPS is keylocked
