      5Description:
      6		Show whether the floor (0 to 4), protection area (0 or 1) is
      7		keylocked. Each docg3 chip (or floor) has 2 protection areas,
      8		which can cover any part of it, block aligned, called DPS.
      9		The protection has information embedded whether it blocks reads,
     10		writes or both.
     11		The result is:
     12
     13		- 0 -> the DPS is not keylocked
     14		- 1 -> the DPS is keylocked
