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