LRIS2K block security
The LRIS2K provides a special protection mechanism based on passwords. Each memory
block of the LRIS2K can be individually protected by one out of three available passwords,
and each block can also have Read/Write access conditions set.
Each memory block of the LRIS2K is assigned with a Protect Status area including a Block
Lock bit, two Password Control bits and two Read/Write protection bits as shown in
Table 4
Read Single Block command with the Option_flag set to ‘1’, and the Get Multiple Block
Security status command.
Table 3.

When the Block Lock bit is set to ‘1’, for instance by issuing a Block Lock command, the 2
