Get Multiple Block Security Status
When receiving the Get Multiple Block Security Status command, the M24LR16E-R sends
back the sector security status. The blocks are numbered from 00h to 01FFh in the request
and the value is minus one (–1) in the field. For example, a value of '06' in the “Number of
blocks” field requests to return the security status of seven blocks.
The Protocol_extension_flag should be set to 1 for the M24LR16E-R to operate correctly. If
the Protocol_extension_flag is at 0, the M24LR16E-R answers with an error code.
During the M24LR16E-R response, if the internal block address counter reaches 01FFh, it
rolls over to 0000h and the Sector Security Status bytes for that location are sent back to the
reader.
