4.5.15 Get Multiple-Block Security Status (Get Mult_Blk Sel Status)
The Get Multiple-Block Security Status (Get Mutt. Blk. Sel Status) command gets a block
security status byte for each block requested. This byte encodes the write protection of the
block specified (e.g., unlocked, (user/factory) locked, etc.).
To get multiple block security status, the user should:
Step 1: Click the button for Get Mult.Blk.Sel Status in the Commands window
Step 2: Click on any flags that must be set in the Tag Flags window
Step 3: Optionally select a tag from the UID pulldown list in the Tag Data window (if only
one tag is present, only one choice is available)
Step 4: Enter two hex digits corresponding to the starting block number in the (First)
Block Number field in the Tag Data window. The blocks are numbered from 00
to FF (0 to 255)
Step 5: Enter two hex digits corresponding to the number of blocks to be written in the
Number of Blocks field in the Tag Data window. The number of blocks in the
request is one less than the number of blocks that the tag returns in its response
E.g., a value of 06 in the Number of Blocks field requests to read 7 blocks. A
value of 00 requests to read a single block
Step 6: Execute the command Step 0:
