2.3.5 Read Multiple Blocks (Command Code 0x23)
The Read Multiple Blocks command is an optional command that requests more than one block of user
memory data from a VICC at a time, with the first block number and the number of blocks specified in the
request. This command can be sent as an addressed or unaddressed request. If the Option_flag is set in
the request, the VICC also will return the block security status, followed by the block value, sequentially.
To perform Read Multiple Blocks using the GUI (after connecting) the user should:
1. Select the radio button for Read Multiple Blocks
2. Select Tag Flags accordingly (see Figure 10 for one example)
3. Click Set Protocol.
4. Enter First Block number to be read
5. Enter number of blocks to be read (n-1)
6. Place tags or transponders near enough to the TRF7970A EVM antenna to be read.
7. Click Execute
