Chapter 4 RF Communication Mode
4.2.5.7 Block List
For encrypted communication in tunnel mode, how to specify block list is slightly different from the
JISX6319-4 specification. Figure 4-11 shows the block list referenced from this RFID.
(1) Plaintext (unencrypted) communication in RF communication mode: The block number of block list can be
set freely. The RFID references to all block numbers.
(2) Plaintext (unencrypted) communication in tunnel mode: The block number of block list should be set in
ascending order. The RFID checks that the block number is set in ascending order and if not, it responds with
an error.
(3) Encrypted communication in RF communication mode or tunnel mode: The block number to access is
specified using the block numbers between first and (m-2)th in the block list. The last two block numbers are
dummy. The block number of block list should be set in ascending order. The RFID checks that the block
number is set in ascending order and if not, it responds with an error.
Note: When specifying muitiple blocks, communication mode (RF communication mode/ tunnel mode) and
encrypted communication for all blocks should be configured to the same setting; if not, the RFID
responds with an error.
Note: When setting block numbers in ascending order, set to 0x00 following the block number 0xFF (and set
to 0x01 following 0x00). Mode setting (bits 2 to 0 of byte D2) for all blocks should be set to the same
value.
