4.3.4 Block Control
The block number rule for ISO/IEC1443-4 I-block is given in Table 4-14. The block control rule and whether to
be supported by this RFID are shown in Table 4-15.

Rule
Set the initial value of reader/writer block number to 0 whenever activating RFID.
When I-block or R(ACK) block whose block number is equal to the current one is
received, toggle the current block number before sending the block number to
RFID.
Set the initial value of RFID block number to 1 whenever activating RFID.
When I-block is received, toggle the current block number before sending the
block.
When R(ACK) block whose block number is not equal to the current one is
received, RFID toggles the current block number before sending the block. When
R(NAK) is received, do not toggle the block number.

By this RFID
Send the first block from reader/writer.
When I-block indicating chaining is received, send an affirmative
response to the block, with R(ACK) block.
S-block is used only for pair. Send a response to S(...)block
whenever S(...)block is requested.
When an illegal block is received or FWT timeout occurs, send
R(NAK) block (except while RFID is in chaining or when
S(DESELECT) is executed).
When an illegal block is received or FWT timeout occurs while
RFID is in chaining, send R(ACK) block.
When R(ACK) block is received and its block number is not equal
to the block number of reader/writer, re-send the last I-block.
When R(ACK) block is received and its block number is equal to
the block number of reader/writer, continue chaining.
When a response to S(DESELECT) is not sent with no error,
re-send S(DESELECT) or ignore the RFID.
RFID can send S(WTX) block, instead of I-block or R(ACK) block.
When I-block not indicating chaining is not received, send an
affirmative response.
When R(ACK) or R(NAK) block is received and its block number
is equal to the block number of RFID, re-send the last I-block.
When R(NAK) block is received and its block number is not equal
to the block number of RFID, send R(ACK).
When R(ACK) block is received and its block number is not equal
to the block number of RFID and RFID is in chaining, continue
chaining.
