SRTAG2KL

RF command sets

Note:

Block numbering rules:

When the RF host sends a command to the SRTAG2KL the format of the payload is the C-

APDU.

When the SRTAG2KL sends a command to the RF host, the format of the payload is the R-

APDU.

Block number(1)

1. Follow ISO 14443_4 Block numbering rules (see note)

Reader rules:

Rule A: The Reader block number shall be initialized to 0.

Rule B:

When an I-block or an R(ACK) block with a block number equal to

the current block number is received, the Reader shall toggle the

current block number before optionally sending a block to the

SRTAG2KL.

SRTAG2KL rules:

Rule C. The SRTAG2KL block number shall be initialized to 1 at activation.

Rule D.

When an I-block is received, the SRTAG2KL shall toggle its block

number before sending a block.

Note:

The SRTAG2KL may check if the received block number is not in compliance

with Reader rules to decide neither to toggle its internal block number nor to

send a response block.

Rule E.

When an R(ACK) block with a block number not equal to the current

SRTAG2KL block number is received, the SRTAG2KL shall toggle its

block number before sending a block.

Note:

There is no block number toggling when an R(NAK) block is received.
