2-9. Lock AFI command
Description of command
On receiving the Lock AFI command, the transponder locks (write disable) the stored AFI.
The transponder performs verification after writing and returns an error code if the writing has failed.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the lock operation
starting after <t1nom
+
a multiple of 4096/fc (302.1
μ
s)> with total tolerance of -32/fc to +32/fc (2.4
μ
s) and latest
within 20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and the
transponder can receive another command.)
Once the Lock AFI command has been received, the AFI cannot be changed by the Write AFI command.

2-10. Write DSFID command
Description of command
On receiving the Write DSFID command, the transponder writes the specified DSFID to FRAM.
The transponder performs verification after writing and returns an error code if the writing has failed.
If the Option_flag (bit 7) is “0”, the transponder shall return its response when it has completed the write operation
starting after <t1nom
+
a multiple of 4096/fc (302.1
μ
s)> with total tolerance of
±
32/fc (2.4
μ
s) and latest within
20 ms. If it is “1”, transponder shall wait for the reception of an EOF from the reader/writer and upon such
reception still return its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and the
transponder can receive another command.)
