3-8. Fast Write Multiple Blocks Command
Description of command
The Fast Write Multiple Blocks command is the same as the Write Multiple Blocks command that writes the
successive multiple-block data included in the request. The datarate in the response is twice as defined in ISO/
IEC 15693.
Up to 2 blocks of data can be written for one request.
The transponder performs verification after writing and returns an error code if the writing has failed. Up to 2
blocks of data can be written for one request. The number of blocks specified in the Fast Write Multiple Blocks
command is similar to the number of blocks specified in the Read Multiple Blocks command. The value of the
number of blocks field specified in the Fast Write Multiple Blocks command is obtained by subtracting 1 from
the number of the expected blocks to be written.
Setting the number of blocks to “01
H
” makes a request to write 2 blocks. Setting the number of blocks to “00
H
”
makes a request to write 1 block (the request having the same effect as the Fast Write Single Block command).
If at least one of the blocks specified for data writing is locked, the transponder does not write any data and,
instead, returns an error code.
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 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 returns its response. (However, if an EOF is not sent within 38 ms, the time-out occurs and
the transponder can receive another command.)
