Remark:
The minimum required time between MIFARE Increment, Decrement, and
Restore part 1 and part 2 is the minimum required FDT acc. to
Ref. 4
. There is no
maximum specified.
Remark:
The MIFARE Increment, Decrement, and Restore require a MIFARE Transfer to
store the value into a destination block.
Remark:
The MIFARE Increment, Decrement, and Restore command part 2 does not
provide an acknowledgement, so the regular time out has to be used instead.
11.5 MIFARE Transfer
The MIFARE Transfer requires a destination block address, and writes the value stored in
the volatile memory into one MIFARE Classic block. The command structure is shown in
Figure 19
and
Table 20
.
Table 21
shows the required timing.
