Remark: The minimum required time between MIFARE Increment, Decrement, and
Restore part 1 and part 2 is the minimum required FDT according to Ref. 4. There is no
maximum time specified.
Remark: The MIFARE Increment, Decrement, and Restore commands 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.
12.5 MIFARE Transfer
The MIFARE Transfer requires a destination block address, and writes the value stored
in the Transfer Buffer into one MIFARE Classic block. The command structure is shown
in Figure 22 and Table 28.
Table 29 shows the required timing.
