Remark: The minimum required time between MIFARE Write part 1 and part 2 is the

minimum required FDT acc. to Ref. 4. There is no maximum specified.

11.4 MIFARE Increment, Decrement and Restore

The MIFARE Increment requires a source block address and an operand. It adds the

operand to the value of the addressed block, and stores the result in a volatile memory.

The MIFARE Decrement requires a source block address and an operand. It subtracts the

operand from the value of the addressed block, and stores the result in a volatile memory.

The MIFARE Restore requires a source block address. It copies the value of the

addressed block into a volatile memory.

These two parts of each command are shown in Figure 17, Figure 18 and Table 18.

Table 19 shows the required timing.
