10.4 MIFARE Increment, Decrement and Restore
Table 17.
These times exclude the end of communication of the PCD.
Remark: The minimum required time between MIFARE Write part 1 and part 2 is the
minimum required FDT acc. to
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
