12.3 MIFARE Write
The MIFARE Write requires a block address, and writes 16 bytes of data into the
addressed MIFARE Classic EV1 with 1K memory block. It needs two pairs of command-
response. These two parts, MIFARE Write part 1 and part 2 are shown in Figure 18 and
Figure 19 and Table 24.
Table 25 shows the required timing.

12.4 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 the Transfer Buffer.
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 the Transfer
Buffer.
The MIFARE Restore requires a source block address. It copies the value of the
addressed block into the Transfer Buffer. The 4 byte Operand in the second part of the
command is not used and may contain arbitrary values.
All three commands are responding with a NAK to the first command part if the
addressed block is not formatted to be a valid value block, see Section 8.6.2.1.
The two parts of each command are shown in Figure 20 and Figure 21 and Table 26.
Table 27 shows the required timing.

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.
