11.3 MIFARE Write

The MIFARE Write requires a block address, and writes 16 Bytes of data into the

addressed MIFARE Classic 1K block. It needs two pairs of command-response. These

two parts, MIFARE Write part 1 and part 2 are shown in Figure 15, Figure 16 and

Table 16.

Table 17 shows the required timing.
