5.1.1 Initiator

Once the Initial RF Collision is completed and no RF field has been detected (as shown in Figure 11), the following registers must be modified to initialize the anticollision (as shown in Figure 12). For more information, see Section 2.

1. Delay time specified in the technology specification (56 µs to 188 µs).
2. ISO Control register (0x01) → 0x32 (NFC-F at 212 kbps, receive with CRC).
3. Delay 1 ms
4. Send packet:
   1. Reset FIFO (0x0F) direct command.
   2. Transmission with CRC direct command (0x11).
   3. TX Length Byte 1 and 2 (0x1D and 0x1E) registers.
   4. Write the response to the FIFO.
