6.12.2 Initiator
The chip is fully controlled by the MCU as in RFID reader operation. The MCU activates the chip and
writes the mode selection in the ISO Control register. The MCU uses RF collision avoidance commands,
so it is relieved of any real-time task. The normal transmit and receive procedure (through the FIFO) are
used to communicate with the TARGET device as described in
