15.2.1.2 RX control

Figure 29 shows an example of ISO/IEC 14443 A communication which represents the

beginning of a card’s answer to a request signal.

The RF signal shows the RF voltage measured directly on the antenna so that the card’s

load modulation is visible. Setting MFOUTSelect[2:0] = 4 shows the Manchester decoded

signal with subcarrier. Setting MFOUTSelect[2:0] = 5 shows the Manchester decoded

signal.
