ISO/IEC 14443 A Reader IC
internal analog signals for measurement on pin AUX
internal digital signals for observation on pin MFOUT (based on register selections)
These measurements can be helpful during the design-in phase to optimize the receiver’s
behavior, or for test purposes.
15.2.1
Measurements using the serial signal switch
Using the serial signal switch on pin MFOUT, data is observed that is sent to the card or
received from the card.
Table 167
gives an overview of the different signals available.

TX control
Figure 25
shows as an example of an ISO/IEC 14443 A communication.
The signal is measured on pin MFOUT using the serial signal switch to control the data
sent to the card. Setting the flag MFOUTSelect[2:0] = 3 sends the data to the card coded
as NRZ. Setting MFOUTSelect[2:0] = 2 shows the data as a Miller coded signal.
The RFOut signal is measured directly on the antenna and gives the RF signal pulse
shape. Refer to Application note
Directly matched Antenna - Excel calculation
(
Ref. 3
) for
detail information on the RF signal pulse.
