Auxiliary Output
: This pin delivers analog test signals. The signal delivered on this
output may be selected by means of the
TestAnaOutSel Register
.

RX
I
Receiver Input
: Input pin for the cards response, which is the load modulated 13.56
MHz energy carrier, that is coupled out from the antenna circuit.
30
VMID
PWR
Internal Reference Voltage
: This pin delivers the internal reference voltage.
Note: It has to be supported by means of a 100 nF block capacitor.
31
RSTPD
I
Reset and Power Down
: When HIGH, internal current sinks are switched off, the
oscillator is inhibited, and the input pads are disconnected from the outside world.
With a negative edge on this pin the internal reset phase starts.
32
OSCOUT
O
Crystal Oscillator Output
: Output of the inverting amplifier of the oscillator.
