Hi

     I am an engineer of NFC reader developed. My question is :

What does the mean of N - driver or P-driver ? The value of register(GsNOnReg 、CWGsPReg and ModGsPreg) how to influence antenna modulation ?

 

Is there any other way to know  a card in antenna field without by searching card command, for example ,read some value of register.

 

Best regard!
