Table 139. Description of RFTReg bits
The PN512 supports direct interfacing of hosts using SPI, I
interfaces. The PN512 resets its interface and checks the current host interface type
automatically after performing a power-on or hard reset. The PN512 identifies the host
interface by sensing the logic levels on the control pins after the reset phase. This is done
using a combination of fixed pin connections.
