11.6.2 Waveform shape for ISO/IEC 14443A and MIFARE S
The secure IC, e.g. the SmartMX is connected to the PN512 via the pins SIGOUT and
SIGIN.
The waveform shape at SIGOUT is a digital 13.56 MHz Miller coded signal with levels
between PVSS and PVDD derived out of the external 13.56 MHz carrier signal in case of
the Contactless Card mode or internally generated in terms of Secure Access mode.
The register TxSelReg controls the setting at SIGOUT.
Note: The clock settings for the Secure Access mode and the Contactless Card mode
differ, refer to the description of the bits SAMClockSel in register TestSel1Reg.
The signal at SIGIN is a digital Manchester coded signal according to the requirements of
the ISO/IEC 14443A with the subcarrier frequency of 847.5 kHz generated by the secure
IC.
