Remark: If only one driver is switched on, the values for CWGsPReg, ModGsPReg and
GsNReg registers are used for both drivers.
The RF level detector is integrated to fulfill NFCIP1 protocol requirements (e.g. RF
collision avoidance). Furthermore the RF level detector can be used to wake up the
PN512 and to generate an interrupt.

RF: 13.56 MHz clock derived from 27.12 MHz quartz crystal oscillator divided by 2
RF_n: inverted 13.56 MHz clock
GSPMos: conductance, configuration of the PMOS array
GSNMos: conductance, configuration of the NMOS array
pCW: PMOS conductance value for continuous wave defined by the CWGsPReg
register
pMod: PMOS conductance value for modulation defined by the ModGsPReg register
nCW: NMOS conductance value for continuous wave defined by the GsNReg
register’s CWGsN[3:0] bits
