The following abbreviations have been used in Table 15 and Table 16:
• 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
• nMod: NMOS conductance value for modulation defined by the GsNReg register’s
ModGsN[3:0] bits
• X = do not care.
Remark: If only one driver is switched on, the values for CWGsPReg, ModGsPReg and
GsNReg registers are used for both drivers.
