11.3 RF level detector
The following abbreviations are used:
Remark: If only 1 driver is switched on, the values for ModGsOn and CWGsOn 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.
The sensitivity of the RF level detector is adjustable in a 4-bit range using the bits RFLevel
in register RFCfgReg. The sensitivity itself depends on the antenna configuration and
tuning.
Possible sensitivity levels at the RX pin are listed in the
Table 152. Setting of the bits RFlevel in register RFCfgReg (RFLevel amplifier deactivated)
