Bit 7:4 – RF_MC
These register bits provide the matching control of the differential RF pins (RFN, RFP)
by switching capacitances to ground, see Figure 2-2.
Each step increases the
capacitance by 36 fF at each pin. The capacitance setting at the RF pins is valid for
both RX and TX operation.

Bit 7 – RX_PDT_DIS
RX_PDT_DIS = 1 prevents the reception of a frame, even if the radio transceiver is in
receive mode. An ongoing frame reception is not affected.
