2.3.5 Rx_PD_POL (IF_R[2])
This bit sets the polarity of the Rx phase detector. It is set to one when Rx VCO characteristics are positive. When Rx VCO fre-
quency decreases with increasing control voltage, Rx_PD_POL should set to zero.
2.3.6 Rx_RST (IF_R[1])
This bit will reset the Rx R and N counters when it is set to one. For normal operation, Rx_RST should be set to zero.
