FUNCTION REGISTER (R3)
R3, the function register (C3, C2, C1 set to 0, 1, 1, respectively),
only needs to be programmed during the initialization sequence
(see Table 8).
CPO GND
When the CPO GND bit is low, the charge pump outputs
are internally pulled to ground. This is invoked during the
initialization sequence to discharge the loop filter capacitors.
For normal operation, this bit should be high.

PFD Polarity
This bit should be set to 1 for positive polarity and set to 0 for
negative polarity.
Reserved Bits
The Bit DB15 to Bit DB6 are reserved bits and should be
programmed to hex code 001, and Reserved Bit DB4 should be
set to 1.
