LPFD:
Internal FET drain output pin for PLL
This pin is combined with CPFM/CPAM pins
to form a low pass filter for PLL.
CPFM, CPAM:
Charge pump output pins
These pins are placed in high-impedance
state in BACKUP mode, at power-on-reset
time, and in PLL stop state.

Both are of open drain type.
External pull-up resistors are needed.
Use the same power supply for the pull-up
resistors and Pin 34 BUS.
These pins are set to an input port at
RESET time.
