General PLL Unlocked parts

General PLL Unlocked parts. The PLL chain consists of: a) Reference frequency & reference (R) divider. MUXOUT can be programmed to check for the presence of stable pulses on the R. If these are present, then the reference oscillator & programming are OK. b) VCO & feedback (N) divider.
