VPR1 and VPR0 — VCO Power-of-Two Range Select Bits
These read/write bits control the VCO’s hardware power-of-two range multiplier
E that, in conjunction with L (See 4.3.3 PLL Circuits, 4.3.6 Programming the
center-of-range frequency, fVRS. VPR1:VPR0 cannot be written when the
PLLON bit is set. Reset clears these bits.
4.5.2 PLL Bandwidth Control Register
The PLL bandwidth control register (PBWC):
Selects automatic or manual (software-controlled) bandwidth control mode
Indicates when the PLL is locked
In automatic bandwidth control mode, indicates when the PLL is in
acquisition or tracking mode
In manual operation, forces the PLL into acquisition or tracking mode
