VPR1 and VPR0 — VCO Power-of-Two Range Select Bits
The PLL bandwidth control register (PBWC):
These read/write bits control the VCO’s hardware power-of-two range
multiplier E that, in conjunction with L (See
Programming the
Register.) controls the hardware center-of-range frequency, f
VPR1:VPR0 cannot be written when the PLLON bit is set. Reset
clears these bits.

NOTE: Do not program E to a value of 3.
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
