13.9.1 Bandwidth Control Register
13.9.2 VCO Control Register (PVCR)
Technical Data

The bandwidth control register (PBWC) contains control/status bits for
both PLLs.
LOCKx — Lock Indicator Bit
PLLONx — PLL On Bit
The VCO control register configures the VCO for both PLLs.
VCO_[7:0] — VCO Control Bits for both PLLs
Read:

Write:
This read-only bit becomes set when the VCO clock is locked (running
at the programmed frequency).
This read/write bit activates each PLL and enables the VCO clock.
Set VCO_[7:0] = $80 for maximum performance.
1 = VCO frequency correct or locked
0 = VCO frequency incorrect or unlocked
1 = PLL on
0 = PLL off
