VPR1 and VPR0 — VCO Power-of-Two Range Select Bits
4.5.2 PLL Bandwidth Control Register
The PLL bandwidth control register (PBWC):
AUTO — Automatic Bandwidth Control Bit
Freescale Semiconductor
These read/write bits control the VCO’s hardware power-of-two range multiplier E that, in conjunction
with L controls the hardware center-of-range frequency, f
PLLON bit is set. Reset clears these bits. (See
4.5.5 PLL VCO Range Select

•
This read/write bit selects automatic or manual bandwidth control. When initializing the PLL for manual
operation (AUTO = 0), clear the ACQ bit before turning on the PLL. Reset clears the AUTO bit.
1 = Automatic bandwidth control
0 = Manual bandwidth control
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
Address:
Verify that the value of the VPR1 and VPR0 bits in the PCTL register are
appropriate for the given reference and VCO clock frequencies before
enabling the PLL. See
on selecting the proper value for these control bits.
