8.6.4 PLL VCO Range Select Register
MC68HC908LJ12
Freescale Semiconductor
NOTE:
—
Rev. 2.1
Address:
The PLL VCO range select register (PMRS) contains the programming
information required for the hardware configuration of the VCO.
VRS[7:0] — VCO Range Select Bits
The VCO range select bits have built-in protection such that they cannot
be written when the PLL is on (PLLON = 1) and such that the VCO clock
cannot be selected as the source of the base clock (BCS = 1) if the VCO
range select bits are all clear.
The PLL VCO range select register must be programmed correctly.
Incorrect programming can result in failure of the PLL to achieve lock.

Write:
These read/write bits control the hardware center-of-range linear
multiplier L which, in conjunction with E (See
8.4.6 Programming the

cannot be written when the PLLON bit in the PCTL is set. (See

PLL control register (PCTL). (See
