Clock Generator Module (CGM)
5.5.3 PLL Multiplier Select Registers
The PLL multiplier select registers (PMSH and PMSL) contain the programming information for the
modulo feedback divider.
MUL[11:0] — Multiplier Select Bits
5.5.4 PLL VCO Range Select Register
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

These read/write bits control the modulo feedback divider that selects the VCO frequency multiplier N.
(See
registers configure the modulo feedback divider the same as a value of $0001. Reset initializes the
registers to $0040 for a default multiply value of 64.
These read/write bits control the hardware center-of-range linear multiplier L which, in conjunction with
