7.3.4 System Clock/PLL and Clock Gating Configuration
The system clock/PLL allows the setting of the clocks for the AMD Geode™ system.
Clock Mode: Allows the clock speed to be determined by either the hardware strapping or the manual settings. If the
H/W strapping option is selected, then the manual divisor settings will be grayed out.
Manual divisor settings:
Mdiv: Options from 2 to 17.
Vdiv: Options from 2 to 9.
FbDiv: Options from 6 to 61.
The formula for the MDiv, VDiv, and FbDiv is as follows:
(PCI*FbDiv)/VDiv = CPU speed and (PCI*FbDiv)/MDiv = GeodeLink™ speed.
