Reserved. Set = 0.
These bits are for programming the PLL
’
s internal N register. This access allows the user to
modify the CPU frequency at very high resolution (accuracy). All other synchronous clocks
(clocks that are generated from the same PLL, such as PCI) remain at their existing ratios
relative to the CPU clock.

R and N register mux selection. 0 = R and N values come from the ROM. 1 = data is loaded
from DAF (SMBus) registers.
Note:
