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:
5.
When writing to this register, the device will acknowledge the Write operation, but the data itself will be ignored.
