This programs the PLL's M divider to divide from 1 to 64.
This programs the PLL N divider to divide from 1 to 250.
This programs the sigma-delta modulator in the PLL.
This sets the MSB of the 1st P Divider on the PLL which is part of a standard half-cycle divider
control.
This sets the MSB of the 2nd P Divider on PLL which is part of a standard half-cycle divider
control.
