This programs the sigma-delta modulator in PLL1
This sets the MSB of the 1st P Divider on PLL1 which is part of a standard half-cycle divider
control.
This sets the MSB of the 2nd P Divider on PLL1 which is part of a standard half-cycle divider
control.
This programs the 8 LSBs of the PLL1's P1 Divider. These LSBs combine with PLL1_P1[8] which
allows the P1 divider to divide by up to 256
This programs 8 LSBs of PLL1's P2 Divider. These LSBs combine with PLL1_P2[8] which allows
the P2 divider to divide by up to 256
