5 PLL_P1[8] This sets the MSB of the 1st P Divider on the PLL which is part of a standard half-cycle divider
control.
6 PLL_P2[8] This sets the MSB of the 2nd P Divider on PLL which is part of a standard half-cycle divider
control.
TABLE 37. PLL_P1 (0x07h)
Bits Field Description
7:0 PLL_P1[7:0] This programs the 8 LSBs of the PLL's P1 Divider. These LSBs combine with PL1_P1[8] which
allows the P1 divider to divide by up to 256.

TABLE 38. PLL_P2 (0x08h)
Bits Field Description
7:0 PLL_P2[7:0] This programs 8 LSBs of the PLL's P2 Divider. These LSBs combine with PLL_P2[8] which
allows the P2 divider to divide by up to 256.
