The PLL uses either 1.6-mA charge pump slices when the PLL is set to fractional mode, or 6.4-mA slices when the PLL is set to integer mode. These slices can be selected by programming R34[3:0]. When the PLL is set to fractional mode, a phase shift must be introduced to maintain a linear response and ensure consistent performance across operating conditions and a value of 0x2 should be programmed in R35[6:4]. When the PLL is set to integer mode, a value of 0x0 should be programmed in R35[6:4].
