CR5 Register (Power On State = “00000”)
D0 : ( PL1/8) :
Select the divider by 8 for PLL1,
PL1/8 = “1” CLK1 output frequency is divided by 8.
PL1/8 = “0” CLK1 output frequency is as per table 4.
D1 : ( PL2/8) :
Select the divider by 8 for PLL2,
PL2/8 = “1” CLK2 output frequency is divided by 8.
PL2/8 = “0” CLK2 output frequency is as per table 5.
D2 : ( CLK2EN) , PLL2:
Output enable bit,
CLK2EN = “1” CLK2 output is enabled.
