Digital XTAL load cap programming.
LD pin output selection. Set D13:D10 = 0000: PLL lock-detect signal.
Charge-pump current selection. Set 1 for 1mA and 0 for 0.5mA.
Set 0 for normal operation or 1 to disable the PLL phase frequency detector.
Reserved.
Charge-pump test. Set D6:D4 = 000: normal operation; X10: pump up; X01 = pump
down; 100 = high impedance; 111: both up and down on.
PLL mode control. Set 1 to enable the integer-N PLL or 0 to enable the fractional-N PLL.
PLL power-save mode. Set 1 to enable the power-save mode or 0 to disable.
