Xtal(1:0)
(0X0D[7:6]) Crystal Oscillator bias current selection
00 = Xtal osc. bias current at 120 μA
01 = Xtal osc. bias current at 180 μA
10 = Xtal osc. bias current at 270 μA
11 = Xtal osc. bias current at 450 μA
If OSCIN is used as a Clock input, the 00 setting should be used to save power.
(0X0D[2:0]) Represents the rate at which the NCO sequence register is reset.
The address 0Dh must be the last register to be written to when effecting a change in PLL.
