DSM Clock Polarity Select.
0 = No clock inversion.
1 = Clock inversion. Use this setting for normal operation.
Delta Sigma Modulator Bypass.
1 = Disables the delta sigma modulator, resulting in integer division.
0 = Delta sigma modulator along with prescaler defines the divider. Normal operation.
Manual Analog Charge Pump Select.
Selection of analog charge pump level in manual mode when register bit CPSel is set to 1. The levels are defined as
00b = 0.5 mA.
01b = 1.0 mA.
10b = 1.5 mA.
11b = 2.0 mA.
Digital Charge Pump Valve.
00b = 0.5 x analog charge pump level.
01b = 1.0 x analog charge pump level.
10b = 2.0 x analog charge pump level. Use this setting for normal operation.
11b = 3.0 x analog charge pump level.
PLL Lock Detect.
0 = Synthesizer not frequency locked.
1 = Synthesizer is frequency locked.
Manual Override of Automatic Charge Pump Level Select.
0 = Automatic charge pump current selection.
1 = Manual charge pump current selection.
follows:
The digital charge pump is enabled during tuning only.
