Description
Connect OUT0 and OUT1 to Divider 0 or directly to VCO or CLK.
<1> = 0: OUT0 and OUT1 are connected to Divider 0.
<1> = 1:
If 0x1E1<1:0> = 10b, the VCO is routed directly to OUT0 and OUT1.
If 0x1E1<1:0> = 00b, the CLK is routed directly to OUT0 and OUT1.
If 0x1E1<1:0> = 01b, there is no effect.
Duty-cycle correction function.
<0> = 0; enable duty-cycle correction.
<0> = 1; disable duty-cycle correction.
Number of clock cycles of the divider input during which divider output stays low.
Number of clock cycles of the divider input during which divider output stays high.
Bypass and power down the divider; route input to divider output.
<7> = 0; use divider.
<7> = 1; bypass divider.
Nosync.
<6> = 0; obey chip-level SYNC signal.
<6> = 1; ignore chip-level SYNC signal.
Force divider output to high. This requires that nosync also be set.
<5> = 0; divider output forced to low.
<5> = 1; divider output forced to high.
Selects clock output to start high or start low.
<4> = 0; start low.
<4> = 1; start high.
Phase offset.
Connect OUT2 and OUT3 to Divider 1 or directly to VCO or CLK.
<1> = 0; OUT2 and OUT3 are connected to Divider 1.
<1> = 1:
If 0x1E1<1:0> = 10b, the VCO is routed directly to OUT2 and OUT3.
If 0x1E1<1:0> = 00b, the CLK is routed directly to OUT2 and OUT3.
If 0x1E1<1:0> = 01b, there is no effect.
Duty-cycle correction function.
<0> = 0; enable duty-cycle correction.
<0> = 1; disable duty-cycle correction.
Number of clock cycles of the divider input during which divider output stays low.
Number of clock cycles of the divider input during which divider output stays high.

<7> = 0; use divider.
<7> = 1; bypass divider.

<6> = 0; obey chip-level SYNC signal.
<6> = 1; ignore chip-level SYNC signal.
Force divider output to high. This requires that nosync also be set.
<5> = 0; divider output forced to low.
<5> = 1; divider output forced to high.
Selects clock output to start high or start low.
<4> = 0; start low.
