Start High Divider 4.1
Divider 4 DCCOFF
Description
Bypass (and power down) 4.2 divider logic, route clock to 4.2 output.
<5> = 0; do not bypass.
<5> = 1; bypass.
Bypass (and power down) 4.1 divider logic, route clock to 4.1 output.
<4> = 0; do not bypass.
<4> = 1; bypass.
Nosync.
<3> = 0; obey chip-level SYNC signal.
<3> = 1; ignore chip-level SYNC signal.
Force Divider 4 output high. Requires that nosync also be set.
<2> = 0; force low.
<2> = 1; force high.
Divider 4.2 start high/low.
<1> = 0; start low.
<1> = 1; start high.
Divider 4.1 start high/low.
<0> = 0; start low.
<0> = 1; start high.
Duty-cycle correction function.
<0> = 0; enable duty-cycle correction.
<0> = 1; disable duty-cycle correction.

<4> = 0; normal operation.
<4> = 1; power-down.
<3> = 0; normal operation.
<3> = 1; power-down.
Power down both VCO and CLK input.
<2> = 0; normal operation.
<2> = 1; power-down.
Select either the VCO or the CLK as the input to VCO divider.
<1> = 0; select external CLK as input to VCO divider.
<1> = 1; select VCO as input to VCO divider; cannot bypass VCO divider when this is selected.
Bypass or use the VCO divider.
<0> = 0; use VCO divider.
<0> = 1; bypass VCO divider; cannot select VCO as input when this is selected.
