Power down clock input section
Powers down the clock input section (including CLK buffer, VCO divider, and CLK tree).
0: normal operation (default).
1: power-down.
3
Power down VCO clock interface
Powers down the interface block between VCO and clock distribution.
0: normal operation (default).
1: power-down.
2
Power down VCO and CLK
Powers down both VCO and CLK input.
0; normal operation (default).
1: power-down.
0x1E1
1
Select VCO or CLK
Selects either the VCO or the CLK as the input to VCO divider.
0: selects external CLK as input to VCO divider (default).
1: selects VCO as input to VCO divider; cannot bypass VCO divider when this is selected.
0
Bypass VCO divider
Bypasses or uses the VCO divider.
0: uses VCO divider (default).
1: bypasses VCO divider; cannot select VCO as input when this is selected.

Power down SYNC
Powers down the SYNC function.
0: normal operation of the SYNC function (default).
1: powers down SYNC circuitry.
1
Power down distribution reference
Powers down the reference for distribution section.
0: normal operation of the reference for the distribution section (default).
1: powers down the reference for the distribution section.
0
Soft SYNC
The soft SYNC bit works the same as the SYNC pin, except that the polarity of the bit
is reversed. That is, a high level forces selected channels into a predetermined static
state, and a 1-to-0 transition triggers a SYNC.
0: same as SYNC high (default).
1: same as SYNC low.

Update all registers
This bit must be set to 1 to transfer the contents of the buffer registers into the active
registers. This bit is self-clearing; that is, it does not have to be set back to 0.
1 (self-clearing): updates all active registers to the contents of the buffer registers.
