Name
Start High Divider 4.1
Divider 4 DCCOFF
Description
This bit must be set to 1 to transfer the contents of the buffer registers into the active registers. This happens
on the next SCLK rising edge. This bit is self-clearing; that is, it does not have to be set back to 0.
[0] = 1 (self-clearing); update all active registers to the contents of the buffer registers.
Description
Divider 4.1 start high/low.
[0] = 0; start low (default).
[0] = 1; start high.
Duty-cycle correction function.
[0] = 0; enable duty-cycle correction (default).
[0] = 1; disable duty-cycle correction.

[0] = 1; bypass VCO divider.
Description
Power down the SYNC function.
[2] = 0; normal operation of the SYNC function (default).
[2] = 1; power-down SYNC circuitry.
Power down the reference for distribution section.
[1] = 0; normal operation of the reference for the distribution section (default).
[1] = 1; power down the reference for the distribution section.
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] = 0; same as SYNC high (default).
[0] = 1; same as SYNC low.
