OUT11 is enabled only if CSDLD is high. Setting is identical to Register 0x0FC[7].
OUT10 is enabled only if CSDLD is high. Setting is identical to Register 0x0FC[7].
Description
Number of clock cycles (minus 1) of the divider input during which divider output stays low.
A value of 0x7 means the divider is low for eight input clock cycles (default: 0x7).
Number of clock cycles (minus 1) of the divider input during which divider output stays high.
A value of 0x7 means the divider is high for eight input clock cycles (default: 0x7).
Bypasses and powers down the divider; routes input to divider output.
[7] = 0; use divider (default).
[7] = 1; bypass divider.
Ignore SYNC.
[6] = 0; obey chip-level SYNC signal (default).
[6] = 1; ignore chip-level SYNC signal.
Forces divider output to high. This requires that ignore SYNC also be set.
[5] = 0; divider output forced to low (default).
[5] = 1; divider output forced to high.
Selects clock output to start high or start low.
[4] = 0; start low (default).
[4] = 1; start high.
Phase offset (default: 0x0).

Not affected by CSDLD signal (default).
Asynchronous power-down.
Asynchronously enable OUT7 if not powered down by other settings.
To use this feature, the user must use current source digital lock detect
and set the enable LD pin comparator bit (0x01D[3]).
