Output 11 enabled only if CSDLD is high. Setting is identical to Register 0x0FC[7].
Output 10 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.
No SYNC.
[6] = 0; obey chip-level SYNC signal (default).
[6] = 1; ignore chip-level SYNC signal.
Forces divider output to high. This requires that no 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 Output 7 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]).
