Description
Number of clock cycles (minus 1) of the divider input during which the 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 the 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).
Channel 0 powers down.
[2] = 0; normal operation (default).
[2] = 1; powered down. (OUT0/OUT0, OUT1/OUT1, and OUT2/OUT2 are put into the high
impedance power-down mode by setting this bit.)
Duty-cycle correction function.
[0] = 0; enable duty-cycle correction (default).
[0] = 1; disable duty-cycle correction.
Number of clock cycles (minus 1) of the divider input during which the divider output stays
low. A value of 0x3 means the divider is low for four input clock cycles (default: 0x3).
Number of clock cycles (minus 1) of the divider input during which the divider output stays
high. A value of 0x3 means the divider is high for four input clock cycles (default: 0x3).
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.
