(Hex) Bit(s) Name
Description
190
[7:4]
Divider 0 low cycles
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).
190
[3:0]
Divider 0 high cycles
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).
191
[7]
Divider 0 bypass
Bypasses and powers down the divider; routes input to divider output.
[7] = 0; use the divider (default).
[7] = 1; bypass the divider.
191
[6]
Divider 0 ignore SYNC
Ignore SYNC.
[6] = 0; obey chip-level SYNC signal (default).
[6] = 1; ignore chip-level SYNC signal.
191
[5]
Divider 0 force high
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.
191
[4]
Divider 0 start high
Selects clock output to start high or start low.
[4] = 0; start low (default).
[4] = 1; start high.
191
[3:0]
Divider 0 phase offset
Phase offset (default: 0x0).
