Table 5–10. Phase Counter Select Mapping
To perform one dynamic phase shift step, you must perform the following
procedures:
1. Set phaseupdown and phasecounterselect as required.
2. Assert phasestep for at least two scanclk cycles. Each phasestep pulse
3. Deassert phasestep.
4. Wait for phasedone to go high.
5. You can repeat steps
All signals are synchronous to scanclk, so they are latched on the scanclk edges
and must meet t
