Table 5–17. Phase Counter Select Mapping
To perform one dynamic phase-shift, follow these steps:
1. Set PHASEUPDOWN and PHASECOUNTERSELECT as required.
2. Assert PHASESTEP. Each PHASESTEP pulse enables one phase shift. The PHASESTEP
3. Wait for PHASEDONE to go low.
4. De-assert PHASESTEP.
5. Wait for PHASEDONE to go high.
6. Repeat steps 1-5 as many times as required to perform multiple phase-shifts.
All signals are synchronous to SCANCLK and are latched on the SCANCLK edges and
must meet tsu/th requirements with respect to SCANCLK edges.
Free running clock from the core used
in combination with PHASESTEP to
enable and disable dynamic phase
shifting. Shared with SCANCLK for
dynamic reconfiguration.
When asserted, this indicates to
core-logic that the phase adjustment is
complete and the PLL is ready to act
on a possible second adjustment
pulse. Asserts based on internal PLL
timing. De-asserts on the rising edge
of SCANCLK.
pulses must be at least one scanclk cycle apart.
