cycle when the DCM completes one phase adjustment. After PSDONE is deasserted, PSEN
can be asserted again, allowing an additional phase shift to occur.

guaranteed. Also, the PSINCDEC value at T
determines whether it is an increment (logic High) or a decrement (logic Low).

the phase shift is complete. The time required for a complete phase shift varies. As a
result, PSDONE must be monitored for phase-shift status.
