4.8.10 DDRIOLogicDelayA[0:1]—DDRIOLogicDelay Register
Logic delay control register. When set, the corresponding PI group is delayed by one
qclk.
The LogicDelay register settings are additive delays to either the PhaseDelay setting or
the CMD/CTL PI settings, depending on the CmdXoverEnable setting.
