Notes:
1. tCISKEW represents the total amount of skew consumed by the controller between MDQS[n] and any corresponding bit that
will be captured with MDQS[n]. This should be subtracted from the total timing budget.
2. The amount of skew that can be tolerated from MDQS to a corresponding MDQ signal is called tDISKEW. This can be
determined by the equation: tDISKEW = ± (T/4 – abs (tCISKEW)); where T is the clock period and abs (tCISKEW) is the absolute
value of tCISKEW.
3. This specification applies only to the DDR interface.
