2.  WCK and CK are shown aligned (tWCK2CKPIN=0, tWCK2CK=0) for illustration purposes.  WCK2CK training determines the needed offset between WCK and CK.
4.  tCCD = tCCDL when bank groups are enabled and both READs access banks in the same bank group; otherwise tCCD=tCCDS. 
5.  Before the READ commands, an ACTIVE (ACT) command is required to be issued to the GDDR5 SGRAM and tRCDRD must be met.
1.  CLmrs = 6 is shown as an example.  Actual supported values will be found in the MR and AC timings sections.
3.  EDC may be on or off.  See Figure 4 for EDC Timing.
Notes:
6.  tWCK2DQI = 0 is shown for illustration purposes.
