** NOP is only inserted for CAS3
**** The number of NOPs is equal to WRDLY[1:0] + 1 (WRDLY = 0 is shown)
***** The number of NOPs is equal to RPDLY[1:0] (RPDLY = 1 is shown)
* The number of NOPs is equal to ROWCOLDLY[2:0] (ROWCOLDLY = 1 is shown)
*** Clock suspended for 1 cycle when EBI is running at 1x and 1 or 2 cycles when EBI
is running at 2x, to enable sampling of data on the positive edge of the 1x clock.
