SDRAM Mode Register Accesses.
SDRAM Mode Register Accesses are handled
by the SDRAM/NORMAL clocking options. This access is marked mainly by
L_RAS~ and L_CAS~ signals both going low together which does not happen
for normal or burst in Read or Write Cycle types. When L_RAS~ AND L_CAS~
are both low at a rising CKIO edge, the Address, Data, and Control signals are
logged-in and mastered see Figure 2–7.
