DI a-b = data in for bank a, column b.
3 subsequent elements of data in are applied in the programmed order following DI a-b.
A non-interrupted burst is shown.
A10 is Low with the Write command (Auto Precharge is disabled).
QFC is an open drain driver. Its output high level is achieved through an externally connected pull up resistor connected to V
