The combination of WE & BWS[3:0] defines a write cycle (see Write Cycle Description table).
CE is the combination of CE1, CE2, and CE3. All chip enables need to be active in order to select
the device. Any chip enable can deselect the device. RAx stands for Read Address X, WAx stands for
Write Address X, Dx stands for Data-in for location X, Qx stands for Data-out for location X. CEN held
LOW. During burst writes, byte writes can be conducted by asserting the appropriate BWS[3:0] input signals.
Burst order determined by the state of the MODE input. CEN held LOW. OE held LOW.
