Write Timing (using WR, WR-controlled)
Figure 39 shows the write-timing behavior when the WR(R/W) input is programmed as a write input WR only. The input
RD acts as the read input in this configuration. This timing is called WR-controlled because WR is the last external signal
of CS0, CS1, and WR, which becomes valid.
