Write Timing (using R/W, CS0-controlled)
Figure 37 shows the write-timing behavior when the WR(R/W) input is programmed as a combined read-write input R/W.
The RD input has to be tied to high-level in this configuration. This timing is called CS0-controlled because CS0 is the last
external signal of CS0, CS1, and R/W, which becomes valid.
