Read Timing (using R/W, CS0-controlled)
Figure 34 shows the read-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. The reading of the data
must be done with a certain timing relative to the conversion clock CONV_CLK, as illustrated in Figure 34.
