timing and signal description of the THS12082 (continued)
write timing (using R/W, CS0-controlled)
Figure 12 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 that becomes valid.
