timing and signal description of the THS1206 (continued)
write timing (using WR, WR-controlled)
Figure 16 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.
