ODT loading differs from that used in AC timing measurements. The reference load for
ODT timings is shown in Figure 25. Two parameters define when ODT turns on or off
synchronously, two define when ODT turns on or off asynchronously, and another
defines when ODT turns on or off dynamically. Table 33 outlines and provides definition
and measurement reference settings for each parameter (see Figure 34 on page 52).
ODT turn-on time begins when the output leaves High-Z and ODT resistance begins to
turn on. ODT turn-off time begins when the output leaves Low-Z and ODT resistance
begins to turn off.
