Table 3. Function selection
If nSD and nRD simultaneously go from LOW-to-HIGH, the output states are unpredictable.
H = HIGH voltage level; h = HIGH voltage level one set-up time before the HIGH-to-LOW clock transition;
L = LOW voltage level; l = LOW voltage level one set-up time before the HIGH-to-LOW clock transition;
q = lowercase letters indicate the state of the referenced output one set-up time before the HIGH-to-LOW clock transition;
X = don't care; ↓ = HIGH-to-LOW clock transition.
