High-voltage level
High-voltage level one setup time prior to low-to-high
clock transition
Low-voltage level
Low-voltage level one setup time prior to low-to-high
clock transition
Lower case indicate the state of the referenced output
prior to the low-to-high clock transition
Don’t care
Low-to-high clock transition
Not low-to-high clock transition
Both outputs will be high if both SD and RD go low
simultaneously
