High voltage level
High voltage level one set-up time prior to the High-to-Low
clock transition
Low voltage level
Low voltage level one set-up time prior to the High-to-Low
clock transition
Lower case letters indicate the state of the referenced input
(or output) one set-up time prior to the High-to-Low clock
transition
