The data output functions can be enabled or disabled by a variety of level combinations at OEAB or OEBA. Data input functions always are
enabled; i.e., data at the bus terminals is stored on every low-to-high transition on the clock inputs.
Select control = L: clocks can occur simultaneously.
Select control = H: clocks must be staggered to load both registers.
