LOW-to-HIGH Transition
Note 1:
The data output functions may be enabled or disabled by various signals at the GAB and GBA inputs. Data input functions are always enabled,
i.e., data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs.
Note 2:
If the select control is LOW, the clocks can occur simultaneously. If the select control is HIGH, the clocks must be staggered in order to load both
registers.
