NOTES:
1. The data output functions may be enabled or disabled by various signals at the GAB or 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.
2. Select control = L: clocks can occur simultaneously.
Select control = H: clocks must be staggered in order to load both registers.
H = HIGH, L = LOW, X = Don't Care,
≠
= LOW-to-HIGH transition.
