Abstract
Efficient register circuits allow the loading of data values into a memory element using set and reset terminals in addition to loading via the data input terminal. A register circuit includes a memory element and a logical AND gate. A load command input terminal enables the load, and a load value input terminal provides the new value to be loaded. The memory element has set and reset terminals. In one embodiment, the reset function overrides the set function when both terminals provide active signals. The set terminal is coupled to the load command input terminal. The logical AND gate has input terminals coupled to the load command and load value input terminals, and an output terminal coupled to the reset terminal of the memory element. In another embodiment, the set function overrides the reset function, and the signals driving the set and reset terminals are reversed.
