Below is the schematic for 4-bit addition between two 4-bit numbers A[0-3] and B[0-3]. A, B and the results of the addition are connected to a seven-segment hex display to show the results of the addition in Hex.
What do you think would happen if B[0-3] was set to 0, the sum outputs were connected to A[0-3], and carry-in is set to 1? Is this behavior desirable? Is it controllable?
