A Sequence Counter an N-bit register is a register that is used for counting sequences, starting from 0 to 1 to 2 to 3, and so on, up to 2N-1 -1, then back to 0. Such registers have three inputs; E=1 - enable the circuit to perform its action (E=0 means nothing happens); CLR=1 - clear (ie. reset to 0) the entire register; and, INC=1 - increment the register by 1. The CLR and INC inputs are assumed to be mutually exclusive (ie. both cannot be 1 at the same time, but both can be 0 at the same time). The actions of clearing or incrementing are done only when E=1. Design a complete 4-bit Sequence Counter register and draw its logic diagram.
