ABSTRACT:
A logic output macrocell (30) is programmable to select between a registered output (38a-n) or a nonregistered output (42a-n). The selection between the two outputs can be either reversible through coupling to a selecting output (58) of a combinatorial logic matrix (12) or it can be permanently programmed with the aid of an architectural fuse (52a-n).
