14.15 PERSPECTIVE ON STATE CODE ASSIGNMENTS OF
FUNDAMENTAL MODE FSMs
Before the subject of state code assignments can be properly considered, it is necessary to
clear up any confusion the reader may have regarding the types of asynchronous FSMs that
have been considered. All asynchronous FSMs considered to this point have been those
