Abstract
A bus master controller comprising a plurality of logic modules, each module coupled to a separate bus driver circuit. The logic module operates using a 'break-before-make' protocol derived from a finite state machine, delay element and exclusive-OR gate. The finite state machine generates a predetermined sequence that requires an 'assert' signal to always be delayed with respect to a 'de-assert' signal, thus eliminating the possibility that more than one set of bus drivers will be coupled to the bus at any one time.
