Abstract
A process includes coupling a push-pull driver of a first bus device to a plurality of communication lines that are associated with a first bus to allow the first bus device to access the first bus using push-pull signaling. The process includes sharing a set of communication lines with the second bus. The sharing includes coupling an open drain driver of a second bus device to the set of communication lines to allow the second bus device to access the second bus using open drain signaling. The sharing includes using the set of communication lines in first time periods in which the first bus device accesses the first bus and using the set of communication lines in second time periods other than the first time periods in which the second bus device accesses the second bus. The sharing includes isolating a push-pull driver of the first bus device from the set of communication lines responsive to the second time periods.
