Abstract:
A programmable interface comprising:first means for selecting one or more components from a plurality of components in response to at least one first control signal; second means for selectively connecting said components in response to at least one second control signal; wherein said interface includes a plurality of stages, at least one of said stages is associated with each of said components; wherein said first means includes means disposed within each stage for selecting an associated component and wherein said means disposed within each stage for selecting an associated component is a flow-through latch; wherein said second means includes means disposed within each stage for selectively connecting an associated component to a second component and wherein said means disposed within each stage for selectively connecting an associated component to a second component is a first multiplexer; and wherein said third means includes means disposed within each stage for connecting the test data input of the associated component to the test data output of another selected component or the test data output of a bus controller, wherein said means disposed within each stage for connecting the test data input of the associated component to the test data output of another selected component of the test data output of a bus controller is a second multiplexer; and third means for selecting a serial output mode or a parallel output mode of said components in response to at least one third control signal.
