Input/output characterization register (chain) for an integrated circuit

摘要

An input/output characterization register (10) is provided for characterizing an integrated circuit input or output. The register includes a normal data input (18), a characterization data input (20), and a data latch (30) having a latch control input (40), a latch data input (41) and a latch data output (42). The normal data input and the characterization data input are multiplexed with the latch data output to the latch data input. <IMAGE>
