Appeal No. 1998-0069
Application 08/356,946
to eliminate pull-up and pull-down resistors, but to
provide, during an operational mode, fixed logic level
signals at the outputs of one device that are connected by
way of circuit traces to inputs of other devices so that
boundary scan testing of the electric connections between
devices can be made (RBr4).
We agree with Appellants reasoning. Generation of an
internal logic level value does not help to test the
interconnection between devices having BSCs.
For the reasons stated above, we conclude that the
Examiner has failed to establish a prima facie case of
obviousness. The rejection of claims 1-17 is reversed.
