    The polarity of the data must be checked with a POLARITY signal. The polarity is positive when the POLARITY signal is OFF and negative when the POLARITY signal is ON. The K3NX in output test has test data output regardless of the type of REQ sig- nal. Operating Conditions The RUN signal is turned ON in RUN or output test.
