The first of the following tables describes the Pentium II processor signals
that are captured by the preprocessor. The second table lists the label and
symbol encodings defined by the logic analyzer configuration software.
Under the heading "Polarity", negative means that the logic analyzer inverts
N o t e
the signal. Positive means that the logic analyzer does not invert the signal.
