This chapter discusses general document information about the Tsi148 PCI/X-to-VME Bus
Bridge User Manual. The following topics are described:

This section explains the document conventions used in this manual.
Non-differential signals, such as those used by the PCI/X standard, are either active high or
active low. Active low signals are defined as true (asserted) when they are at a logic low.
Similarly, active high signals are defined as true at a logic high. Non-differential signals are
considered asserted when active and negated when inactive, irrespective of voltage levels. For
voltage levels, the use of 0 indicates a low voltage while a 1 indicates a high voltage.
Non-differential signals that assume a logic low state when asserted are followed by an
underscore sign as the last non-numerical character, “_”. For example, SIGNAL_[0] is
asserted low to indicate an active low signal. Non-differential signals not followed by an
underscore are asserted when they assume the logic high state. For example, SIGNAL[0] is
asserted high to indicate an active high signal.
