1.2 Terminology
In this document a “#” symbol following a signal name indicates that the signal is active low. This
means that when the signal is asserted (based on the name of the signal) it is in an electrical low
state. Otherwise, signals are driven in an electrical high state when they are asserted. In state
machine diagrams, a signal name in a condition indicates the condition of that signal being
asserted. If the signal name is preceded by a “!” symbol, then it indicates the condition of that
signal not being asserted. For example, the condition “!STPCLK# and HS” is equivalent to “the
active low signal STPCLK# is unasserted (i.e., it is at 1.5V) and the HS condition is true.” The
symbols “L” and “H” refer respectively to electrical low and electrical high signal levels. The
