EXPLANATION OF THE AC SYMBOLS
Each timing symbol has five characters. The first character is always
‘t’ (= time). The other characters, depending on their positions,
indicate the name of a signal or the logical status of that signal. The
designations are:
C – Clock
D – Input data
H – Logic level high
L – Logic level low
Q – Output data
T – Time
V – Valid
X – No longer a valid logic level
Z – Float
