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

–

Logic level low

Q –

Output data

T –

Time

V –

Valid

X –

No longer a valid logic level

Z –

Float
