9.1 Explanation of symbols
Each timing symbol has 5 characters. The first character is always a ‘T’ (stands for time).
The other characters, depending on their positions, stand for the name of a signal or the
logical status of that signal. The following is a list of all the characters and what they stand
for.
A — Address
C — Clock
D — Input data
H — Logic level HIGH
I — Instruction (program memory contents)
L — Logic level LOW or ALE
P — PSEN
Q — Output data
R — RD signal
T — Time
V — Valid
W — WR signal
X — No longer a valid logic level
Z — High impedance (Float)
