EXPLANATION OF 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:
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 – Float
Examples:
t
AVLL
- Time for address valid to ALE low.
t
LLPL
- Time for ALE low to PSEN low
