Product data
11.1 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
t
AVLL
LLPL
— Time for address valid to ALE LOW
— Time for ALE LOW to PSEN LOW
