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 sig-
nal. The following is a list of all the characters and what they stand for.
For example:
TAVLL = Time from Address Valid to ALE Low
TLLPL = Time from ALE Low to PSEN# Low
A: Address
Q: Output data
C: Clock
R: RD# signal
D: Input data
T: Time
H: Logic level HIGH
V: Valid
I:
Instruction (program memory contents)
W: WR# signal
L: Logic level LOW or ALE
X: No longer a valid logic level
P: PSEN#
Z: High Impedance (Float)
