AC Parameters
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.
Example:
T
AVLL
= Time for Address Valid to ALE Low.
T
LLPL
= Time for ALE Low to PSEN Low.
T

Load capacitance for Port 0, ALE and PSEN = 100 pF; Load capacitance for all other
outputs = 80 pF.
