Notes:
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

(Load Capacitance for port 0, ALE and PSEN = 60 pF; Load Capacitance for all other
outputs = 60 pF.)
Table 123, Table 126 and Table 129 give the description of each AC symbols.
Table 124, Table 128 and Table 130 give for each range the AC parameter.
Table 125, Table 128 and Table 131 give the frequency derating formula of the AC
parameter for each speed range description. To calculate each AC symbols: Take the x
value and use this value in the formula.
