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.

Table 24. gives the maximum applicable load capacitance for Port 0, Port 1, 2 and 3,
and ALE and PSEN signals. Timings will be guaranteed if these capacitances are
respected. Higher capacitance values can be used, but timings will then be degraded.
Table 24. Load Capacitance versus speed range, in pF
Table 5., Table 29. and Table 32. give the description of each AC symbols.
Table 27., Table 30. and Table 33. give for each range the AC parameter.
