Note:
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 sig-
nal or the logical status of that signal. The following is a list of all the characters and
what they stand for.

Table 3. gives the maximum applicable load capacitance for Port 1, 3 and 4. Timings will
be guaranteed if these capacitances are respected. Higher capacitance values can be
used, but timings will then be degraded.
