EXPLANATION OF AC SYMBOLS
In an effort to remain compatible with the original 8051 family, this device specifies the same parameters
as such devices, using the same symbols. For completeness, the following is an explanation of the
symbols.

Note 1:
Startup time for crystals varies with load capacitance and manufacturer. Time shown is for an 11.0592MHz crystal manufactured by
Fox.
Note 2:
Reset delay is a synchronous counter of crystal oscillations after crystal startup. At 33MHz, this time is 1.99ms.
