Note 18: Startup time for a crystal varies with load capacitance and manufacturer. The time shown is for an 11.0592MHz crystal manufactured
by Fox Electronics.
Note 19: Reset delay is a synchronous counter of crystal oscillations after crystal startup. Counting begins when the level on the XTAL1 pin
meets the V_IH2 criteria. At 33MHz, this time is 1.99ms.
