Note 1: Startup time for crystals varies with load capacitance and manufacturer. Time shown is for an 11.0592MHz crystal manufactured by Fox
Electronics.
Note 2: Reset delay is a synchronous counter of crystal oscillations during crystal startup. Counting begins when the level on the XTAL1 input
meets the V_IH2 criteria. At 40MHz, this time is approximately 1.64ms.
