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 VIH2 criteria. At 33MHz, this time is 1.99ms.
