NOTES FOR POWER CYCLE TIMING CHARACTERISTICS
1. Startup time for crystals varies with load capacitance and manufacturer. Time shown is for an 11.0592MHz
crystal manufactured by Fox crystal.
2. Reset delay is a synchronous counter of crystal oscillations after crystal startup. Counting begins when the
level on the XTAL1 input meets the V
IH2
criteria. At 25MHz, this time is 2.62ms.
