NOTES FOR POWER CYCLE TIMING CHARACTERISTICS
1.
Start-up time for crystals varies with load capacitance and manufacturer. Time shown is for an
11.0592 MHz crystal manufactured by Fox Electronics.
2.
Reset delay is a synchronous counter of crystal oscillations during crystal start-up. Counting begins
when the level on the XTAL1 input meets the V
IH2
criteria. At 40 MHz, this time is approximately
1.64 ms.
