6. For reference, under typical process, 25 °C temperature, and a voltage of 2.8 V, the voltage that would be seen at
7. 8.0-MHz XTAL1 input clock frequency with 4-MHz system clock
8. 8.0-MHz XTAL1 input clock frequency with 8-MHz system clock
voltage fluctuations are anticipated, such as those resulting from driving an infrared LED.
P31 under an input current of 10 uA or 100 uA would be ~480 mV or .560 mV, respectively.
