 Again, set PIO 0 and PIO 1 to all four combinations of logic 0 and 1. Note which combinations turn on the LED. The voltage at the LED and Q<sub>5</sub> collector resistor can be monitored with the CH-B scope input as before. You can also use the CH-B ( and / or CH-A ) input to monitor the voltages at the collectors of Q<sub>1</sub> – Q<sub>4</sub> as you change PIO 0 and 1. Again, set PIO 0 and PIO 1 to all four combinations of logic 0 and 1.
