In electronics a relaxation oscillator is a nonlinear electronic oscillator circuit that produces a nonsinusoidal repetitive output signal, such as a triangle wave or square wave.
The R&C have been chosen to make a ~2MHz signal. An inverter after the oscillator makes a full swing square wave.
Measure the oscillator out on pin 0 (tbc, might cause issues due to the analog mux parasitics). Measure the square wave out on digital output pin 0.
