In the alternate general-purpose ADC mode (with current source disabled), the input is pulled down to the ground. | |||
In this case, a logic zero corresponds to the floating input, while logic high corresponds to the voltage across terminals higher than 2.5V. | |||
In this mode one should connect external buttons, sensors, etc. between the Rx terminal and either "5V out" or positive power supply terminal. | |||
