    Abstract: A microcontroller includes an input pin and internal pull-up and pull-down circuits. External pull-up and pull-down circuits are also coupled to the input pin. The microcontroller is operable according to different configuration modes which include configuring the input pin in a floating state. A control logic then configures the internal pull-up and pull-down circuits according to an internal pull-up mode to acquire a first input voltage signal (at a first logic value) from the input pin, and further configure the internal pull-up and pull-down circuits according to an internal pull-down mode to acquire a second input voltage signal (at a second logic value) from the input pin. A selection of the operating mode of the MCU is then made based on the acquired first and second logic values.

    Abstract: A power supply system includes a voltage application source, and a switched mode power supply having an output coupled to the voltage application source through a first path and through a second path different from the first path. A first node is coupled to the output of the switched mode power supply, the switched mode power supply being configured to couple the first node to the voltage application source through the first path in a first operating mode and through the second path in a different second operating mode. A digital regulator is coupled to the first node. A digital circuit is coupled to an output of the digital regulator. An analog regulator is coupled to the first node and an analog circuit coupled to an output of the analog regulator.
