This example demonstrates the usage of interrupts and sleep modes. In this use case, the microcontroller exits sleep on button press, turns on an LED, and goes back to sleep. On button release, it exits sleep, turns off the LED, and goes back to sleep. The LED is ON while the button is pressed, but the microcontroller can be in sleep mode.
