Some microcontrollers like Arduino have very limited internal storage space ... Remember, to set the module’s device address, you only must connect the address pins to VCC or GND through the address ...

and no I/O pin. It only applies to certain microcontrollers, but he provides example Arduino code showing how handy this can be for battery-powered projects. The usual way to measure VCC is simple ...
