When the USB cable is pulled out, pin VBUSDET_N goes HIGH, thereby indicating to
the microcontroller that USB is disconnected. See
When the USB cable is plugged in, pin VBUSDET_N goes LOW. This indicates to the
microcontroller that the USB cable is plugged in. The microcontroller can then prepare
to reconfigure all registers of the ISP1183. See
