Interface MCU power

The power for the interface MCU is routed through two load switches, one for the VDD supply and one for the USB supply. This makes it possible to disconnect the interface MCU from the power domain when it is not in use.

These switches are controlled by the presence of a USB connected to the interface MCU USB connector (J2), and the state of the interface MCU disable switch (SW6). See Operating modes for more information.
