6.11.1 VBUS Generation

When the target AVR device is acting as an on-the-go master, it must supply VBUS voltage to the USB device it is controlling. To do so, place a jumper on the pin header (J901) next to the USB connector. The FET is controlled by the UVCON signal, also routed to the target AVR device.

When not using the VBUS generation feature, the jumper must be removed.

Note: VCC is 5.3V.
