17.4.1.7
The USB module provides a single-chip solution for USB device applications that are self-powered or
bus-powered. The USB device needs to know when it has a valid USB connection in order to enable or
disable the pullup resistor on the USBDP line. For the USB module on this device, the pullup on USBDP
is only applied when a valid VBUS connection is sensed, as required by the USB specification.
In bus-powered applications, system power must be derived from VBUS. Because VBUS is only available
when a valid USB connection from host to device is made, the VBUS sensing is built-in, and the USBDP
pullup can be enabled accordingly.
With self-powered applications, determining when a valid USB connection is made is different from that
of bus-powered applications. In self-powered applications, VBUS sensing must be built into the
application. For instance, a KBI pin interrupt can be utilized (if available). When a valid VBUS connection
is made, the KBI interrupt can notify the application that a valid USB connection is available, and the
internal pullup resistor can be enabled using the USBPU bit. If an external pullup resistor is used instead
of the internal one, the VBUS sensing mechanism must be included in the system design.
