• Host mode
Figure 32-3. Speed Selection in device mode
When the USBC interface is in host mode, internal pull-downs are enabled on both DP and DM.
The interface detects the speed of the connected device and reflects this in the Speed Status
field (USBSTA.SPEED).
Endpoints and pipe buffers can be allocated anywhere in the embedded memory (CPU RAM or
HSB RAM).
