Universal Serial Bus (USB) Controller
The Stellaris^® USB controller electrical specifications are compliant with the Universal Serial Bus
Specification Rev. 2.0 (full-speed and low-speed support). Some components of the USB system
are integrated within the LM3S5P3B microcontroller and specific to the Stellaris microcontroller
design. An external component resistor is needed as specified in Table 25-31.
