The Stellaris^® USB controller DC electrical specifications are compliant with the “Universal Serial
Bus Specification Rev. 2.0” (full-speed and low-speed support) and the “On-The-Go Supplement
to the USB 2.0 Specification Rev. 1.0”. Some components of the USB system are integrated within
the LM3S5652 microcontroller and specific to the Stellaris microcontroller design. These components
are specified in Table 22-8 on page 786.
