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) 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
LM3S5D91 microcontroller and specific to the Stellaris microcontroller design. An external component
resistor is needed as specified in Table 25-31.
