Simplified Device Data Structures for the High-End ColdFire Family USB Modules by: Melissa Hunter Applications Microcontroller Solutions Group
Some of the high-end ColdFire products (such as the MCF532x, MCF537x, MCF5253, and MCF5445x devices) contain an EHCI-patible host or dual-role/OTG USB controller. The dual-role module can be used as a USB host, a USB device, or as an On-the-Go device. When the dual-role module is used as a device, it uses data structures to control USB data movement. These data structures are similar in some ways to the embedded host controller interface (EHCI)...
