Universal Serial Bus Interface
24.2
The MCF5253 implements a USB OTG module. This module may be connected to one of two external
ports. Collectively the module and external ports are called the USB interface. The USB interface is shown
in
24.3
The module is a USB 2.0-compliant serial interface engine for implementing a USB interface. The
registers and data structures are based on the Enhanced Host Controller Interface Specification for
Universal Serial Bus (EHCI) from Intel Corporation. The module can act as a host, as a device, or as an
On-The-Go (OTG) negotiable host/device on the USB bus.
