— Supports enhanced host controller interface (EHCI)
• Supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) operation. Low
speed is only supported in host mode.
• Supports external PHY with ULPI (UTMI + low-pin interface)
• Supports operation as a standalone USB device
— Supports one upstream facing port
— Supports three programmable, bidirectional USB endpoints
• Host and device support
• OTG (on-the-go) support, which includes both device and host capability, with external PHY
(ULPI)
16.1.3 Modes of Operation
The USB DR module has three basic operating modes: host, device, and OTG. The module can be
configured to use one of two different PHY interfaces: ULPI or UTMI.
Only high-speed and full-speed operations are supported in device mode.
16.2 External Signals
This section contains detailed descriptions of all the USB dual-role controller signals. Many of the
signals for the PHY interfaces are muxed onto the same pins in order to reduce pin count.
describes the signals, indicating which interface supports each signal.
