Universal Serial Bus Interfaces
21.1.1
The USB DR 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. Each DR module is either a device or host controller.
The DR module supports the required signaling for UTMI low pin count interface (ULPI) transceivers
(PHYs). The PHY interfacing to the ULPI is an external PHY.
The DR module contains a chaining DMA (direct memory access) engine that reduces the interrupt load
on the application processor and reduces the total system bus bandwidth that must be dedicated to
servicing the USB interface requirements.
21.1.2
The USB DR module includes the following features:
21.1.3
The USB DR module operates in two modes: host and device.
21.2
This section contains detailed descriptions of all the USB controller signals.
21.2.1
The ULPI (UTMI low pin count interface) is a reduced pin-count (12 signals) extension of the UTMI+
specification. Pin count is reduced by converting relatively static signals to register bits, and providing a
bidirectional, generic data bus that carries USB and register data. This interface minimizes pin count
requirements for external PHYs.
