Functional Block Description
Command Processor
The command processor is the important block of device controller. It does the decoding and execution of all standard commands. It also maintains the device state machine and the handshake database for standard and vendor specific commands.

Control Endpoint
Endpoint controller has the control of all USB control transfers. It maintains the state machine for Setup, Data and Status stages of control transfers. Data toggle and handshakes for control transfers will be controlled in this module.

Endpoint FIFO
Every endpoint in the device controller has associated FIFO buffer for data transfer. The buffer size for each endpoint is configurable. 

Application Interface
The device controller has a generic application interface which can be used to interface different applications. E.g. Ethernet, serial port, parallel port

UTMI+/ULPI Interface
This interface is provided for external standard ULPI/UTMI+ PHY. This ULPI interface is a wrapper around UTMI+ interface. Any of the two interfaces can be used for external USB PHY
