+ **   FILE NAME       : ifxusb_regs.h
+ **   PROJECT         : IFX USB sub-system V3
+ **   MODULES         : IFX USB sub-system Host and Device driver
+ **   SRC VERSION     : 3.2
+ **   DATE            : 1/Jan/2011
+ **   AUTHOR          : Chen, Howard
+ **   DESCRIPTION     : This file contains the data structures for accessing the IFXUSB core
+ **                     registers.
+ **                     The application interfaces with the USB core by reading from and
+ **                     writing to the Control and Status Register (CSR) space through the
+ **                     AHB Slave interface. These registers are 32 bits wide, and the
+ **                     addresses are 32-bit-block aligned.
+ **                     CSRs are classified as follows:
+ **                     - Core Global Registers
+ **                     - Device Mode Registers
+ **                     - Device Global Registers
+ **                     - Device Endpoint Specific Registers
+ **                     - Host Mode Registers
+ **                     - Host Global Registers
+ **                     - Host Port CSRs
+ **                     - Host Channel Specific Registers
+ **
+ **                     Only the Core Global registers can be accessed in both Device and
+ **                     Host modes. When the USB core is operating in one mode, either
+ **                     Device or Host, the application must not access registers from the
+ **                     other mode. When the core switches from one mode to another, the
+ **                     registers in the new mode of operation must be reprogrammed as they
+ **                     would be after a power-on reset.
