 **   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.

          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

          CSRs are classified as follows:
           - Core Global Registers
           - Device Mode Registers
           - Device Global Registers

           - Host Global Registers
           - Host Port CSRs
           - Host Channel Specific Registers

          Only the Core Global registers can be accessed in both Device andHost 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

		                                     transmit FIFOs and the receive FIFO are flushed.
		                                     The status mask bits that control the generation of
		                                     the interrupt, are cleared, to clear the
		                                     interrupt. The interrupt status bits are not
		                                     cleared, so the application can get the status of
		                                     any events that occurred in the core after it has
		                                     set this bit.
		                                     Any transactions on the AHB are terminated as soon
		                                     as possible following the protocol. Any
		                                     transactions on the USB are terminated immediately.
		                                     The configuration settings in the CSRs are
		                                     unchanged, so the software doesn't have to
		                                     reprogram these registers (Device
		                                     Configuration/Host Configuration/Core System
		                                     Configuration/Core PHY Configuration).
		                                     The application can write to this bit, any time it
		                                     wants to reset the core. This is a self clearing
		                                     bit and the core clears this bit after all the
		                                     necessary logic is reset in the core, which may
		                                     take several clocks, depending on the current state
		                                     of the core.
