/**
* @file
*
* This file contains the data structures for accessing the DWC_otg core registers.
*
* The application interfaces with the HS OTG 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 HS OTG 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.
