/**
|
|
* @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.
