** 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

CSRs are classified as follows:

- Device Endpoint Specific Registers
- Host Mode Registers
- Host Global Registers
- Host Port CSRs

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
must be reprogrammed as they would be after a power-on reset.

The application can flush the control logic in the

pipelines in the AHB Clock domain as well as the
PHY Clock domain.
The state machines are reset to an IDLE state, the
control bits in the CSRs are cleared, all the
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.
