* Register definitions for ADMtek Pegasus AN986 USB to Ethernet
|
|
* chip. The Pegasus uses a total of four USB endpoints: the control
|
|
* endpoint (0), a bulk read endpoint for receiving packets (1),
|
|
* a bulk write endpoint for sending packets (2) and an interrupt
|
|
* endpoint for passing RX and TX status (3). Endpoint 0 is used
|
|
* to read and write the ethernet module's registers. All registers
|
|
* are 8 bits wide.
|
|
*
|
|
* Packet transfer is done in 64 byte chunks. The last chunk in a
|
|
* transfer is denoted by having a length less that 64 bytes. For
|
|
* the RX case, the data includes an optional RX status word.
