36  * Register definitions for ADMtek Pegasus AN986 USB to Ethernet
37  * chip. The Pegasus uses a total of four USB endpoints: the control
38  * endpoint (0), a bulk read endpoint for receiving packets (1),
39  * a bulk write endpoint for sending packets (2) and an interrupt
40  * endpoint for passing RX and TX status (3). Endpoint 0 is used
41  * to read and write the ethernet module's registers. All registers
42  * are 8 bits wide.
43  *
44  * Packet transfer is done in 64 byte chunks. The last chunk in a
45  * transfer is denoted by having a length less that 64 bytes. For
46  * the RX case, the data includes an optional RX status word.

56  * Note that while the ADMtek technically has four endpoints, the control

58  * don't have direct access to it (we access it using usbd_do_request()
59  * when reading/writing registers.  Consequently, our endpoint indexes
60  * don't match those in the ADMtek Pegasus manual: we consider the RX data
61  * endpoint to be index 0 and work up from there.
