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

62  * don't have direct access to it. (We access it
63  * using usbd_do_request() when reading/writing
64  * registers.) Consequently, our endpoint indexes
65  * don't match those in the ADMtek Pegasus manual:
