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. 47 */ 48 49 #define AUE_UR_READREG 0xF0 50 #define AUE_UR_WRITEREG 0xF1 51 52 #define AUE_CONFIG_INDEX 0 /* config number 1 */ 53 #define AUE_IFACE_IDX 0 54 55 /* 56 * Note that while the ADMtek technically has four endpoints, the control 57 * endpoint (endpoint 0) is regarded as special by the USB code and drivers 58 * don't have direct access to it (we access it using usbd_do_request() 59 * when reading/writing registers.
