Addr. 41H 42H 43H 45H 46H 47H 48H 49H 4AH 4BH Register Memory Mapping Address+Remote_WakeUp register represents current address and remote wake-up function. The initial value is ²00000000² from MSB to LSB. Register Address R/W Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 01000010B R/W Address value Default value=00000000 Remote Wake-up Function 0: Not this function 1: The function exists Address+Remote_WakeUp Register STALL, Pipe_ctrl and Endpt_EN Registers PIPE register represents whether the endpoint corresponding is accessed by host or not. After ACT_EN signal being sent out, MCU can check which endpoint had been accessed. This register is set only after the time when host access the corresponding endpoint. STALL register shows whether the endpoint corresponding works or not. As soon as the endpoint work improperly, the bit corresponding must be set. Pipe_ctrl register is used for configuring IN (Bit=1) or OUT (Bit=0) pipe. The default is define IN pipe. Where Bit0 (DATA0) of the Pipe_ctrl register is used to setting the data toggle of any endpoint (except endpoint 0) using data tog- gles to the value DATA0. Once the user want the any endpoint (except endpoint 0) using data toggles to the value DATA0, the user can output a LOW pulse to this bit. The LOW pulse period must at least 10 instruction cycle. Endpt_EN register is used to enable or disable the corresponding endpoint (except endpoint 0). Enable Endpoint (Bit=1) or disable Endpoint (Bit=0). |
