Manufacturer:ROHM Description:Once the 8051 is in control, it can use advanced features of the SIE to simplify its USB firmware. Endpoint zero SETUP data is placed in a separate 8-byte RAM space for easy access. GET_Descriptor requests are simplified by using a special Setup Data Pointer. The 8051 simply loads a descriptor address into this 16-bit register, and the SIE takes care of the remaining overhead, i.e., dividing the descriptor into packets, sending them via endpoint 0 in response to IN tokens, and providing the necessary handshakes. The 8051 can do other chores while the SIE completes this USB transfer. |
