• Start setup stage in UDC.
• Receive data in request normally and judge. And assert INT_SETUP
• Change data stage in the UDC.
• The CPU receives a request from the request register every INT_SETUP
• Judge request and access Setup Received register to inform the UDC that
• According to Device request, monitor EP0 bit of DATASET register, and write
• If the UDC is set data of payload to FIFO or CPU set short packet transfer in
• The UDC transfers data that is set to FIFO to host by IN token interrupts.
• When the CPU finishes transaction, it writes “0” to EP0 bit of EOP register.
• Change status stage in the UDC.
• Return ACK to OUT token, and change state to IDLE in the UDC.
• Assert INT_STATUS interrupt externally.
