Figure 3.16.21 Flow of control in Control-WR transfers (with DATA-Stage)
the figure is not issued. Also, the "NYET" packet is replaced by the "ACK" packet.
To be processed in the same way as in the SETUP-Stage described in (1).
When the data is received from the host with no problem, UDC2 asserts the
EP0_DATASET flag and asserts the INT_EP0 flag. When this flag is asserted, read the
data from EP0_FIFO after confirming the received data size in the EP0_Datasize
register, or read the data from EP0_FIFO polling the EP0_DATASET flag.
When the byte size of received data has been read, UDC2 deasserts the EP0_DATASET
flag.
To be processed in the same way as in the STATUS-Stage described in (1).
