The application first analyzes command data from the host in the setup stage, and determines the
subsequent data stage direction. If the result of command data analysis is that the data stage is in-
transfer, one packet of data to be sent to the host is written to the FIFO. If there is more data to be
sent, this data is written to the FIFO after the data written first has been sent to the host (EP0iTS
bit in IFR0 = 1).
The end of the data stage is identified when the host transmits an OUT token and the status stage
is entered.
Note: If the size of the data transmitted by the function is smaller than the data size requested by
Data Stage (Control-In)
the host, the function indicates the end of the data stage by returning to the host a packet
shorter than the maximum packet size. If the size of the data transmitted by the function is
an integral multiple of the maximum packet size, the function indicates the end of the data
stage by transmitting a zero-length packet.
