Section 20 USB Function Module (USB)
(3)
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 out-
transfer, the application waits for data from the host, and after data is received (EP0oTS bit in
IFR0 = 1), reads data from the FIFO. Next, the application writes 1 to the EP0o read complete bit,
empties the receive FIFO, and waits for reception of the next data.
The end of the data stage is identified when the host transmits an IN token and the status stage is
entered.
