The application is expected to write the data packets into the transmit FIFO when the
space is available in the transmit FIFO and the Request queue up to the count
specified in the MCNT field before switching to another channel. The application uses
the NPTXFE interrupt in OTG_FS_GINTSTS to find the transmit FIFO space.
