Note: This flowchart shows just one example of interrupt transfer processing. Other possibilities include an
EP3 Interrupt-In Transfer
operation flow in which, if there is data to be transferred, the EP3 DE bit in the USB data status register
is referenced to confirm that the FIFO is empty, and then data is written to the FIFO.
