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 data status register is
referenced to confirm that the FIFO is empty, and then data is written to the FIFO.
