Hi-Speed USB peripheral controller
Each interrupt bit can individually be cleared by writing logic 1. The DMA Interrupt bit can
be cleared by writing logic 1 to the related interrupt source bit in the DMA Interrupt
Reason register, followed by writing logic 1 to the DMA bit of the Interrupt register.
