S3C2440A RISC MICROPROCESSOR USB DEVICE INTERRUPT ENABLE REGISTER (EP_INT_EN_REG/USB_INT_EN_REG) Corresponding to each interrupt register, The USB device controller also has two interrupt enable registers (except resume interrupt enable). By default, usb reset interrupt is enabled. If bit = 0, the interrupt is disabled. If bit = 1, the interrupt is enabled.
