S3C2410A
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.
