ADSP-SC58x USB Register Descriptions
LPM Interrupt Enable Register
The register enables the link power management (LPM) related interrupts. When an interrupt is
USB_LPM_IEN
enabled in this register and the corresponding interrupt is pending in USB_LPM_IRQ, the USB controller gener-
ates the interrupt. When an interrupt is disabled in this register, the corresponding interrupt may be pending in
USB_LPM_IRQ, but the USB controller does not generate an interrupt.
