• 4 - RXRSMI - Upstream Resume Received Interrupt
Set by hardware when an Upstream Resume has been received from the Device.
Shall be cleared by software. Setting by software has no effect.
• 3 - RSMEDI - Downstream Resume Sent Interrupt
Set by hardware when a Downstream Resume has been sent to the Device.
Shall be cleared by software. Setting by software has no effect.
• 2 - RSTI - USB Reset Sent Interrupt
Set by hardware when a USB Reset has been sent to the Device.
Shall be cleared by software. Setting by software has no effect.
• 1 - DDISCI Device Disconnection Interrupt
Set by hardware when the device has been removed from the USB bus.
Shall be cleared by software. Setting by software has no effect.
• 0 - DCONNI - Device Connection Interrupt
Set by hardware when a new device has been connected to the USB bus.
Shall be cleared by software. Setting by software has no effect.
• 7 - Reserved
The value read from these bits is always 0. Do not set these bits.
• 6 - HWUPE - Host Wake-Up Interrupt Enable
Set this bit to enable HWUP interrupt.For correct interrupt handle execution, this interrupt should
be enable only before entering power-down mode.
Clear this bit to disable HWUP interrupt.

Set this bit to enable HSOF interrupt.
Clear this bit to disable HSOF interrupt.
• 4 - RXRSME -Upstream Resume Received Interrupt Enable
Set this bit to enable the RXRSMI interrupt.
Clear this bit to disable the RXRSMI interrupt.
• 3 - RSMEDE - Downstream Resume Sent Interrupt Enable
Set this bit to enable the RSMEDI interrupt.
Clear this bit to disable the RSMEDI interrupt.
