UDC_UsbReset_INT
Description
UDC_UsbReset Interrupt.
0 = UDC_UsbReset signal is not asserted.
1 = UDC_UsbReset signal is asserted.
The UDC_UsbReset signal is asserted by the UDC Core
whenever the core observes more than 2.5 us (32 FS bit
times/4 LS bit times) of SE0 on the D+/D- lines. Once
asserted, UDC_UsbReset is kept asserted as long as the SE0
is observed on the D+/D- lines.
UDC_Sof Interrupt.
0 = UDC_Sof signal is not asserted.
1 = UDC_Sof signal is asserted.

UDC_Sof_INT
The UDC_Sof signal is asserted by the UDC Core for one
clock every time an entire SOF Packet is successfully decoded
on the USB.
The UDC_Sof signal is at logic ‘0’ when Reset and when
asserted will be at logic ‘1’.
USB_SUSPEND_INT
USB Suspend Detected Interrupt.
0 = USB Cable not in Suspend Mode.
1 = USB Cable in Suspend Mode. UDC has detected that
the USB Cable is in the Suspended Mode i.e., the USB
is idle for 3 ms. The Device should go into SUSPEND
mode whenever this bit is on and should meet all the
USB Specification Requirements for the Suspend Mode.
It is the responsibility of the peripheral to stop the Clock
so that min. power is consumed when the Device is in
Suspended Mode.

USB_RESUME_INT
USB Resume Detected Interrupt.
0 = USB Cable not in Resume Mode.
1 = USB Cable in Resume Mode. UDC has detected a non-
IDLE (K State) on the USB Cable while the USB cable
is in Suspended Mode.
