

0: No UDP Resume Interrupt pending
1: UDP Resume Interrupt has been raised
The USB device sets this bit when a UDP resume signal is detected at its port.
After reset, the state of this bit is undefined, the application must clear this bit by setting the RXRSM flag in the UDP_ICR.



0: No Start of Frame Interrupt pending
1: Start of Frame Interrupt has been raised
This interrupt is raised each time a SOF token has been detected. It can be used as a synchronization signal by using iso-

chronous endpoints.



0: No End of Bus Reset Interrupt pending
1: End of Bus Reset Interrupt has been raised
This interrupt is raised at the end of a UDP reset sequence. The USB device must prepare to receive requests on the end-

point 0. The host starts the enumeration, then performs the configuration.



0: No Wakeup Interrupt pending
1: A Wakeup Interrupt (USB Host Sent a RESUME or RESET) occurred since the last clear.
After reset the state of this bit is undefined; the application must clear this bit by setting the WAKEUP flag in the UDP_ICR.
