1284/1390
0: PMAOVR interrupt disabled.
1: PMAOVR interrupt enabled, an interrupt request is generated when the corresponding bit
in the USB_ISTR register is set.
0: ERR interrupt disabled.
1: ERR interrupt enabled, an interrupt request is generated when the corresponding bit in the
USB_ISTR register is set.
0: WKUP interrupt disabled.
1: WKUP interrupt enabled, an interrupt request is generated when the corresponding bit in
the USB_ISTR register is set.
0: Suspend mode request (SUSP) interrupt disabled.
1: SUSP interrupt enabled, an interrupt request is generated when the corresponding bit in
the USB_ISTR register is set.
0: RESET interrupt disabled.
1: RESET interrupt enabled, an interrupt request is generated when the corresponding bit in
the USB_ISTR register is set.
0: SOF interrupt disabled.
1: SOF interrupt enabled, an interrupt request is generated when the corresponding bit in the
USB_ISTR register is set.
0: Expected start of frame (ESOF) interrupt disabled.
1: ESOF interrupt enabled, an interrupt request is generated when the corresponding bit in
the USB_ISTR register is set.
0: LPM L1 state request (L1REQ) interrupt disabled.
1: L1REQ interrupt enabled, an interrupt request is generated when the corresponding bit in
the USB_ISTR register is set.
Software sets this bit to send a LPM L1 50 μs remote wakeup signaling to the host. After the
signaling ends, this bit is cleared by hardware.
0: No effect
1: Send 50 μs remote-wakeup signaling to host
