nRF5340: Interrupt on VBUS detection

[gocchan]

Hi, 

I want to get the VBUS input detection status (USB detected or removed).

I have confirmed that the current state can be known by reading the value of the register USBREGSTATUS.

Is there a way to detect state changes and raise an interrupt event?

HW: nRF5340 (PCA10095)

NCS: ver. 2.2.0

You can just use the USB device controller status callback, which can be set via usb_dc_set_status_callback(...) function. The callback will get the USB_DC_CONNECTED and USB_DC_DISCONNECTED events.

Thank you.

I was able to get VBUS events by using usb_dc_attach() and usb_dc_set_status_callback().
