Hi all,
In STM32 USB device, there is an internally connected EXTI_Line18 for USB interrupt. When USB is connected to HOST, an interrupt is generated on this line. Is there a way of sampling the status of this line? I would like to monitor this as gpio input and see if it is in high or low state. Can this be done? If yes, which port is this i/o connected to? Thank you.
