Vbus interrupt in USB model of STM32F723

[Alexander_Aisin]

  I just got a STM32F723 board to learn how to use USB model, and I found that when I use USB as FS host and connect a device, the register PCDET did not triger an interrupt while PENA is set, I'm wondering how can I get interrupt flag, is there any other regs to set

Hi @Alexander_Aisin

PENA bit does not trigger an interrupt to the application. Did you follow the procedure to initialize the host as it is? I suggest you carefully read the reference manual!
