    PSoC5LP : USBFS component suspend operation

    MaMi_1205306

      Hi,

       

      We are considering USBFS component for PSoC5LP.

      Coded according to "USBFS_suspend" in Code Example.

       

      Sleeps PSoC 5LP when there is no signal from the host for 3ms.

      Wake up at the fall of USBIF Dp.

      It works as expected.

       

      However,

      When the PC host side stops power supply and opens the USB signal line,

      The USBIF Dp line voltage becomes unstable and PSoC5LP repeatedly wakes up and sleeps.

       

      Do you know how to avoid this sleep and wake up behavior?

       

      Regards,
