Dear sir,
I have a question about VBUS terminal processing for PSOC4L.
When using the DP/DM ports in this device as GPIO (not using USBFS), can I leave VBUS open? Or should it be fixed to VDD?
I thought that if these ports for USBFS were completely separated from VDDIO, they might not function as GPIO unless VBUS was applied.
Is it correct to understand that the DP/DM port can be used as GPIO without depending on VBUS processing?
Best regards,

- When using the DP/DM ports in this device as GPIO (not using USBFS), can I leave VBUS open?
A. Yes, it should work fine.
- Is it correct to understand that the DP/DM port can be used as GPIO without depending on VBUS processing?
A. Yes, it could be used as GPIO, and it's described theGPIO drive mode for DM and DP in Resister TRM.
You can refer to the section "41.1.3 USBDEVv2_USB_USBIO_CTRL" in 001-98126 Rev. *C.
