Silicon Labs CP210x: What is the behavior of each pin when the USB cable is not connected, during enumeration, and during suspend?

CP21xx

The following table shows the state of each pin during POR (Power-on Reset), during enumeration, during normal operation, during suspend, and during USB cable unplugging.

Article header Please explain the behavior of each pin when the USB cable is not connected, during enumeration, and during suspend 2 1
Article header Please tell me the behavior of each pin when the USB cable is not connected, during enumeration, and during suspend 2 2

Note 1) Some PCs turn off the VBUS power supply when transitioning to suspend. In that case, the behavior is the same as when the USB cable is not connected.
Note 2) CP2102/9 cannot be changed.
