Dedicated port charging detection
The STG3220 has a built-in dedicated port charging detection circuit to detect the condition
when the USB D+/D- lines are both in high state. When this occurs, the device sends an
interrupt signal to the processor to indicate that the connected USB device is in dedicated
port charging mode.
