Silicon Labs CP210x: I want to operate other than CP210x with power supply from USB. In that case, how should Max Power be set?

CP21xx

There is a Max Power setting in the CP210x ROM, but please set the total current value you get from the USB.
For example, in the case of the figure below, 500mA of power is received from the USB Host, 100mA is used by the CP210x, and 400mA is used by the external circuit. The current consumption of the CP210x is 100mA, but the total power supply to the device is 500mA, so Max Power is set to 500mA.
