DATASHEET
Each port’s indicator must be located in a position that obviously associates the indicator with the port. The
color and state of the LED is used to provide status information to the user.
Two different modes of operation are supported for the port indicators: automatic mode and manual mode.
The USB20H04 defaults to automatic mode upon power-up. In automatic mode, the USB20H04 controls
the color of the indicator LED as described in Table 7.1 - Automatic Mode Port Indicators.
