The status LED outputs are configured to be push outputs, therefore the LEDs should
be connected with common GND. Depending on the power supply voltage of the
PCA9555, the selected series resistance to the LEDs must meet the LEDs' and
PCA9555's maximum current requirements.
The following table shows the behavior of the different status LEDs that display
operating and battery status.
