Switch channel to high-resistance (Tristate)
Each channel can be switched individually in high-resistance mode via index 0x80n0:0B (Tristate).
This state ensures that the respective output behaves as if it were not connected. This means that the outputs of other outputs/devices that are connected in parallel with these are not affected. The associated output takes on the same output voltage as the other active devices.
If the output is in Tristate mode, the respective Tristate LED lights up yellow.
