The device has a RGB LED, which has two states for each "sub-LED",
|
|
on and off.
|
|
The "sub-LEDs" are red, green and blue.
|
|
|
|
Obviously there are 8 possible combinations for their state.
|
|
It seems there aren't bits mapped to each sub-LED, but instead
|
|
3-bit values mapped to the 8 combinations.
