What sort of bicolor LED is it? 2 legs or three? Are green and amber
mutually exclusive, or can you control them independently? If they are
independent, then you can represent it as two LEDs. If the colours are
mutually exclusive its a different story.

Two legs, mutually exclusive.

Oh, unusual, there is a datasheet:

That is not like Broadcom.

Thank you, this is a great find! I hadn't spotted this when I started
looking into the platform. I will digest a bit more but so far it
looks like the pins are independent but setting both wouldn't work
with a 2-pin LED.
