/*
D10 has 3 led values
0/0 - Upper indicator Green
1/1 - Upper indicator Orange
2/9 - AF
10-11 appears to also drive AF, but using the same codepath as non AF leds (no assert on invalid)
note, LEDDrive returns 3 on invalid params otherwise 0
second param 0 = solid on, 1 = off, 2-7 blink patterns
2: continuous ~1 blink/sec
3: continuous fast blink
4: continuous medium blink (2/sec ?) 
5: burst of 3? fast blinks
6: continuous slow blinks
7: if led was off 1 very fast blink. depends on previous state
8: no obvious effect, but returns 0 for AF
>8: If used with AF ASSERT!! LEDDrv.c Line 215, otherwise returns 3
