LED6_LOG_EN
0
R/W
This bit is effective for both, program execution engine and
direct PWM control.
0: linear adjustment.
1: logarithmic adjustment.

LED6_TEMP_COMP
0 0000
R/W
The reference temperature is +25°C (i.e. the temper ature at
which all slope settings have no effect) and the temperature
coefficient (slope) can be set in 0.1 1/°C steps to any value
between -1.5 1/°C and +1.5 1/°C, with a default to 0.0 1/°C
11111: -1.5 1/°C
11110: -1.4 1/°C
...
00000: temperature compensation not activated
...
01110: +1.4 1/°C

LED7_MAPPING
00
R/W
This register defines the mapping of LED7 output to the master
faders. The faders can either be used for dimming several
LEDs in parallel or for ratiometric control of the output.
00: no master fader selected
01: MASTER FADER 1 controls LED7 output
10: MASTER FADER 2 controls LED7 output
11: MASTER FADER 3 controls LED7 output
