16-bit Fm+ I2C-bus LED driver
7.3.6 LEDOUT0 to LEDOUT3, LED driver output state
LDRx = 00 — LED driver x is off (default power-up state).
LDRx = 01 — LED driver x is fully on (individual brightness and group dimming/blinking
not controlled).
LDRx = 10 — LED driver x individual brightness can be controlled through its PWMx
register.
LDRx = 11 — LED driver x individual brightness and group dimming/blinking can be
controlled through its PWMx register and the GRPPWM registers.
