Stop current bias program resistor.
Tail current duty cycle PWM program resistor.
Ground if using external modulation.
Channel 8 constant current output to LED.
Unused pin should be grounded.
Channel 7 constant current output to LED.
Unused pin should be grounded.
Channel 6 constant current output to LED.
Unused pin should be grounded.
Channel 5 constant current output to LED.
Unused pin should be grounded.
Ground.
Channel 4 constant current output to LED.
Unused pin should be grounded.
Channel 3 constant current output to LED.
