PROGRAMMING EXAMPLES
Set 18 mA current at Bank LEDA
Set 20 mA current at LEDA, 18 mA at LEDB, and 15 mA at LEDC
banks (assuming address at 00h and consecutive writes)
Turn LEDs A1, B1 and C1 on, all others off
Turn LEDs A2, B2, and C2 on, all others off
Turn all LEDs on
Decrease brightness at 50% (-6 dB) at all three channels
simultaneously (in logarithmic mode only)
Decrease brightness at 75% (-12 dB) at all three channels
simultaneously (in logarithmic mode only)
Restore full brightness at all three channels simultaneously
Set Bank B PWM duty Cycle at 50% (-6 dB) in logarithmic mode
Set Bank B PWM duty Cycle at 50% in linear mode
Short/open LED diagnostic request
Read out LED short to GND status
Read out LED short to V
Set WLED Mode with 1 PWM generator in linear mode, soft start
disabled, and LP standby mode
Set Standby Mode
Resume normal operation from standby mode
Calibration request (conduct temperature calibration; wait >=16ms)
Set LEDs in shutdown mode at temperature above 85
Set 2-x scale de-rating at temperature equal or above 55
Software Reset (to default values) and/or clear of all registers
