Hybrid Dimming Diagram 7.3.8.6 Direct PWM Mode In direct PWM mode, all active channels are turned on and off and are synchronized with the input PWM signal. TON TPWM PWM Input D=100% D=80% D=60% D=50% D=25% 0A D=12.5% Direct PWM Mode D=6.25% ILED 100% ILED Figure 7-12. Direct PWM Dimming Diagram 7.3.8.7 Sloper An optional sloper function makes the transition from one brightness value to another optically smooth. By default the advanced sloper is enabled with a 200-ms linear sloper duration. Transition time between two brightness values is programmed with the SLOPE_SELECT[2:0] bits (when 000, sloper is disabled). With advanced sloper enabled the brightness changes are further smoothed to be more pleasing to the human eye. Advanced slope is enabled with ADV_SLOPE_ENABLE register bit.
