setting. If a PWM change is programmed via the SPI when the
LEDxRAMP=0, then the change is immediate rather than
spread out over a PWM sweep.
the color mixing should be obtained by the current level setting
so that the intensity is set through the PWM duty cycle. In
addition, programmable blink rates are provided. Blinking is
obtained by lowering the PWM repetition rate of each of the
drivers through LEDxBLNK[1:0] while the on period is
determined by the duty cycle setting, default is 0.5 s ON time.
To avoid high frequency spur coupling in the application, the

switching edges of the output drivers are softened. During
blinking, so LEDxBLNK[1:0] is not "00", ramping and dimming
patterns cannot be applied.
LEDs they can also be used as general purpose open drain
outputs for logic signaling or as generic PWM generator
outputs. For the maximum voltage ratings see
