Dimming waveforms
Normal dimming mode
In normal timing mode the basic cycle is represented by a latency period followed by a
dimming period starting with the on-phase (current generators active). This option is
selected by clearing the DTIN (dimming timing inversion) bit of the DEVCGF1 register.
Figure 13. Normal timing mode waveforms
Inverted dimming mode
In inverted dimming mode, the basic cycle is represented by a latency period followed by a
dimming period starting with the off-phase (current generators turned off). This option,
normally used when a common turn-off is required, is selected by asserting the DTIN
(dimming timing inversion) bit of the DEVCGF1 register.
