CAP1128

Bits 3 - 0 - DIR_OFF_DLY[3:0] - Determines the turn-off delay, as shown in Table 6-65, for all LEDs that are configured

to operate in Direct behavior mode.

The Direct behavior operation is determined by the combination of programmed Rise Time, Fall Time, Min and Max Duty

cycles, Off Delay, and polarity. Figure 6-7 shows the behavior for non-inverted polarity (LEDx_POL = 1) while Figure 6-

8 shows the behavior for inverted polarity (LEDx_POL = 0).
