DATASHEET

Bits 2 - 0 - DIR_OFF_DLY[2:0] - Determines the Direct behavior mode turn-off delay, which is the

amount of time an LED in Direct behavior mode remains active after it is no longer actuated (such as

after a release has been detected or the drive state has been changed). Available settings are shown

in Table 6.89.

The Direct behavior operation is determined by the combination of programmed Rise Time, Fall Time,

and Off Delay as shown in Figure 6.7 (non-inverted polarity LEDx_POL = 1) and Figure 6.8 (inverted

polarity LEDx_POL = 0).
