    Hello,

    When the device starts up the default value for all of the LEDs is for them to be in the OFF state with none of the LED channels sinking current.
    See Table 6 in Section 9.5.3.

    Then looking at Section 9.3.3 in the section discussing POR it states that when the TLC59116 experiences a POR all of the channels are deselected and they return to their default state which is off.
