7.3.1.1 Direct drive mode

The direct drive mode can drive up to 4 LEDs (or 1 RGBW / RGBA / RGBY LED) by the internal constant current sinks directly, when the 'led_mode' bit is 0h. The typical application circuit is illustrated in Figure 7-3. Each current sink can support up to 51 mA maximum current. In the register map, LED_x (x = 0, 1, 2, 3) are used as the name of each outputs for the related settings.
