Schmitt buffer input; low selects Grayscale register, high selects Brightness Control register; do not change while SCLK is high. |+| 4 | OUT0 | output | Constant current sink output; 50 mA maximum capability with 16-bit grayscale PWM control and 7-bit global brightness control. |+| 5 | OUT1 | output | Constant current sink output;
