Each RGB2 pin (RED2, GREEN2 or BLUE2) will sink the current selected by RGB2_ISET[2:0], set in RGB2_RED register. The RGB2 does not support a flashing mode, and will be turned on when RGB2_EN is 1. When turned ON the duty cycle for each driver can be set individually using control bits PWMIR[4:0], PWMIG[4:0] and PWMIB[4:0] on registers RGB2_RED, RGB2_GREEN and RGB2_BLUE. The modulated output is not a single pulse of the selected duty cycle but a collection of semi-equally spaced pulses that sum to the required duty cycle, with repetition rate of 160Hz (typ). The start of one of the modulated pulses on RGB2 can be phased by 200 s from the others, so that for duty cycles below 50% the ON times of 2 of the LEDs will not overlap. When RGB2_PHASE is 0 (RGB2_GREEN[6]), the Red and Blue drivers are in phase and Green is out of phase. When RGB2_PHASE is 1 the Red and Green are in phase and Blue is out of phase.
