7.3.1.2 Controlling LED Driver Output PWM

PWM can be controlled by either with program execution engines (1, 2 and 3) or via I2C registers (02h for B, 03h

for G, 04h for R and 0Eh for W).

Control of LED driver output PWM selection is managed with 2 bits for each LED output from register 70h. The

Table 3 describes the selection options. With these bits for example all LED outputs can be controlled from one

program execution engine.
