White LED, PWM Drivers — I
2
C Registers
SLVS658B – MARCH 2006 – REVISED FEBRUARY 2007
The I
2
C registers that control LED AND PWM driver related functions are shown below. The HEX address for
each register is shown by the register name, together with the R or W functionality for the register bits. Shaded
values indicate default initial power-up values. In the equations replace Bn with 1 for HI state, and 0 for LO state.
