Command Based Pattern Generator for Color LEDs
The LP3952 has an unique stand-alone command based pattern generator with 8 user controllable 16-bit commands. Since reg-
isters are 8-bit long one command requires 2 write cycles. Each command has intensity level for each LED, command execution
time (CET) and transition time (TT) as seen in the following figures.

COLOR INTENSITY CONTROL
Each color has 3-bit intensity level. Level control is logarith-
mic, 2 curves are selectable. The LOG bit in register 11H
defines the curve used as seen in the following table.
R[2:0], G[2:0],
B[2:0]
