Command Based Pattern Generator for Color LEDs
The LP3954 has a unique stand-alone command based pattern generator with 8 user controllable 16-bit wide
commands. Since write registers 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). The command structure is
shown in following two figures.
