Claim:
1. A Light-Emitting Diode (LED) driver system comprising: a plurality of LED strings, each LED string of the plurality of LED strings being associated with a respective channel of a plurality of channels; and a Serial Lighting Interface (SLI) bus including a plurality of registers, the plurality of registers being serially connected together in a daisy chain, each respective register of the plurality of registers being configured to store data that includes channel data identifying a channel address, function data identifying a function of a plurality of functions to execute at the channel address, and function value data identifying a value of the function, the SLI bus being constructed to serially shift the function value data through the plurality of registers at a first rate, load the function value data into at least one latch at a second rate that is less than the first rate to change the value of the function in the respective channel responsive to the channel address corresponding to the respective channel and the function data corresponding to a supported function of a plurality of supported functions included in the plurality of functions, and leave the value of the function unchanged responsive to at least one of the channel address not corresponding to the respective channel and the function data not corresponding to any one of the plurality of supported functions.
