APPARATUS AND METHODS FOR EXTERNAL PROGRAMMING OF PROCESSOR OF LED DRIVER

摘要

External programming of at least one processor (30) of a LED driver (10). In a normal operation mode a first control input (22B/22C) of the LED driver (10) may be provided to a first processor input of the processor and a second control input (22B/22C) of the LED driver may be provided to a second processor input of the processor (30). In a programming mode the first and second control inputs (22B, 22C) may be provided to programming inputs of the processor (30) to thereby enable programming of the processor (30) via the first and second control inputs (22B, 22C).

1. A method of programming a processor of a LED driver, comprising:
directing, in a normal operation mode, a first control input of said LED driver to a first processor input of said processor and a second control input of said LED driver to a second processor input of said processor; receiving a programming signal; entering a programming mode in response to said programming signal; and directing, in said programming mode, said first control input to a third processor input of said processor and said second control input to a fourth processor input of said processor; wherein said third processor input and said fourth processor input are programming inputs.
