ABSTRACT:
An LED driver pin which can be used for programming a memory element in a first mode, and can be used for driving the LED in a second mode is provided. The invention includes the pin and the LED driver connected to the pin, and additionally provides an input buffer for receiving the programmable input signal. The programmable memory element is connected to the input buffer, and a control circuit is provided for enabling the input of a voltage on the pin to the programmable memory element during the first mode, and enabling the LED driver to function during a second mode.
