I notice that in the schematics for the STEVAL-LLL007M1, part of the evaluation kit for the LED1202, several of the A0 pins for the attached LED1202s are pulled to ground with 10K resistors. However, in the datasheet for the LED1202 the example schematics do not show such an arrangement.
What is the purpose of the 10K pull down resistor? And is it necessary in other designs using the LED1202?
-A
