pd 1k resistor pull-down to GND
pd* 1k resistor pull-down to GND to be added with a patch
pd+ 1k resistor pull-down all pd+ are connected to the same pull-down
LED plus resistor to 3V3 connected to GPIO54 on FX3 SuperSpeed Kit
The 1k value is low enough to be able to detect the resistor using the GPIO internal programmable pull-up pull-down vs a floating pin.
The value is high enough to not disturb use of GPIOs for other purpose after detection.
