UpBridge GPIO pin mappings?

gerfen

Referencing the documentation for the GPIO pin mappings from the UpBridge API to the physical GPIO pins on the 100 pin header:

The mapping shows 22 pins. When I enumerate the DIO pins via the UpBridge.Up like so:

var status = (GpioStatus) upBridge_.GpioGetCaps(0, out uint numberOfGpioPins, out uint disabled);

numberOfGpioPins equals 24. To which physical pins are the the extra 2 DIO pins mapped?

I received more information from AAEON tech support. DIO 23 and DIO 24 are used internally and therefore, should **not **be used in code.
