I have a development board with a Connect EM with JTAG.

It’s specify on “Digi connect EM Hardware reference guide” that register Bit of GPIO-9 is PORTC3 or this Bit is a source interrupt (as specify on “BSP porting guide”).
Is someone try to configure GPIO-9 as interrupt?
I try to use NAInstallIsr to configure an ISR application on this but didn’t manage to obtain a result.

Thanks for your answers


Here is an example program which configures PORTC3 as a high-to-low transition interrupt enabled GPIO pin.


Perfect, thanks for the help Cameron.
