In my XBS I have a signal that I’d like to use as a interrupt source to CPU.
I’m able to connect it to the D2 board pin and use this pin as interrupt source
for programs in Arduino IDE.
But I’d like to use an internal path from my XBS and CPU, no board pins.
In openxlr8.v I find the xlr8_pcint instantiation, where
.x_int_in (), // INSERT YOUR XB INTERRUPTS HERE
I suppose I have to put my signal here
but I don’t know ho to write the related interrupt service
in the Arduino program.
