No, it is part of 1 of 4 interrupts configuration, if 1 of these interupts are enabled and used by hardware interrupt request, then CPU goes to that interrupt function and executes it, and I need to figure out how to write this function. Rockchip is like a computer CPU, like Pentium 1 at least
By the way, if you dont know how to use the DEC values, or asign them with the rockchip CPU datasheet file, I made a simple explanation in attachment, it whill be intresting for everyone.
