On the TI am3335x processor, the physical i/o pins are muxed to different internal registers.
I can read the state of these internal registers, but what I would like to do is read the state on the physical output of the mux instead, so that I can know the state of the connection to the outside world regardless of which mux channel is selected. Are there any registers for each mux output? I can't find any info on that. Is it even possible on the am3335x, or do I have to check the state of the internal registers for the mux-mode that is selected at the time, to know the state at the output of the mux?
