I’m using a Signalyzer-h4 to connect to my target device through jtag, but I notice it has many unused pins marked as gpio capable in any mode. I can’t seem to find any information on how to use these pins. I’m interested in using them to just hold high/low/ slow clocking, or set one to mirror tdo and read additional registers output at the same time by my device. I’ve tried emailing the signalyzer people but haven’t gotton any response, was wondering if anyone else was using this dongle or if anyone had any ideas or experience with similar situations?
