Honored ContributorWhy would you want to? The components are design to be interfaced from the JTAG port. Replacing the JTAG port with I/O pins that duplicate the function of the JTAG port is not very productive. You can control a USB-Blaster directly using FTDI's D2XX driver, so if your argument is that you want "total control" of the JTAG interface, I can help you with that.
