The hardened JTAG/I C programming architecture of the MachXO5T-NX Development Board is shown in
board has a built-in download controller for programming the LFMXO5-100T device. It uses an FT2232H Future
Technology Devices International (FTDI) part U1 to convert USB to JTAG from port A, or convert USB to I
Using Detect Cable function with Radiant programming software installed, you can detect dual ports after power up
the board and connect the mini USB to USB-A cable from J11 to your PC,ensuring FTDI reset control jumper JP9 is not
populated as default. The software select option FTUSB-0 is dedicate for hard JTAG and FTUSB-1 is dedicated for hard
