    FX3 JTAG TCK pullup / pulldown

    pat.crowe

      The FX3 JTAG port has internal pullups of 50k on all connections except TCK which has a 10k pulldown, according to the data sheet.

         

      The FX3 devkit PCB has 10K pullup resistors on all these pins. Is the conflict on TCK intended? And if I want to use the same JTAG debug cable on my own board as on the devkit, is this arrangement what is required?
