Hello,
I will use a xds560v2 for three c6671s.
TDO and TDI of JTAG are connected as daisy-chain and the other JTAG signals(TMS, TCK, TRST) and 19 emu lines are connected in parallel to each c6671. I referred to Figure 24. Multiple Device - Parallel Trace Configuration of document SPRU655I.
According to datasheet, c6671 has 19 emu ports
I am not sure whether all 19 emu ports should be connected or just few emu ports are required.
Should I connect all emu ports?
