has anyone experience with emulating more than one ATMEGA in a JTAG chain?
I use 5 pcs. of ATMEGA 64 in a JTAG-chain. Now I want to debug these controllers (one after another) with the ATJTAGICE. In the AVRSTudio I can set any options (Debug / JTAG ICE Options / Connection). There I can check the box "Target device is part of a JTAG daisy chain". If I activate this option I have to define 4 values about the devices before and after my target and about the instructions bits before and after. Here is my problem. I have only 5 ATMEGAs in the JTAG chain. But what are the values for the the instruction bits febore and after? I cannot found any hint in the datasheet. Can anyone help me??
Thank you very much for your help. With best regards and the best wishes for a good and peaceful year 2004!
