I have an AVR XMega-A1 Evaluation Board in front of me, which I can program over PDI using the ALL-AVR-Programmer.
I know that the PDI of the AVR XMega-A1 Evaluation Board uses the same pins with different labels for PDI and JTAG.
The following table extracted from the User Guide shows the PDI and JTAG labels of the Evaluation Board:
I have another IC -for the sake of clarity i will call this circuit Optimus-Prime-Board- in front of me which also has a JTAG interface and uses the ATxmega128A1 CPU. The JTAG interface is labelled in this fashion:
It is obvious to me that the Optimus-Prime-Board follows the standard layout of the JTAG interface and the AVR Xmega Eval Bord does not.
What I want to know is:
1.) I do not know wether or not the Optimus-Prime-Board has the ability to do PDI over the same pins in the fashion the XMega Eval-Board does. Is this ability something which is special to the Eval Board or does every IC in the world, which has a JTAG interface implicitly have PDI over the same pins?
2.) Can I program the Optimus-Prime-Board using PDI by connecting its pins 2 (GND), 3 (TDO), 6 (NSRST) and 7 (VSUPP) to the ALL-AVR-Programmer?
Thanks in advance
