I am designing a board around the ATxmegaXXXA3 series and am curious about the correct way to hook up the programming/debugging interfaces.
I looked at the Xplain board and it seems as though the JTAG and PDI share a connector. Is this correct:
nSRST = !RESET/PDI_Clock
nTRST = PDI_Data
If this is not correct I will create a separate connector for PDI. But in that case what do I hook to nSRST and nTRST?
I have looked through the app notes and manuals and couldn't really find a answer. Maybe one of you know where I could look?
