Yes, I did misunderstand.  So I can plug the AVRISPmk2 into the header for
straight programming, or plug the JTAGmk2 into the same header for in-chip
debugging?  If so, are there any limitations on in-chip debugging via a PDI
2-pin header versus a separate JTAG 4-pin header?   Steve

I think you misunderstood John's reply

You can do debugging over PDI, just not with the AVRISPmk2.
The Atmel JTAGmk2 can debug over PDI. (and JTAG, obviously). But you only
need 2 pins for PDI.
