The way your post reads (at least to me) is that the "dedicated" 4 pins are in the plug.
Of course to include JTAG you need the JTAG pins on the chip. You do state the "disaster" from not dedicating them which several mfgrs have tried. My readings of the Philips ARM posts show that, in the philips case, you do not lose the reprogramming ability, but using these pins as other functions and starting debug creates havoc. Even more, why would you waste more silicon for the JTAG state machine and registers, if you would not use it for automated testing? is it a "waste" that you can debug, if you can not do "automated testing"?

| the debug/programming is nonstandard so | 01/01/70 00:00 | |
