Sounds exactly like the Cypress part. That suggests that it's probably
a wash.

I'm currently playing with the Cypress development board with the
intention of prototyping the gTAG device, so I (and Stefan and WW)
already have some time invested in this choice, not to mention my
external motivations. (Full disclosure, folks:-)

When the next project starts up, we may choose to revisit this choice
with what will then be more experienced insight. At any rate, thanks
for the tip.
