Lpc2000

I just received the KickStart board from IAR and I'm running a little
program that toggles some output pins (blinky). Looking at then port
pins with a scope I see rise and fall time of 15 microseconds. Do I
have a broken part or what?

Thanks for you help.

They are left blank in the LPC210x data sheet, so they could be anything!

Yes, I noticed the data sheet was blank. I also looked a little closer
and saw that it wasn't all of the outputs that were slow. The problem
pin is po.16. po.17->19 are fast (10ns).

Maybe my part is broken.
