Use MC9S12DT256 atd pins as digital outputs?

Hi all,

 

I'm having a bit of trouble navigating the modular documentation for the MC9S12DT256 -- it is very hard to be sure you *can't* do something when you have to search a dozen places, so I thought I'd ask here before I concluded negatively.

 

Is it possible to use the PADxx/ANxx pins on the MC9S12DT256 as digital outputs?  It seems clearly easy to me to use them as digital inputs, but I can't find the "DDR" register to turn them into outputs!

 

Can someone point me to where I should look in the doc, or what register names I should use in the headers?

 

Thanks!!!

PS I now have StickOS (MCU-Resident Rapid Prototyping and Education Environment from the canyourbadgedothis.com contest!) running on 9S08 and 9S12 (minus the 9S12 pin controller, obviously, which should be done tomorrow) -- it is very exciting to run on the new MCUs!
