Disabling BDM interface on MCF5235

I use the BDM interface for debugging but when I am not debugging I would like to turn off the PST[0..3] and PSTCLK lines as these switch continually at up to the core frequency causing horrible emissions. I expect there is a way to disable these lines from the firmware but I haven't been able to find any information anywhere. Is there a way to do this?

Thanks
Scott
