BF70x SWD Interface

Hi all, 

 

Is there a way to use SWD-DP instead of JTAG-DP interface on BF706? I'm trying to reduce a few pins on my design to make the manufacturing process easier.

 

If so, how can I activate SWD mode? Will it be activated automatically if I only connect SWD pins and leave TDI unconnected? Do I need JTAG_nRST anymore or I can simply pull it up? Can I use only SWDCLK and SWDIO and leave SWO unused?
