Planning to use the UMulitlink for debugger probe on my K64 board.

Universal Multilink Development Interface|NXP

Here is the schematics following the K64 Tower board.

But on the document below:

The 20-pin connector is showing like:

My question is

pin 9 is ground on the probe definition but on the tower board schematic is left going nowhere. Do I have to ground pin 9? or it doesn't matter.

 

Thanks.
