For what CPU? Does your CPU support JTAG? If it is a real 68k (meaning MC68000) then that chip doesn't have a debug port.
If it is something like a 68306 then that chip has JTAG, but nothing in the manual documents its use for debugging.
The "USB BDM Multilink" mentioned ONLY works on the 6 pin debug connector on the Freescale HCS08, HC(S)12(X), RS08, and ColdFire V1 microcontrollers. It doesn't work on the V2, V3 or V4 ColdFire CPUs which have a 26-pin connector. For them you need the "USB Multilink Universal", as it supports Freescale HCS08, HC(S)12(X), S12Z, RS08, ColdFire V1/+V1, ColdFire V2-4*, Qorivva 5xxx, and Kinetis ARM microcontrollers (but costs $100 more at $199).
If you really mean "68k" and the only ones that can support JTAG debugging are the MC683xx series, then you need the 'USB Multilink Universal FX" which costs another $200 ($399):
There also seem to be older parallel port cables, but you have to get separate 3.3V and 5V ones, and then you have to find an old computer with a parallel port.
I don't believe that there are any help documents for the USB/BDM interface. It was developed by P&E Microcomputer Systems (www.pemicro.com), but it's just the interface from your IDE to the BDM header on your development board.
Is there something specific you want to know about the USB/BDM interface?
P&E does have documentation for all of the hardware interfaces. You need to go to our support -> "documentation & downloads" to find them.
Here is a link to all doc and downloads for the USB BDM Multilink:
