BDM meets JTAG

Here’s my dilemma:

I have a Multilink Universal for my JTAG device.
Telephone support tells me I need to be using
Port C of this device (a 2x3 6-pin arrangement) that
uses BDM.

The XBee S2C processor (surface mount) has JTAG pins I need to connect to.

Does anyone know the proper mappings of connecting BDM to JTAG?

Many thanks!!!
