Programming an MSP430F2102IPW using 2-wire SPY-BI-WIRE (SBW) interface.

I'm confused about which 2 pins are actually used for tying the clock and data lines to on an MSP430F2102IPW for programming using the 2-wire SBW interface.

This is the 20-pin TSSOP device which uses several shared pins for TDI and TCK.  The data sheet is not clear

about which pins should be used for connecting signals, SBWTDIO and SBWTCK.  I'm in PCB layout now and need to get this

right the first time.    Any help in clarifying this would be greatly appreciated.

Thanks in advance.
