My memory of the 14 pin JTAG connector was of two different Vcc
connections. One provided power from the FET to the target while the
other was used to sense the Vcc level on the target and adjust signal
levels.

A quick check of slau278u shows two signals:

VCC_TOOL
VCC_TARGET

VCC_TOOL provides power to the target while VCC_TARGET is used to sense
the Vcc level.

Having an external power supply connected to VCC_TOOL is just asking for
trouble.
