2.4.1
eZ-FET USB Power
The most common scenario is power from USB through the eZ-FET debugger. This provides 5-V power
from USB and also regulates this power rail to 3.3 V for eZ-FET operation and 3.3 V to the target side of
the LaunchPad. Power from the eZ-FET is controlled by jumper J13. For 3.3 V, ensure that a jumper is
connected across the J13 "V+" terminal. The eZ-FET is a debugger, so J10 must be set to debugger for
power to reach the target MSP430FR5969 device.

2.4.2
14-Pin JTAG
When powering directly from the JTAG connector through the MSP-FET430UIF or other MSP430
debugger tool, ensure that jumper J10 is set to "Debugger." JTAG debugging can also be used with an
external power source, when J10 is set to "External," and some external power source is connected
through J12. In this case the JTAG debugger will sense the external power and debug the system without
providing its own power.
