MSP430FR5994 LaunchPad™ Development Kit (MSP ‑ EXP430FR5994)
2.2.2 eZ-FET Onboard Debug Probe With EnergyTrace++ Technology
To keep development easy and cost effective, TI's LaunchPad development kits integrate an onboard
debug probe, which eliminates the need for expensive programmers. The MSP-EXP430FR5994 has the
eZ-FET debug probe (see Figure 5), which is a simple and low-cost debugger that supports all MSP430
device derivatives.

The MSP-EXP430FR5994 LaunchPad development kit features full EnergyTrace++ technology. The
EnergyTrace™ functionality varies across the MSP portfolio (see Table 1).

In Figure 5, the dotted line through J101 divides the eZ-FET debug probe from the target area. The
signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. For more
details on the isolation jumper block, see Section 2.2.3.
The eZ-FET also provides a "backchannel" UART-over-USB connection with the host, which can be very
useful during debugging and for easy communication with a PC. For more details, see Section 2.2.4.
Details of the eZ-FET hardware can be found in the schematics in Section 6 and in the hardware design
files download page. The software and more information about the debugger can be found on the eZ-FET
wiki.
