MSP430FR2476 LaunchPad™ Development Kit (LP ‑ MSP430FR2476)
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 LP-MSP430FR2476 has the eZ-
FET debug probe (see
Figure 5 ), which is a simple and low-cost debugger that supports all MSP430™
device derivatives.

The LP-MSP430FR2476 LaunchPad development kit features EnergyTrace technology but does not have
support for Ener+ technology. The EnergyTrace technology functionality varies across the MSP
portfolio (see
Table 1 ).

The dotted line through J101 shown in Figure 5 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 on this connection, see
Section 2.2.4 .
The eZ-FET hardware schematics are available in Section 6 and in the hardware design files download
page . For more information on the software and the debugger, visit the eZ-FET wiki .
