3.3 Programming Adapter Target Connector Signals
The target connector signals for the programming adapter ensure
communication between the programming adapter and MSP430 devices and
supply low energy to systems without extra supply sources.
Figure 3−1 and Figure 3−2 show the target connector signals for the
programming adapter.
