    Table 1. The J101 isolation block allows the user to connect or disconnect signals that cross from the XDS110-ET domain into the MSP432P401R target domain. This crossing is shown by the silkscreen dotted line across the LaunchPad development kit through J101. No other signals cross the domain, so the XDS110-ET can be completely decoupled from the MSP432P401R target side.
