5.13.3 Run Considerations

When running your program, consider that MPLAB X IDE operation connects to the hardware tool at runtime (Run or Debug). Consequently, settings made in MPLAB X IDE are passed to the tool only at runtime. Settings changed during a halt are updated only when runtime is initiated again.

To always be connected to the hardware tool (like MPLAB IDE v8), see Tools > Options (MPLAB X IDE > Preferences for macOS), Embedded > Generic Settings, Maintain active connection to hardware tool checkbox.
