4.1.4 Data Gateway Interface (DGI)

Data Gateway Interface (DGI) is a USB interface transporting raw and timestamped data between on-board debuggers and host computer-based visualization tools. MPLAB Data Visualizer is used on the host computer to display any debug GPIO data. It is available as a plug-in for MPLAB X IDE or a stand-alone application that can be used in parallel with MPLAB® X IDE.

Although DGI encompasses several physical data interfaces, the PIC16F17146 Curiosity Nano implementation includes logic analyzer channels:

One debug GPIO channel (also known as DGI GPIO)
