On-Board Debugger Implementation
PIC16F15376 Curiosity Nano features an on-board debugger that can be used to program and debug the
PIC16F15376 using ICSP. The on-board debugger also includes a Virtual Com port interface over UART and DGI
GPIO. Microchip MPLAB
®
X can be used as a front-end for the on-board debugger for programming and debugging.
Data Visualizer
can be used as a front-end for the CDC and DGI GPIO.

On-Board Debugger Connections
The table below shows the connections between the target and the debugger section. All connections between the
target and the debugger are tri-stated as long as the debugger is not actively using the interface. Hence there is little
contamination of the signals the pins can be configured to anything the user wants.
For further information on how to use the capabilities of the on-board debugger, see Section
3. Curiosity Nano
