3.4 Disconnecting the On-Board Debugger

The following block diagram shows connections between the debugger and the PIC32CM5164LS00048 microcontroller. The oval boxes represent connections to the board edge on the PIC32CM LS00 Curiosity Nano+ Touch. The signal names are shown in following figure and printed in silkscreen on the bottom side of the board.

Figure 3-4. On-Board Debugger Connections

By cutting the GPIO straps with a sharp tool, as shown in the following figure, all I/O connected between the debugger and the MCU can be disconnected. To disconnect the target regulator, cut the VTG strap.

Note:
  • Cutting the connections to the debugger will disable programming, debugging, and data streaming. The signals will also be disconnected from the board edge next to the on-board debugger section.
  • Solder 0Ω resistors across the footprints or short-circuit traces with tin solder to reconnect any cut signals.
