3.4 Disconnecting the On-Board Debugger

The following block diagram illustrates the connection between the debugger and the PIC32CM JH01 microcontroller. The oval boxes represent connections to the board edge on the PIC32CM JH01 Curiosity Nano+ Touch. The signal names are shown in the 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 PIC32CM JH01 can be disconnected. To disconnect the target regulator, the user need to cut the VTG strap.

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