3.6 Disconnecting the On-Board Debugger

The on-board debugger and level shifters can be disconnected from the PIC32CM3204GV00064 microcontroller. The power supply block diagram (Figure 4-4) shows all connections between the debugger and the PIC32CM3204GV00064 microcontroller. The signal names are printed in silkscreen on the bottom side of the board. To disconnect the debugger, cut the GPIO straps as shown in Figure 3-3.

Note:
  • Cutting the connections to the debugger will disable programming, debugging, and data streaming. The signals will 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.
