Disconnecting the On-Board Debugger

The block diagram below shows all connections between the debugger and the PIC16F15376 microcontroller. The rounded boxes represent connections to the board edge on PIC16F15376 Curiosity Nano. The signal names shown in Figure 1 are printed in silkscreen on the bottom side of the board.

Figure 1. On-Board Debugger Connections to the PIC16F15376

By cutting the GPIO straps with a sharp tool, as shown in Figure 2, all I/Os connected between the debugger and the PIC16F15376 are completely disconnected. To completely disconnect the target regulator and level shifter power from the target, cut the Power Supply strap (J100) as shown in Figure 2.

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