By cutting the GPIO straps with a sharp tool, as shown in Figure 3-5, all I/Os connected between the

debugger and the PIC16F18446 are completely disconnected. To completely disconnect the target

regulator, cut the VTG strap shown in Figure 3-5.

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.

Info:  Solder in 0Ω resistors across the footprints or short-circuit them with tin solder to

reconnect any cut signals.
