Disconnecting the On-Board Debugger
The block diagram below shows all connections between the debugger and the PIC18F47Q10
microcontroller. The rounded boxes represent connections to the board edge on PIC18F47Q10 Curiosity
Nano. The signal names are shown in
and printed in silkscreen on the bottom side of the
board.

with a sharp tool, as shown in
, all I/Os connected between the
debugger and the PIC18F47Q10 are completely disconnected. To completely disconnect the target
regulator, cut the VTG strap shown in
