8.4 Disconnecting the On-Board Debugger
The on-board debugger and level shifters can be completely disconnected from the PIC18F16Q40.
The block diagram below shows all connections between the debugger and the PIC18F16Q40. The rounded boxes represent connections to the board edge. The signal names shown are also printed in silkscreen on the bottom side of the board.
To disconnect the debugger, cut the straps shown in Figure 8-6.
Attention: Cutting the GPIO straps to the on-board debugger will disable the
virtual serial port, programming, debugging, and data streaming. Cutting the power
supply strap will disconnect the on-board power supply.
Tip: Any connection that is cut
can be reconnected using solder. Alternatively, a 0Ω 0402 resistor can be
mounted.
Tip: When the debugger is
disconnected, an external debugger can be connected to holes shown in Figure 8-6. Details about connecting an external debugger are
described in Connecting External Debuggers.
