Figure 4-2. Target System Stand-Alone Connection
For production boards, a further enhancement of this scheme would be to
include cutable traces between the pins of P1 and P2, as shown in Figure 4-2.
The traces may be cut when debugging is necessary. To return the board to
stand-alone use, jumpers may be installed as shown.
The circuit shown in Figure 4-3 intercepts the mode select and communication
signals for in-circuit debugging and programming.
