Designing Target System Circuits when Using V850E2S or V850E2M
To debug the target system with QB-V850MINIL or QB-V850MINI connected, a circuit to connect QB-V850MINIL or
QB-V850MINI is required on the target system.
This section presents information required for circuit design. Read this information together with the information
described in the user’s manual of the target device.
Note that circuit design information when the target device is the V850E2, V850E1, or V850ES is described in

3.4.1
Example of circuit design (for V850E2S or V850E2M)
Figure 3-5 illustrates an example of the design of a target system circuit that is used to connect QB-V850MINIL or
QB-V850MINI.
To determine the resistance value in the circuit, see the user’s manual of the target device.
