3. On-Chip Debugging
This chapter describes how to use QB-V850MINIL or QB-V850MINI when performing on-chip debugging (OCD).
On-chip debugging is a method to debug a microcontroller mounted on the target system. Since debugging is
performed with the real device operating on the board, this method is suitable for field debugging.
On the other hand, on-chip debugging takes up five or six function pins for communication with the host machine.
Moreover, communication circuits must be mounted on the target system.
Refer to 3.4 Designing Target System Circuits when using V850E2S or V850E2M, and for the latter, refer to 3.5
Designing Target System Circuits when using V850E2, V850E1, or V850ES for information on designing target
system circuits. Also refer to the user's manual for the target device.
Refer to 3.6 Target Connectors for OCD for the target connectors for OCD that can be mounted on the target board.
