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.
