CHAPTER 5 HOW TO USE MINICUBE2 WITH 78K0S MICROCONTROLLER

This chapter describes how to use MINICUBE2 when performing on-chip debugging and flash programming for
a 78K0S microcontroller.
To perform on-chip debugging for a 78K0S microcontroller, a specific program (debug function) must be
downloaded to the device, and then debug the device mounted on the target system.
performed with the target device operating on the board, this method is suitable for field debugging.
Flash programming is a method to write a program to the flash memory embedded in a device.
writing the program can be performed on-board with the device.
Read the following chapters if you are using MINICUBE2 for the first time with a 78K0S microcontroller as the
target device.
• 5.1
Target System Design
