CHAPTER 4 HOW TO USE MINICUBE2 WITH 78K0 MICROCONTROLLER

This chapter describes how to use MINICUBE2 when performing on-chip debugging and flash programming for a

78K0 microcontroller.

On-chip debugging is a method to debug a microcontroller mounted on the target system, using a debug function

implemented in the device. Since debugging is 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. Erasing, writing

and verifying 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 78K0 microcontroller as the target

device.

• 4.1 Target System Design

For communication between MINICUBE2 and the target system, communication circuits must be mounted on

the target system. This section describes the circuit design and mounting of connectors.

• 4.2 On-Chip Debugging

This section describes the system configuration and startup method to perform on-chip debugging with

MINICUBE2.

• 4.3 Flash Programming

This section describes the system configuration and startup method to perform flash programming with

MINICUBE2.
