EZ-0009 User's Manual

This chapter describes how to use EZ-0009 when performing on-chip debugging and flash

programming.

To perform on-chip debugging for uPD78F8025 microcontroller, a specific program (debug

function) must be downloaded to the microcontroller, and then debug the microcontroller

mounted on the target system.

Flash programming is a method to write a program to the flash memory embedded in a

microcontroller. Erasing and writing the program can be performed on-board with the

microcontroller.

This section describes the target system circuit design required for on-chip debugging and

flash programming.

Figure 3-1 present an overview of the EZ-0009-Emulator communication interface.

As shown on the figure, EZ-0009-Emulator performs serial communication with the target

microcontroller on the target system. For this communication, communication circuits must be

mounted on the target system. Refer to this section to design circuits appropriately.

* Communication circuits are mounted on Target board (QB-78F8025-TB)
