H8SX Family Emulator E6000H
Usage of Realtime RAM Monitoring
REJ06J0024-0100/Rev.1.00 July 2007 Page 2 of 23
1. Specifications
The E6000H emulator provides the RAM monitoring function to display the memory contents during realtime
execution of the user program. In this monitoring function, the realtime operation is retained since the bus monitoring
circuit of the emulator sets the read/write signal of the MCU as a trigger and holds the address bus and data bus values
to update the displayed contents of memory.
Up to eight points or 256 bytes in total can be set by using the eight monitoring channels on the bus monitoring
circuit. It is possible that a part or all of monitoring ranges is overlapped.
Notes:
1. Monitoring is impossible for an area, such as an on-chip timer counter, where no internal write signal is
generated to update a value.
2. The procedure to display or modify the contents of memory differs depending on the product. If the
display of memory contents is updated during execution of the user program, realtime emulation may not
be available. For details, refer to section 5.4, Displaying and Modifying the Contents of Memory, in the
H8SX E6000H Emulator User's Manual.
2. Functional Descriptions
This document describes how to use the RAM monitoring function in the H8SX/1651 E6000H emulator.
It guides you through examples of the setting of the realtime RAM monitoring function in the sample program
provided in the CD-ROM of the H8SX E6000H emulator. Check that the memory contents have been changed on the
[Monitor] window during program execution.
3. Software Preparation
3.1 Introduction
Install the software provided in the CD-ROM of the H8SX E6000H emulator to expand the sample program (tutorial
workspace) to be used in this document on your personal computer.
The software in the CD-ROM of the H8SX E6000H emulator can also be installed in a personal computer in which
the High-performance Embedded Workshop has already been installed. In this case, some dialog boxes may be skipped
in the installation process.
If the software has already been installed, go to section 4.
