M16C

Target Setup for the FoUSB Programmer

1.0 Abstract

The ICD (In-Circuit Debugger), or USB-Monitor, is a low cost, compact interface that has two functions for

Renesas’ M16C Flash microcontrollers: 1) an in-system programmer with FoUSB (Flash-over-USB

) Flash

Programmer, and 2) an in-circuit debugger tool with KD30 Debugger. The following article introduces, and

shows examples of, how to configure the target hardware with Renesas’ M16C Flash MCU to interface with the

ICD for in-system programming.

2.0 Introduction

When used with the FoUSB Flash Programmer, the ICD provides an in-system programming interface to the

target Renesas M16C Flash MCU. In addition, when used with KD30, it also provides an easy-to-use in-circuit

debugging environment during application development.

The ICD, by taking advantage of Universal Serial Bus (USB), provides plug-and-play connectivity and fast data

transfers between the computer and the M16C target board. The ICD is powered by Renesas’ M37641 full speed

USB Flash MCU, which also makes it upgradeable to support future Renesas M16C MCUs.

Powering the ICD is user selectable: USB Bus powered or Target powered. When used in bus-powered mode,

the USB bus supplies power to the ICD and target board. When in target-powered mode, USB bus power is

disconnected and the ICD sources power from the M16C target board. Renesas recommends to use Target

Power Mode and NOT USB Bus Power Mode when connected to non-Renesas SKP target boards. If you plan to

use the ICD to supply power to non-SKP boards, please contact Renesas representative for details and

assistance.

Aside from a standalone kit (RTA-FoUSB-MON), the ICD comes included with the following Renesas Starter

Kits:

• MSV30102-SKP

• MSV30262-SKP

• MSV30245-SKP

• M16C System Evaluation Kit

• SKP16C26

• SKP16C28

• SKP16C62P

• SKP8CMini

The ICD requires 5V for re-programming if a new MCU file (MMI) needs to be downloaded to the ICD (i.e. when the target MCU selected does not match the MCU file on the ICD). To accomplish this, disconnect the ICD from the target, set to Bus Power Mode, and then download new MCU file. After MCU file has been downloaded, switch back to Target Power Mode. 3.

This must be connected to the target MCU’s boot UART/SIO receive data input (RXD) pin.

This must be connected to the target MCU’s CNVss pin. During normal operation, this pin must have a low signal. To accomplish this, connect a 10K (nominal) pull-down resistor. See M16C MCU datasheet on CNVss pin description for details. 3.
