not check the “Power Target from emulator” checkbox.

Double click the download module and download the sample code (the sample

code can also be downloaded through the Flash Development Toolkit).

After closing the High-performance Embedded Workshop, unplug the USB cable from the board.

Running the Sample Code

Set DIP switch SW2 as follows: 1 = ON, 2 = OFF, 3 = OFF, 4 = OFF.

After connecting the USB cable to the board and pressing the Reset Switch, the sample code downloaded to the MCU will

be executed.

First, the LEDs will start blinking. LED blink speed is controlled by the AN0 pin connected to potentiometer RV1 on-board. To

Setting Up the Development Environment

Create the necessary environment before evaluating the sample code.

1. Download and install the latest versions of the software below from the Renesas website: http://www.renesas.com/e8a .

Install the C compiler package before installing the E8a emulator debugger.

[Evaluation Software] M16C Series, R8C Family C Compiler Package M3T-NC30WA

R8C E8a Emulator Debugger

[Evaluation Software] Flash Development Toolkit

2. Download the board schematics, device placement diagram, and sample code workspace (zip file) from the Renesas

website: http://www.renesas.com/rpbr8cm12a .

change the blinking speed, adjust the RV1 control knob on the potentiometer. At the same time, as the blinking pattern is

recorded, the A/D conversion value is written to the data flash. The LEDs stop blinking after 200 times.

Pushing SW1 will cause the LEDs to blink in the pattern (A/D conversion value) written to the data flash in Step 14. The

LEDs stop blinking after 200 times.

After the blinking is finished, the sample code will run the power control demo. LED0 will turn on, and the MCU will enter

standard operating mode. Current consumption in standard operating mode is between 3 mA and 7 mA (see Note 1).

By pressing SW1 again, the MCU enters wait mode, and LED1 will turn on. Current consumption in wait mode is between 15

uA and 100 uA (see Note 1).

By pressing SW1 again, the MCU enters stop mode, and LED2 will turn on. Current consumption in stop mode is between 1

uA and 4 uA (see Note 1).

Downloading the Sample Code

Note 1. Remove R22 from the board and connect ammeter across J3 to measure current.
