Precautions
This Evaluation Kit is only intended for use in a laboratory environment under ambient temperature and humidity conditions. A safe separation distance
should be used between this and any sensitive equipment. Its use outside the laboratory, classroom, study area, or similar such area invalidates conformity
with the protection requirements of the Electromagnetic Compatibility Directive and could lead to prosecution.
The product generates, uses, and can radiate radio frequency energy and may cause harmful interference to radio communications. There is no guarantee
that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, which can be
determined by turning the equipment off or on, you are encouraged to try to correct the interference by one or more of the following measures:
• Ensure attached cables do not lie across the equipment.
• Reorient the receiving antenna.
• Increase the distance between the equipment and the receiver.
• Connect the equipment into an outlet on a circuit different from that whic h the receiver is connected.
• Power down the equipment wh en no t i n use.
• Consult the dealer or an experienced radio/TV technician for help.
Note: It is recommended that wherever possible shielded interface cables are used.
The product is potentially susceptible to certain EMC phenomena. To mitigate against them it is recommended that the following measures be undertaken:
• The user is advised that mobile phones should not be used within 10 m of the product when in use.
• The user is advised to take ESD precautions when handling the equipment.
The Evaluation Kit does not represent an ideal refe ren c e design for an end product and does not fulf ill the regulatory standards for an end pr oduct.

3. Overview of the Quick Start Example Project
The Quick Start example project allows the user to change the frequency and intensity of the on-board user
LEDs (LED1, LED2, and L ED3) using the user buttons (S1 and S2). The supported frequencies are 1 Hz,
5 Hz, and 10 Hz and the supported intensities are 10%, 50% and 90%.
When the EK-RA6M3 board running the Quick Start example project is connected to a host PC vi a USB as a
Full Speed CDC Device, the kit information, MCU die temperature, user LED blinking frequency, and so
forth, can be displayed on a terminal console.

5.4 Setting Up De bug Connection between the EK-RA6M3 board and Host PC
To program the modified Quick Start example project on to the EK-RA6M3 board, a debug connection is
necessary between the EK-RA6M3 board and host PC.
1. Disconnect the USB cable from micro-AB USB Full Speed port (J11) and connect it to micro-B USB
debug port (J10) of the EK-RA6M3 board.
Note: The EK-RA6M3 board supports 3 debugging modes. In this section and the following sections, default
debugging mode, Debug On-Board, is used. More information on debugging modes is available in
EK-RA6M3 user’s manual.
Figure 21. Connecting the EK-RA6M3 Board to the Host PC via USB Debug Port
2. Verify that the debug LED (LED5) stops blinking and lights up orange indicating that the J-Link drivers are
detected by the EK-RA6M3 board.
Note: The debug LED (LED5) continues to blink when J-Link drivers are not detected by the EK-RA6M3
board. In that case, make sure that the EK-RA6M3 board is connected to the host PC through the
micro-B USB debug port (J10) and that J-Link drivers are installed on the host PC by checking in the
Windows Device Manager (expand Universal Serial Bus controller, and locate J-Link driver)
