2. START-UP INSTRUCTIONS
2.1. INSTALLING THE EVALUATION DEVELOPMENT KIT (EDK)
Please refer to the quick start guide provided for initial installation of the EDK.
A copy of the quick start guide and other information relating to this EDK at:
http://www.eu.renesas.com/tools
Installing the EDK requires power and serial connection to a host computer.
2.2. SERIAL CONNECTION
The serial communications cable for connecting the EDK to a host computer requires 1:1 connectivity.
Figure 2-1 shows how to connect the EDK to a PC or notebook computer equipped with a nine pin D connector.

FIGURE 2-1: SERIAL CONNECTION TO PC/NOTEBOOK WITH DB-9 CONNECTOR (SUPPLIED)
2.3. POWER SUPPLY
The EDK hardware requires a power supply of +5V. Since total power consumption can vary widely due to external
connections, port states, and memory configuration, use a power supply capable of providing at least 500mA at +5V DC ±
5%.
The design is specified for evaluation of the microcontroller and so does not include circuitry for supply filtering/noise
reduction, under voltage protection, over current protection or reversed polarity protection. Caution should be used when
selecting and using a power supply.
The power connector on the EDK is a 2.5mm Barrel connector. The center pin is the positive connection.
FIGURE 2-2: POWER SUPPLY CONNECTION
Caution: Existing customers using E6000 products note that the polarity of this board is opposite to that for the
E6000. Use of the E6000 power supply with this board will damage both board and power supply.

4. EDK OPERATION
4.1. USER INTERFACE
The EDK provides two buttons for influencing the operation of the board. The purpose of each button is clearly marked next
to it. Refer to the board layout for positions (Section 3)
1. Reset Switch
This button provides the microcontroller with a reset pulse utilizing the built in power on reset control of the device.
2. NMI Switch
This button provides a de-bounced signal to the microcontroller for each operation of the button. There is no maximum
activation time for this button.
4.2. SERIAL INTERFACE
The serial port on the microcontroller directly supports three wire serial interfaces. Options are provided on the board for the
user to write handshaking routines using standard port pins.
4.2.1. CONNECTOR PIN DEFINITIONS
The EDK RS232 interface conforms to Data Communication Equipment (DCE) format allowing the use of 1-1 cables when
connected to Data Terminal Equipment (DTE) such as an IBM PC. The cable used to connect to the EDK will affect the
available board options. A fully wired cable can allow handshaking between the microcontroller and the host PC, subject to
setting the board options and the availability of suitable host software. Handshaking is not supported as standard on the
microcontroller so for normal use a minimal three-wire cable can be used. The minimum connections are unshaded in the
following table.

* Note: The device used to convert the RS232 serial information to logic signals for the microcontroller is limited to
120kBaud. The rates above this level can only be utilised if the user provides direct logic level communications.
The user may replace the HC49/U surface mounted AT cut crystal with another of similar type within the operating frequency
of the microcontroller device. Please refer to the hardware manual for the microcontroller for the valid operating range.
Alternatively the user may fit an oscillator module – or provide an external clock source. When providing an oscillator module
or external source it is highly recommended that the load capacitors for the AT crystal are removed from the PCB. These are
physically placed within the PCB outline of the oscillator module for easy location and to ensure they are removed when
using this option.
When changing the crystal frequency the pre-loaded debugging monitor will not function. In this situation the user is
responsible for providing code to evaluate the device away from the default operating speed.

sure that the alternate settings are made for the other peripheral options to avoid contentions on the board.
5.4. FLASH PROGRAMMING HEADER
The Flash Programming header is used with the Flash Debugging Module (FDM). The FDM is a USB based programming
tool for control and programming of Renesas microcontrollers, available separately from Renesas. This header provides
direct access for the FDM to control the EDK microcontroller.
To utilise this header the user must make the following changes to the board configuration.
1. Select the FDM header using CJ4-C as marked on the silk screen. Please refer to section 5.2.
5.5. EXTERNAL DEBUG HEADER
The External debug header may be used with the Renesas E10T Debugger, Renesas LEM Debugger or a third party
debugger.
The E10T and LEM are on-chip debug emulators available separately from Renesas.
This header provides direct access for the debugger to control the EDK microcontroller.
5.6. BOOT CONTROL
The EDK provides a jumper selection to place the microcontroller device into boot mode. This jumper link grounds the NMI
pin on the device.
Always remove the power from the EDK before moving this jumper to prevent unintended effects in the processor that may
prevent the programming function from completing successfully.

7. CODE DEVELOPMENT
7.1. HMON
7.1.1. M
ODE SUPPORT
The HMON library is built to support Normal Mode only.
7.1.2. BREAKPOINT SUPPORT
The monitor utilises the Address Break Controller for code located in ROM, allowing a single breakpoint to be set in the code.
Code located in RAM may have multiple breakpoints limited only by the size of the On-Chip RAM.
Due to a limitation of the internal address break controller, a breakpoint set in ROM will execute the instruction at the
breakpoint and stop on the subsequent op-code.
7.1.2.1.CODE LOCATED IN FLASH / ROM
Double clicking in the breakpoint column in the code sets the breakpoint. Adding a further breakpoint in the code removes
the previous one. A warning message will be displayed in the message window when this occurs.
7.1.2.2.CODE LOCATED IN RAM
Double clicking in the breakpoint column in the code sets the breakpoint. Breakpoints will remain unless they are double
clicked to remove them.
7.1.3. HMON CODE SIZE
HMON is built along with the debug code. Certain elements of the HMON code must remain at a fixed location in memory.
The following table details the HMON components and their size and location in memory. For more information, refer to the
map file when building code.

7.1.5. BAUD RATE SETTING
HMON has initially set to connect at 115200Baud. Should the user wish to change this, the value for the BRR in
HMONserialconfiguser.c will need to be changed and the project re-built. Please refer to the HMON User Manual for further
information.
7.1.6. INTERRUPT MASK SECTIONS
The EDK3687 has fixed interrupt priorities. The serial (SCI3 )port interrupt is used by HMON. The Real Time clock, external
interrupt and Timer V interrupts have a higher priority than the serial port. If these interrupts are used HMON may not
function correctly.
7.2. ADDITIONAL INFORMATION
