Chapter 2. Purpose
This RSK is an evaluation tool for Renesas microcontrollers.
This manual describes the technical details of the RSK hardware. The Quick Start Guide and Tutorial Manual provide details of the
software installation and debugging environment.
Features include:
• Renesas Microcontroller Programming.
• User Code Debugging.
• User Circuitry such as Switches, LEDs and potentiometer.
• User or Example Application.
• Sample peripheral device initialisation code.
The RSK board contains all the circuitry required for microcontroller operation.

Chapter 3. Power Supply
3.1. Requirements
This RSK operates from a 5V power supply.
A diode provides reverse polarity protection only if a current limiting power supply is used.
All RSK boards are supplied with an E10A debugger.
All RSK boards have an optional centre positive supply connector using a 2.0mm barrel power jack.
Warning
The RSK is neither under nor over voltage protected. Use a centre positive supply for this board.
3.2. Power – Up Behaviour
When the RSK is purchased the RSK board has the ‘Release’ or stand alone code from the example tutorial code pre-programmed into the
Renesas microcontroller. On powering up the board the user LEDs will start to flash. After 200 flashes, or after pressing a switch the LEDs
will flash at a rate controlled by the potentiometer.

6.5. Debug LCD Module
A debug LCD module is supplied to be connected to the connector marked ‘LCD’, so that the debug LCD module lies over J2. Care should
be taken to ensure the pins are inserted correctly into LCD. The debug LCD module uses a 4 bit interface to reduce the pin allocation. No
contrast control is provided; this is set by a resistor on the supplied display module. The module supplied with the RSK only supports 5V
operation.

Crystal (X1) Fitted 12.0 MHz (HC49/4H package)
Crystal (X2) Fitted 32.768 KHz
Table 6-13: Oscillators / Resonators
6.8. Reset Circuit
The CPU Board includes a simple latch circuit that links the mode selection and reset circuit. This provides an easy method for swapping
the device between Boot Mode and User mode. This circuit is not required on customer’s boards as it is intended for providing easy
evaluation of the operating modes of the device on the RSK. Please refer to the hardware manual for more information on the
requirements of the reset circuit.
The Reset circuit operates by latching the state of the boot switch on pressing the reset button. This control is subsequently used to
modify the mode pin states as required.
17
The mode pins should change state only while the reset signal is active to avoid possible device damage.
The reset is held in the active state for a fixed period by a pair of resistors and a capacitor. Please check the reset requirements carefully
to ensure the reset circuit on the user’s board meets all the reset timing requirements.
6.9. USB port
This RSK has a Full-speed (12 Mbps) USB port compliant to USB 2.0 specification. It is available as J12 on the RSK. This port allows Boot
mode programming using USB Direct connection. For more details please refer to H8SX/1668R Group Hardware Manual.
18
Chapter 7. Modes
This RSK supports two Boot modes and Single Chip mode.
Details of programming the FLASH memory is described in the H8SX/1668R Group Hardware Manual.
7.1. Boot mode
The boot mode settings for this RSK are shown in Table 7-1: Boot Mode pin settings below:
EMLE MD2 MD1 MD0 PM2 LSI State after Reset End
0 0 1 0 0 SCI boot mode
0 0 1 0 1 USB boot mode
Table 7-1: Boot Mode pin settings
The software supplied with this RSK supports debugging with E10A which does not need Boot mode. To enter the Boot mode manually, do
not connect the E10A in this case. Press and hold the SW1/BOOT. The BOOT LED will be illuminated to indicate that the microcontroller is
in boot mode.
SCI boot mode: boot mode executes programming/erasure of the user MAT or user boot MAT by means of the control command and
program data transmitted from the externally connected host via the on-chip SCI_4.
USB boot mode: executes programming/erasing of the user MAT by means of the control command and program data transmitted from the
externally connected host via the USB.
7.2. Singe chip mode
This is default operating mode of this RSK. Refer to H8SX/1668R Group Hardware Manual for details of Single chip mode. The Single chip
mode settings for this RSK are shown in Table 7-2: Single chip mode pin settings below:
EMLE MD2 MD1 MD0 LSI State after Reset End
0 1 1 1 Single chip Mode
Table 7-2: Single chip Mode pin settings
Programming/erasure of the user MAT is executed by downloading an on-chip program. The user boot MAT cannot be
programmed/erased in user program mode.
19
Chapter 8. Programming Methods
The board is intended for use with HEW and the supplied E10A debugger. Refer to H8SX/1668R Group Hardware Manual for details of
programming the microcontroller without using these tools. Please note that to use E10A debugger, jumper E10A_EN (J15) must be
fitted.

Chapter 10. Code Development
10.1. Overview
Note: For all code debugging using Renesas software tools, the RSK board must be connected to a PC USB port via an E10A. An E10 A
pod is supplied with the RSK product.
10.2. Compiler Restrictions
The compiler supplied with this RSK is fully functional for a period of 60 days from first use. After the first 60 days of use have expired, the
compiler will default to a maximum of 64k code and data. To use the compiler with programs greater than this size you need to purchase
the full tools from your distributor.
Warning: The protection software for the compiler will detect changes to the system clock. Changes to the system clock back in time may
cause the trial period to expire prematurely.
10.3. Mode Support
HEW connects to the Microcontroller and programs it via the E10A. Mode support is handled transparently to the user.
10.4. Breakpoint Support
HEW supports breakpoints on the user code, both in RAM and ROM.
Double clicking in the breakpoint column in the code sets the breakpoint. Breakpoints will remain unless they are double clicked to remove
them.
