Chapter 3. Power Supply
3.1. Requirements
This CPU board operates from a 5V power supply.
A diode provides reverse polarity protection only if a current limiting power supply is used.
All CPU boards are supplied with an E8 debugger. This product is able to power the CPU board with up to 300mA. When the CPU board is
connected to another system, that system should supply power to the CPU board.
All CPU boards have an optional centre positive supply connector using a 2.0mm barrel power jack.
Warning
The CPU board is neither under not over voltage protected. Use a centre positive supply for this board.
3.2. Power – Up Behaviour
When the RSK is purchased the CPU 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. Pressing switch 2 will cause the LEDs to flash at a rate
controlled by the potentiometer.

6.3. Potentiometer
A single turn potentiometer is connected to AN0 of the microcontroller via R42. This may be used to vary the input analog voltage value to
this pin between AVCC and Ground.
6.4. Serial port
The microcontroller programming serial port (SCI2) is connected to the E8 connector by default. SCI0 is connected to the 9-way D-type
connector labelled J8 via a RS232 transceiver.

Warning: When replacing the default oscillator with that of another frequency, the debugging monitor will not function unless the following
are corrected:
• FDT programming kernels supplied are rebuilt for the new frequency
• The supplied HMON debugging monitor is updated for baud rate register settings.
The user is responsible for code written to support operating speeds other than the default. See the HMON User Manual for details of
making the appropriate modifications in the code to accommodate different operating frequencies.
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, User 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.
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 USB port on the RSK. This port is used
by HMon to perform Boot Mode programming when a valid monitor is not detected on the microcontroller. This port also allows Boot mode
programming using USB Direct connection and FDT which does not require E8. For more details please refer to H8S/2215 Group
Hardware Manual.
17
Chapter 7. Modes
The CPU board supports User mode and Boot mode. User mode may be used to run and debug user code, while Boot mode may only be
used to program the Renesas microcontroller with program code via the USB interface. To program the user flash, the device must be in
Boot mode. Further details of programming the flash are available in the H8S/2215 Group hardware manual.
When using the E8 debugger supplied with the RSK the mode transitions are executed automatically. The CPU board provides
the capability of changing between User and Boot / User Boot modes using a simple latch circuit. This is only to provide a
simple mode control on this board when the E8 is not in use.
Do not use the Boot Latch function while the E8 is connected.
To manually enter boot mode, press and hold the SW1/BOOT. The mode pins are held in their boot states while reset is pressed and
released. Release the boot button. The BOOT LED will be illuminated to indicate that the microcontroller is in boot mode.
More information on the operating modes can be found in the device hardware manual.
7.1. FDT Settings
In the following sections the tables identify the FDT settings required to connect to the board using the E8Direct debugger interface. The ‘A’
interface is inverted on the RSK board. This is to ensure the board can function in a known state when the E8 is connected but not
powered. The E8 Debugger contains the following resistors.
E8 Pin Resistor
A Pull Down (100k)
B Pull Up (100k)
C Pull Down (100k)
D Pull Up (100k)

7.1.2. User Mode
For the device to enter User Mode, reset must be held active while the microcontroller mode pins are held in states specified for User Mode
operation. 100K pull up and pull down resistors are used to set the pin states during reset.
The H8SX/2215R supports four user modes. The memory map in all of these modes is 16Mbyte in size. The default user mode for CPU
board supporting H8S2215R is mode 7.

Chapter 8. Programming Methods
All of the Flash ROM on the device can be programmed when the device is in Boot mode. Once in boot mode, the boot-loader program
pre-programmed into the microcontroller executes and attempts a connection with a host (for example a PC). On establishing a connection
with the microcontroller, the host may then transmit program data to the microcontroller via the appropriate programming port.

Chapter 10. Code Development
10.1. Overview
Note: For all code debugging using Renesas software tools, the CPU board must either be connected to a PC serial port via a serial cable
or a PC USB port via an E8. An E8 is supplied with the RSK product.
The HMON embedded monitor code is modified for each specific Renesas microcontroller. HMON enables the High-performance
Embedded Workshop (HEW) development environment to establish a connection to the microcontroller and control code execution.
Breakpoints may be set in memory to halt code execution at a specific point.
Unlike other embedded monitors, HMON is designed to be integrated with the user code. HMON is supplied as a library file and several
configuration files. When debugging is no longer required, removing the monitor files and library from the code will leave the user’s code
operational.
The HMON embedded monitor code must be compiled with user software and downloaded to the CPU board, allowing the users’ code to
be debugged within HEW.
Due to the continuous process of improvements undertaken by Renesas the user is recommended to review the information provided on
the Renesas website at
www.renesas.com to check for the latest updates to the Compiler and Debugger manuals.
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 will 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
The HMON library is built to support 16Mbyte Advanced Mode only, for the H8S family.
10.4. Breakpoint Support
The device does not include a user break controller. No breakpoints can be located in ROM code. However, code located in RAM may
have multiple breakpoints limited only by the size of the On-Chip RAM. To debug with breakpoints in ROM you need to purchase the
E10A-USB on-chip debugger from your local disctributor.
10.5.Code located in RAM
Double clicking in the breakpoint column in the HEW code window sets the breakpoint. Breakpoints will remain unless they are do uble
clicked to remove them. (See the Tutorial Manual for more information on debugging with the HEW environment.)
10.6. HMON Code Size
HMON is built along with the user’s code. Certain elements of the HMON code must remain at a fixed location in memory. Table 10-1
details the HMON components and their size and location in memory. For more information, refer to the map file when building code.

10.7. Memory Map
The memory map shown in this section visually describes the locations of program code sections related to HMON, the FDT kernels and
the supporting code within the ROM/RAM memory areas of the microcontroller.
Figure 10.1: Memory Map
10.8. Baud Rate Setting
HMON is initially set to connect at 250000Baud. The value set in the baud rate register for the microcontroller must be altered if the user
wishes to change either the serial communication baud rate of the serial port or the operating frequency of the microcontroller. This value
is defined in the hmonserialconfiguser.h file, as SCI_CFG_BRR (see the Serial Port section for baud rate register setting values). The
project must be re-built and the resulting code downloaded to the microcontroller once the BRR value is changed. Please refer to the
HMON User Manual for further information.
32
10.9. Interrupt mask sections
HMON has an interrupt priority of ‘6’. The serial port has an interrupt priority of ‘7’. Modules using interrupts should be set to lower than this
value (5 or below), so that serial communications and debugging capability is maintained.
