Chapter 2.Purpose This RSK is an evaluation tool for Renesas microcontrollers. Features include: • Renesas Microcontroller Programming. • User Code Debugging. • User Circuitry such as switches, LEDs and potentiometer(s). • Sample Application. • Sample peripheral device initialisation code. The CPU board contains all the circuitry required for microcontroller operation. This manual describes the technical details of the RSK hardware.
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.

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 which does not require E8. For more details please refer to H8SX/1663 Group Hardware Manual.
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. To program the user boot MAT, the device must be in Boot mode. Further details of programming the MATs are available in the H8SX/1663 Group hardware manual. When using the E8 debugger supplied with the RSK the mode transitions are executed automatically.
7.1.1.Boot mode The boot mode settings for this CPU board are shown in Table 7-2 below: MD2 MD1 MD0 LSI State after Reset FDT Settings End 0 1 0 Boot Mode A 0 Table 7-2: Mode pin settings The following picture shows these settings made in the E8Direct configuration dialog from HEW. Figure 7.
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/1664 supports 4 user modes. The memory map in all of these modes is 16Mbyte in size. The default user mode for CPU board supporting H8SX1664 is 7.
Chapter 8.Programming Methods All of the Flash ROM on the device (i.e. both MATs) 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.
The Flash Development Toolkit (FDT) is supplied to allow programs to be loaded directly on to the board using this method. Please select USB Direct interface while downloading the program. 8.4.Serial Port Programming This sequence is not required when debugging using the E8 supplied with the kit. The microcontroller must enter boot mode for programming, and the programming port must be connected to a host for program download.
Chapter 9.Headers 9.1.Microcontroller Headers Table 9-1 to Table 9-4 show the microcontroller pin headers and their corresponding microcontroller connections. The header pins connect directly to the microcontroller pin unless otherwise stated.

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.

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.
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).
