When designing the user system, refer to the connector and recommended circuits shown in this manual. Before designing the user system, be sure to read the E7 emulator user's manual and the hardware manual for related MCUs. Table 1.1 shows the recommended connector for the emulator. Table 1.1 Recommended Connector Type Number Manufacturer Specifications 2514-6002 3M Limited 14-pin straight type Connect pins 2, 4, 6, 10, 12, and 14 of the user system connector to GND firmly on the PCB. These pins are used as electrical GND and to monitor the connection of the user system connector. Note the pin assignments of the user system connector. User system interface cable Tab User system connector Pin 2 Pin 1 User system Figure 1.1 Connecting the User System Interface Cable to the User System 1 Notes: 2 1. The pin number assignments of the 14-pin connector differ from those of the E10A emulator; however, the physical location is the same. 2. Do not place any components within 3 mm of the connector. 3. When the emulator is used in the writer mode, connect the emulator similarly to the user system. Section 2 Pin Assignments of the E7 Connector Figure 2.1 shows the pin assignments of the connector.

Connect the emulator and MCU pins directly. In debugging without forced break control, change the mode with the HEW. Then, when the user logic is connected with the opencollector output buffer, the NMI# pin can be used in the user system (however, at power-on, the NMI# pin is used by the emulator).

Connect nothing with N.C. 6. The input voltage, Vcc, must be connected to the user system Vcc (power supply). The amount of voltage permitted to input to Vcc must be within the guaranteed range of the microcomputer. 7. Refer to the hardware manual for the recommended capacitance of the capacitor that is connected to the RES# pin. 8. Use of the internal oscillator circuit is available in the H8/38602RF. However, a resonator or an oscillator must be connected to OSC1 and OSC2 pins when the emulator is connected. 7 9. Figure 3.5 shows the interface circuit in the emulator. Use this figure as a reference when determining the pull-up resistance value.

Figure 3.5 Interface Circuit in the Emulator (Reference) 8 Section 4 Differences between the MCU (H8/38602RF) and the Emulator 1. When the emulator system is initiated, it initializes the general registers and part of the control registers as shown in table 4.1. Table 4.1 Register Initial Values at Emulator Power-On Register Initial Value PC Reset vector value in the vector address table ER0 to ER6 H'0000 ER7 (SP) H'FF80 CCR H'80 2. Low-Power Mode During a user program break, the CPU operating frequency is forced to a system clock () for high-speed operation. 3. RES# Signal The MCU signals are only valid during user program execution started with clicking the GO or STEP-type button. During a user program break, the RES# signal is not sent to the MCUs. Note: Do not start user program execution or access the memory while control input signal (RES#) is being low. A TIMEOUT error will occur. 4. System Control Register In the emulator, the internal I/O registers can be accessed from the [IO] window. However, be careful when accessing the system control register. The emulator saves the register value of the system control register at a break and returns the value when the user program is executed. Since this is done during a break, do not rewrite the system control register in the [IO] window. 5. Memory Access during Emulation If the memory contents are referenced or modified during emulation, realtime emulation cannot be performed because the user program is temporarily halted. 9 6. The emulator communicates with the MCUs by using the NMI#, RES#, and E7_2 to E7_0 pins. These pins cannot be used, however, the NMI# pin can be used by changing the setting of the [NMI signal] group box in the [Configuration] dialog box. 7. Sum Data Displayed in the Writing Flash memory Mode Sum data, which is displayed in the `Writing Flash memory' mode, is a value that data in the whole ROM areas has been added by byte. 8. Note on Executing the User Program The set value is rewritten since the emulator uses flash memory registers during programming (Go, Step In, Step Out, or Step Over) of the flash memory. 9. The power consumed by the MCU can reach several milliamperes. This is because the user power supply drives one HD74LVC125A to make the communication signal level match the user-system power-supply voltage. The power consumed rises little during user program execution since the emulator does not perform communication; it rises more during a break. 10. Program Area for the Emulator Do not access a part of areas in the flash memory or the internal RAM since the emulator program uses these areas. If the contents of the program area for the emulator are changed, the emulator will not operate normally. In this case, restart the emulator with the Download emulator firmware mode. Table 4.2 Program Area for the E7 Emulator MCU Name Program Area H8/38602RF Flash memory: H'4000 to H'4FFF Internal RAM: H'F780 to H'FB7F Vector, etc.: H'0002 to H'000F, H'0018 to H'0019, H'4FF8 to H'4FF9 11. The emulator uses a two-word stack pointer for values stored on a user program break. Therefore, the stack area must accept two-word addresses. 12. Do not use an MCU that has been used for debugging. If the flash memory is rewritten many times, data may be lost due to retention problems after the emulator has been left for a few days and the data will be erased. If an error message is displayed, exchange the MCU for a new one. 10 13. Forced Break Function When the NMI# signal is used for a forced break in the emulator, the vector address of NMI# is rewritten by the emulator program. An error will occur if a file in the host computer and the flash memory contents are verified. Do not use the flash memory contents as the ROM data for the mask ROM after it has been saved. 14. Setting the Usage of the NMI# Signal In the [Configuration] dialog box, when the NMI# signal is changed as it is used in the user program, the vector address of NMI# is not recovered. Reload the user program. 15. Initializing the Internal I/O Register with the Reset_CPU Function Be sure to initialize the following internal I/O registers by the user program since they are not initialized by selecting [Debug] - [Reset CPU] or using the RESET command: SYSCR1, SYSCR2, IEGR, IENR1, and IRR1 16. Step Execution of the SLEEP Instruction When the interrupt mask bit (I) in the condition code register (CCR) is 1, do not perform step execution of the SLEEP instruction. If the step execution is performed and not finished correctly, restart the emulator. 17. Use of the internal oscillator circuit is available in the H8/38602RF. However, a resonator or an oscillator must be connected to OSC1 and OSC2 pins when the emulator is connected. 18. Processing at Emulator Activation When the emulator is activated, the watchdog timer is not active; the operation of the emulator differs from that of the actual MCU. 19. Hardware Break Functions * In the H8/38602RF E7 emulator, conditions of Break Condition 1,2 can be set. Table 4.3 lists the items that can be specified. 20. Restriction on Software Write Enable (SWE) Bit If the SWE bit is set to 1 during execution of the user program, a communication timeout error will occur. Do not set this bit to 1. 11 Table 4.3 Hardware Break Condition Specification Items Items Description Address bus condition Breaks when the MCU address bus value matches the specified value. Data bus condition Breaks when the MCU data bus value matches the specified value. High or low byte or word can be specified as the access data size. Read or write condition Breaks in the read or write cycle. Table 4.4 lists the combinations of conditions that can be set in the [Break condition] dialog box. Table 4.4 Conditions Set in [Break condition] Dialog Box Condition Dialog Box Address Bus Condition O O [Break condition 1] [Break condition 2] Data Condition O X Read or Write Condition O X Note: O: Can be set by checking the radio button in the dialog box. Table 4.5 lists the combinations of conditions that can be set by the BREAKCONDITION_ SET command. Table 4.5 Conditions Set by BREAKCONDITION_SET Command Condition Channel Break condition 1 Break condition 2 Address Bus Condition (<addropt> option) O O Data Condition (<dataopt> option) O X Note: O: Can be set by the BREAKCONDITION_SET command. 12 Read or Write Condition (<r/wopt> option) O X * Notes on Setting the Break Condition 1. When [Step In], [Step Over], or [Step Out] is selected, the settings of Break Condition are disabled. 2. The settings of Break Condition are disabled when an instruction to which a BREAKPOINT has been set is executed. 3. When step over function is used, the settings of BREAKPOINT and Break Condition are disabled. 4. Do not satisfy Break Condition 2 and another break source (BREAKPOINT or Break Condition 1) simultaneously. A break will occur with an illegal value. 13 14 Tiny/Super Low Power E7 Emulator Additional Document for User's Manual Notes on Connecting the H8/38602RF Publication Date: Rev.1.00, March 24, 2004 Rev.3.00, September 12, 2006 Published by: Sales Strategic Planning Div.
