When the emulator system is initiated, it initializes the general registers and part of the control registers as shown in table 2.1. The initial value of the MCU is undefined. When the emulator is initiated from the workspace, a value to be entered is saved in a session. For the registers shown in table 2.1, values other than PC or CCR are not changed even if the CPU reset command is issued. If ER7 (SP) is changed as an odd value, it must be modified in the [Register] window. Table 2.1 Register Initial Values at Emulator Power-On Register Initial Value PC Reset vector value in the vector address table ER0 to ER6 H'0 ER7 (SP) H'10 CCR 1 for I mask, and others undefined EXR H'7F VBR H'0 SBR H'FFFFFF00 MACH H'0 MACL H'0 2. 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. 3. 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. R20UT2526EJ0300 Rev. 3.00 Mar 14, 2013 Page 9 of 30 H8S, H8SX Family E10A-USB Emulator Section 2 Specification of the Emulator's Software 4. The emulator communicates with the MCU by using the P34/TRST#, P37/TCK, P35/TMS, P63/TDO, and P36/TDI pins. These pins cannot be used. 5. The power consumed by the MCU can reach several mA. This is because the user power supply drives ICs to make the communication signal level match the user-system powersupply voltage. 6. Do not use an MCU that has been used for debugging. If the flash memory is reprogrammed many times, and the MCU is left for a few days, data may be lost due to retention problems. If the flash memory is reprogrammed many times, the data will not be erased. If an error message is displayed, exchange the MCU for a new one. 7. MCU Operating Mode Use the emulator in mode 3 (single-chip mode). 8. Sum Data Displayed in the Program Flash Mode Sum data, which is displayed in the `Program Flash' mode, is a value that data in the whole internal ROM areas has been added by bytes. 9. Note on Executing the User Program The set value is rewritten since the emulator uses flash memory and watchdog timer registers during programming (Go, Step In, Step Out, or Step Over) of the flash memory. 10. Note on Reprogramming the Flash Memory While the flash memory is reprogrammed during Go operation, actual reprogramming will not be performed if the flash memory is reprogrammed on the [Memory] window. Therefore, the contents will not be displayed correctly on the [Memory] window. 11. Value Set in the [System Clock] Dialog Box when Connecting the Emulator Input the frequency of the oscillator in use in the [System Clock] dialog box (this also applies when the MCU is multiplied by the PLL circuit). Figure 2.1 [System Clock] Dialog Box R20UT2526EJ0300 Rev. 3.00 Mar 14, 2013 Page 10 of 30 H8S, H8SX Family E10A-USB Emulator Section 2 Specification of the Emulator's Software 12. Emulation on Programming or Erasing the Internal Flash Memory A break cannot be generated while the program for programming or erasing the internal flash memory is being called. Note that the following processing also cannot be performed: Execution of the [STOP] button Auto-update of the watch function and use of the tool-chip watch function Memory operation during executing emulation 13. Note on Access to Memory When data-flash memory within the emulator is accessed etc. and the EEPROM read permission register has not been set, a FIFE (Flash Interface Error) interrupt will be generated when the user program is executed. 14.Note on FCU RAM Data If data in the FCU RAM are destroyed, subsequent flash-memory writing is not guaranteed. 15.Note on Flash Memory Synchronization Function The data cannot be read-out from flash memory after a transition to ROM/PE mode etc. If flash memory synchronization is used in this situation and data are read out from flash memory, correct data will not be displayed and data in flash memory may be overwritten. 16. [Run Program], GO_TILL Command [Run Program], GO_TILL command function is not available in this software. 17. Data Flash (EEPROM) Debugging the memory for data-flash area is available by using the setting described in section.2.2.8, Debugging in the External Flash Memory.

RAM Error Checking and Correction (ECC) Function When H8SX/1725SF or H8SX/1727SF is in use, the [ECC_OFF] checkbox is shown in the [Select Emulator mode] dialog box. When the RAM ECC function is disabled, select this checkbox. Figure 2.2 [Select Emulator mode] Dialog Box When the RAM ECC function is disabled, note the following restrictions. The start/stop function is not available. The PC break function (BREAKPOINT) cannot be specified for the internal RAM area.

Do not use an MCU that has been used for debugging. 2. If the flash memory is reprogrammed many times, and the emulator is left for a few days, data may be lost due to retention problems. 3. If the flash memory is reprogrammed many times, the data will not be erased. If an error message is displayed, exchange the MCU for a new one. 2.2.1 Emulator Driver Selection Table 2.2 shows drivers which can be selected in the [Driver Details] dialog box.

Table 2.3 lists the items that can be specified. Table 2.3 Hardware Break Condition Specification Items Items Description Address bus condition Breaks when the MCU address bus value matches the specified value. It is possible to select whether a break is generated before or after prefetched address execution. When [User mask] is selected, a value to be masked `*' can be set. For masked bits, the condition is satisfied for any values. Data bus condition Breaks when the MCU data bus value matches the specified value. Byte, word, or longword can be specified as the access data size. When [User mask] is selected, a value to be masked `*' can be set. For masked bits, the condition is satisfied for any values. Bus master condition Breaks when the values of DATA, DTC, and DMA cycles match the specified values. Read or write condition Breaks in the read or write cycle. Execution count condition The condition specified with Break condition 1 breaks after the execution count condition specified here has been satisfied.

R20UT2526EJ0300 Rev. 3.00 Mar 14, 2013 Page 15 of 30 H8S, H8SX Family E10A-USB Emulator Section 2 Specification of the Emulator's Software 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. When [Go To Cursor] is selected, the settings of Break condition channel 4 are disabled. 2.2.3 Notes on Setting the [Breakpoint] Dialog Box 1. When an odd address is set, the address is rounded down to an even address. 2. A BREAKPOINT is accomplished by replacing instructions. Accordingly, it can be set only to the flash memory or the RAM area. However, a BREAKPOINT cannot be set to the following addresses: 3. An area other than flash memory or RAM 4. An area occupied by the emulator program 5. During step execution, a BREAKPOINT is disabled. 6. A condition set at Break condition is disabled immediately after starting execution when an instruction at a BREAKPOINT is executed. A break does not occur even if a condition of Break condition is satisfied immediately after starting the execution. 7. When execution resumes from the breakpoint address after the program execution stops at the BREAKPOINT, single-step execution is performed at the address before execution resumes. Therefore, realtime operation cannot be performed. 8. Settings of BREAKPOINT and Break condition are invalid while the STEP OVER function is being used. 9. When a BREAKPOINT is set in the external flash memory area, the emulator executes the programs for initializing, programming, and erasing the flash memory (hereafter referred to as an initialization module, a write module, and an erase module, respectively*) to reprogram the external flash memory. Accordingly, the operation of the user program will differ when it is reexecuted after a break occurs. Note: Prepare initialization, write, and erase modules that are suitable for the external flash memory being used.

R20UT2526EJ0300 Rev. 3.00 Mar 14, 2013 Page 18 of 30 H8S, H8SX Family E10A-USB Emulator Section 2 Specification of the Emulator's Software (2) Limitations on the Conflict Conditions of Parallel Transfer Enabled Memory access by parallel transfer will be limited in the following conflict conditions. During software standby, a recovery with the [STOP] button will cause a malfunction of parallel transfer (a timout error will occur). A recovery should be operated by the user reset. If the memory access is performed by a parallel transfer when the user reset is input or watchdog timer (WDT) is reset, a malfunction of parallel transfer will occur (a writedisabled or indefinite value will be read). If the emulation mode is switched when the user reset is input or watchdog timer (WDT) is reset, a malfunction of parallel transfer will occur (a timout error will occur). (3) Access Size of Parallel Transfer During parallel transfer, when memory is accessed by the address except at the boundary of words or longwords, it is compensated to the boundary of access size. R20UT2526EJ0300 Rev. 3.00 Mar 14, 2013 Page 19 of 30 H8S, H8SX Family E10A-USB Emulator 2.2.8 Section 2 Specification of the Emulator's Software Debugging in the External Flash Memory This emulator supports debugging in the external flash memory, which is the function to allow downloading of programs to the external flash memory area. Settings for the external flash memory should be made in the [External Flash memory setting] dialog box opened at initiation of the emulator. To display the [External Flash memory setting] dialog box, check [Use External Flash memory setting] in the [Select Emulator mode] dialog box. Debugging function equivalent to that in the H8SX E10A-USB system becomes available in the external flash memory area by specifying the initialization, write, or erase module* and filling information on the external flash memory. Settings made in the [External Flash memory setting] dialog box are retained. Next time this dialog box is launched, the previous settings are displayed. Clicking the [Save] button saves the contents that have been set. The file to be saved (*.EFF: external flash memory data setting file) is loaded by clicking the [Browse...] button for [Select External Flash setting file]. When the file has been set, it is registered as the history (recent 10 files) in the combo box and selected to be loaded. Up to 1024 blocks can be specified for the external flash memory via the [External Flash memory setting] dialog box of the emulator. The maximum size allowed between the start address and the end address of the external flash memory is 16 Mbytes. Since this function forcibly changes the device settings in the emulator when the initialization, write, or erase module is called, the emulator operates differently with the contents of the user program. To verify the operation of the user program, disable the [Use External Flash memory] check box and activate the emulator. Notes: 1. Prepare initialization, write, and erase modules that are suitable for the external flash memory being used. 2. Debugging in the external flash memory is available for data flash (EEPROM) in this emulator. 3. Make settings in accord with the region of memory on the individual device. Table 2.8 lists the items contained in the [External Flash memory setting] dialog box.
