When designing the user system, refer to an example of recommended connection between the connector and the MCU shown in this manual. Before designing the user system, be sure to read the E10A-USB emulator user’s manual and the hardware manual for related MCUs. Connect pins 8, 9, 10, 12, 13, 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.

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 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. 4. The emulator communicates with the MCU by using the on-chip emulator pins. The functions multiplexed with the on-chip emulator pins cannot be used. R20UT0271EJ0100 Rev. 1.00 May 13, 2011 Page 9 of 20 H8S, H8SX Family E10A-USB Emulator Section 2 Specifications of the Emulator’s Software 5. When the emulator is used, 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 power-supply voltage. 6. Do not use an MCU that has been used for debugging. If the flash memory is rewritten many times, and the MCU is left for a few days, data may be lost due to retention problems. If the flash memory is rewritten 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 The emulator supports mode 1, 2, 4, and 7 (on-chip emulation mode). 8. Programming Flash Memory during Debugging The flash memory is programmed in the following functions because they use breakpoints: • When executing [Go to cursor] • When stepping over the subroutine • When executing the subroutine at step-out operation 9. 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 ROM areas has been added by bytes. 10. 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. 11. Loading Sessions ⎯ Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading sessions. Thus the value of the JTAG clock (TCK) becomes the initial value at execution of start-up.

Figure 2.1 [System Clock] Dialog Box 13. 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 14.

R20UT0271EJ0100 Rev. 1.00 May 13, 2011 Page 13 of 20 H8S, H8SX Family E10A-USB Emulator Section 2 Specifications 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. 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. A BREAKPOINT cannot be set to the following addresses: • An area other than flash memory or RAM • An instruction in which Break Condition is satisfied 3. During step execution, a BREAKPOINT is disabled. 4. 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. 5. 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. 6. Settings of BREAKPOINT and Break Condition are invalid while the STEP OVER function is being used. 2.2.4 Note on Using the JTAG Clock (TCK) When the JTAG clock (TCK) is used, set the frequency to lower than that of the system clock. The value of the JTAG clock (TCK) becomes the initial TCK value that has been set at the starting up of the emulator, after [Reset CPU] or [Reset Go] is executed*. Note: The value of the JTAG clock (TCK) that has been set at the starting up of the emulator is appropriately calculated on the basis of the value entered in the [System clock] dialog box. R20UT0271EJ0100 Rev. 1.00 May 13, 2011 Page 14 of 20 H8S, H8SX Family E10A-USB Emulator 2.2.5 Section 2 Specifications of the Emulator’s Software Trace Function The emulator uses the branch-instruction trace function in the MCU, and acquires a trace by operating the user program in realtime. The branch-instruction trace function displays the eightchannel branch-source address, the mnemonic, and the operand. 2.2.6 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 H8S E10A-USB system becomes available in the external flash memory area by 1 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 2 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. Make settings accord with the region of memory on the individual device. Table 2.7 lists the items contained in the [External Flash memory setting] dialog box.

If not specified, select the setting of [recent setting data] (data previously changed) in the combo box. To make a new setting, select [initialize] and input data. 2 Use External Flash memory Enable or disable use of the external flash memory debugging function. Checked: Enabled Not checked: Disabled (default) 3 Erasing External Flash memory at Link up Select whether or not to erase the contents of the flash memory at initiation of the emulator. Checked: Erases the contents of the flash memory at initiation of the emulator. Not checked: Reads the contents of the flash memory at initiation of the emulator (default). 4 File name Specify the file of initialization, write, and erase modules. A program file must be specified for programming the flash memory. Prepare a file suitable for the flash memory being used. 5 Module offset address Specify the top address by an offset where the initialization, write, erasing modules are to be expanded. (Initial value is H’0). If not specified, disable offset. Checked: Enables offset. Not checked: Disables offset (default). (If the address exceeds H’FFFFFFFF, it will become H’0.) 6 Module top address Specify the top address where the initialization, write, and erase modules are to be expanded. (The 4-kbyte address areas starting from that address are saved by the emulator; it is possible to expand the initialization, write, and erase modules without affecting on the user program.) 7 Initialize module address Entry address of the initialization module The initialization module is used to set the device that is required for accessing the external flash memory. If not specified, disable entry. Checked: Enables entry. Not checked: Disables entry (default). 8 Erasing module address R20UT0271EJ0100 Rev. 1.00 May 13, 2011 Entry address of the erase module Page 17 of 20 H8S, H8SX Family E10A-USB Emulator Section 2 Specifications of the Emulator’s Software Table 2.7 Items in [External Flash memory setting] Dialog Box (cont) No. Item Description 9 Writing module address Entry address of the write module 10 Access size Select the unit of accesses for transfer of the programs. 8bits(Byte): Bytes 16bits(Word): Words 32bits(Long): Longwords 11 Top address Top address of the flash memory 12 End address End address of the flash memory* 13 Bus width Select the unit of accesses to the flash memory. 8bits(Byte): Bytes 16bits(Word): Words 32bits(Long): Longwords 14 Erasing time Waiting time for erasure (in seconds) (Specification of a decimal or hexadecimal value is recommended.) 15 Block count Number of blocks in the flash memory (Specification of a decimal or hexadecimal value is recommended.

Note: The modules are not called if the external flash memory data is not updated. To branch from the emulator firmware to the initialization, write, and erase modules, or to return from the initialization, write, and erase modules to the emulator firmware, the following conditions must be observed: • The size of each initialization, write, or erase module must be consecutive 4 Kbytes or less (including work areas and stack areas). • Save and return all the general register values and control register values before and after calling the initialization, write, or erase module. • Return the initialization, write, or erase module to the calling source after processing. • The initialization, write, and erase modules must be Motorola S-type files. • For the write module, write data ER1(L) to address ER0(L) and store the top address of flash memory ER2(L) then the result in ER0(L). • For the erase module, erase the block of address ER0(L) and store the top address of flash memory ER1(L) then the result in ER0(L). • Set the write size of the write module as described in No. 13 ‘Bus width’ in table 2.7 (byte, word, or longword). • The initialization module is used to set the device that is required for accessing the external flash memory. Store the result in ER0(L). The module interface must be as follows to correctly pass the information that is required for accessing flash memory.
