1.2 Connecting the E10A-USB Emulator with the User System
Before connecting an E10A-USB emulator (hereafter referred to as the emulator) with the user
system, a connector must be installed in the user system so that a user system interface cable can
be connected. 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 H8S, H8SX Family 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.

Section 2 Specification of the Emulator’s Software
2.1 Differences between the H8SX/1725F, H8SX/1725SF, H8SX/1727SF,
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 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.
H8S, H8SX Family E10A-USB Emulator Section 2 Specification of the Emulator’s Software
R20UT2526EJ0300 Rev. 3.00 Page 10 of 30
Mar 14, 2013
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 power-
supply 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 Page 11 of 30
Mar 14, 2013
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.

18. 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.

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.

2.2.4 Sequential Break Function
The user program is halted when conditions of the Break condition for channels 2 to 4 are
matched. This function can be set in the [Emulation mode] drop-down list box of the
[Configuration] dialog box.
Table 2.6 Sequential Break condition Specification Items
Items Description
Sequential Break condition 2-1 Halts a program when a condition is satisfied in the order of
Break condition 2, 1.
Break condition 1, 2 must be set.
Sequential Break condition 3-2-1 Halts a program when a condition is satisfied in the order of
Break condition 3, 2, 1.
Break condition 1, 2, 3 must be set.
Sequential Break condition 4-3-2-1 Halts a program when a condition is satisfied in the order of
Break condition 4, 3, 2, 1.
Break condition 1, 2, 3, 4 must be set.
Note: When Sequential Break condition 4-3-2-1 is set, [Go To Cursor] is not available.
2.2.5 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.
2.2.6 Trace Function
The emulator uses the eight-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 branch-
source address, the mnemonic, and the operand.

(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 write-
disabled 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.

2.2.8 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.

2.2.9 Interface with Initialization, Write, and Erase Modules and Emulator Firmware
The initialization, write, and erase modules must be branched from the firmware when the
emulator is initiated and the external flash memory is written or read*.
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 2.8 (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.
