Notes: 1.
4
Do not connect anything to the N.C. pin of the H-UDI port connector.
2.
The processing of the /ASEMD pin differs depending on whether the emulator is used
or not. As the emulator does not control this pin, it must be controlled by a switch on
the board.
(1) When the emulator is used: /ASEMD = low (ASE mode)
(2) When the emulator is not used: /ASEMD = high (normal mode)
3.
The reset signal in the user system is input to the /RES pin of the SH7618. Connect
this signal to the H-UDI port connector as the output from the user system.
4.
When a network resistance is used for pull-up, it may be affected by a noise. Separate
TCK from other resistances.
5.
The pattern between the H-UDI connector and the MPU must be as short as possible.
Do not connect the signal lines to other components on the board.
6.
The resistance values shown in figure 1.2 are recommended.
7.
For the pin processing in cases where the emulator is not used, refer to the hardware
manual of the related device.

Software
2.1
Differences between the SH7618 and the Emulator
• 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 values of the actual SH7618 registers are undefined.

• The emulator uses the H-UDI; do not access the H-UDI.
• Low-Power States (Sleep and Standby)
For low-power consumption, the SH7618 has sleep and standby states.
The sleep and standby states are switched using the SLEEP instruction. When the emulator is
used, only the sleep state can be cleared with either the normal clearing function or with the [Stop]
button, and a break will occur.
Note: The memory must not be accessed or modified in sleep state.
7
• Reset Signals
The SH7618 reset signals are only valid during emulation started with clicking the GO or STEPtype button. If these signals are input from the user system in command input wait state, they are
not sent to the SH7618.
Note: Do not break the user program when the /RES and /WAIT signals are being low. A
TIMEOUT error will occur. If the /WAIT signal is fixed to low during break, a
TIMEOUT error will occur at memory access.
• Memory Access during User Program Execution
When a memory is accessed from the memory window, etc. during user program execution, the
user program is resumed after it has stopped in the E10A emulator to access the memory.
Therefore, realtime emulation cannot be performed.
The stopping time of the user program is as follows:
Environment:
®
Host computer: 650 MHz (Pentium III)
SH7618: 50 MHz
JTAG clock: 3.75 MHz
When a one-byte memory is read from the command-line window, the stopping time will be about
20 ms.
• Memory Access during User Program Break
The emulator can download the program for the flash memory area. Other memory write
operations are enabled for the RAM area. Therefore, an operation such as memory write or
BREAKPOINT should be set only for the RAM area.
• Cache Operation during User Program Break
When cache is enabled, the emulator accesses the memory by the following methods:
 At memory write: Writes through the cache, then writes to the memory.
 At memory read: Does not change the cache write mode that has been set.
Therefore, when memory read or write is performed during user program break, the cache state
will be changed.
• UBC
When [User] is specified in the [UBC mode] list box in the [Configuration] dialog box, the UBC
can be used in the user program.
8
Do not use the UBC in the user program as it is used by the E10A emulator when [EML] is
specified in the [UBC mode] list box in the [Configuration] dialog box.
• Loading Sessions
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be as follows:
When HS7618KCI01H is used: TCK = 4.125 MHz
When HS7618KCM01H is used: TCK = 3.75 MHz
• [IO] Window
 Display and modification
Do not change values of the user break controller because it is used by the emulator.
For each watchdog timer register, there are two registers to be separately used for write and
read operations.

Watchdog timer counter
• The watchdog timer operates only when the user program is executed. Do not change the value
of the frequency change register in the [IO] window or [Memory] window.
• The internal I/O registers can be accessed from the [IO] window. After the I/O-register file is
created, the MPU’s specification may be changed. If each I/O register in the I/O-register
definition file differs from addresses described in the hardware manual, change the I/O-register
definition file according to the description in the hardware manual. The I/O-register definition file
can be customized depending on its format. Note that, however, the E10A emulator does not
support the bit-field function.
• Verify
In the [IO] window, the verify function of the input value is disabled.
• Illegal Instructions
If illegal instructions are executed by STEP-type commands, the emulator cannot go to the next
program counter.

Break Condition Functions
In addition to BREAKPOINT functions, the emulator has Break Condition functions. Three types
of conditions can be set under Break Condition 1, 2, 3. Table 2.4 lists these conditions of Break
Condition.
Table 2.4 Types of Break Conditions
Break Condition Type
Description
Address bus condition (Address)
Breaks when the SH7618 address bus value or the program
counter value matches the specified value.
Data bus condition (Data)
Breaks when the SH7618 data bus value matches the
specified value. Byte, word, or longword can be specified as
the access data size.
Bus state condition
(Bus State)
There are two bus state condition settings:
Read/Write condition: Breaks when the SH7618 RD or
RDWR signal level matches the specified condition.
Bus state condition: Breaks when the operating state in an
SH7618 bus cycle matches the specified condition.
Types of buses that can be specified are listed below.
•
L-bus (CPU-ALL): Indicates an instruction fetch and data
access, including a hit to the cache memory.
•
L-bus (CPU-Data): Indicates a data access by the CPU,
including a hit to the cache memory.
•
I-bus (CPU.DMA): Indicates a CPU cycle when the
cache memory is not hit, and a data access by the
DMA.
Internal I/O break condition
Breaks when the SH7618 accesses the internal I/O.
Count
Breaks when the conditions set are satisfied the specified
number of times.
Note: When U-RAM is accessed from the P0 space, the I-bus must be selected, and when
accessed from the P2 space, the L-bus must be selected. When cache fill cycle is acquired,
the I-bus must be selected.

Internal Trace Function: This function is activated by selecting the [Internal trace] radio button
in the [Trace type] group box of the [Trace mode] page. This function traces and displays the
branch instructions. The branch source address and branch destination address for the four latest
branch instructions are displayed.
Notes: 1. If an interrupt is generated at the program execution start or end, including a step
execution, the emulator address may be acquired. In such a case, the following
message will be displayed. Ignore this address because it is not a user program address.
*** EML ***
2. If a completion-type exception occurs during exception branch acquisition, the next
address to the address in which an exception occurs is acquired.
3. Trace information cannot be acquired for the following branch instructions:
• The BF and BT instructions whose displacement value is 0
• Branch to H'A0000000 by reset
2.2.4
4.
When [User] is specified in the [UBC mode] list box in the [Configuration] window,
the internal trace is not acquired. In this case, exit the [Trace] window.
5.
The SH7618 E10A emulator does not display the source code on the [Trace] window.
Note on Using the JTAG Clock (TCK)
Set the JTAG clock (TCK) frequency to less than the frequency of the SH7618 peripheral module
clock (CKP).
2.2.5
Notes on Setting the [Breakpoint] Dialog Box
1. When an odd address is set, the next lowest even address is used.
2. A BREAKPOINT is accomplished by replacing instructions of the specified address.
Accordingly, it can be set only to the internal RAM area. However, a BREAKPOINT cannot
be set to the following addresses:
• An area other than CS0 to CS6 and the internal RAM
• An instruction in which Break Condition 2 is satisfied
• A slot instruction of a delayed branch instruction
3. During step execution, BREAKPOINTs are disabled.
4. Conditions set at Break Condition 2 are disabled when an instruction to which a
BREAKPOINT has been set is executed. Do not set a BREAKPOINT to an instruction in
which Break Condition 2 is satisfied.
5. When execution resumes from the address where a BREAKPOINT is specified, single-step
execution is performed at the address before execution resumes. Therefore, realtime operation
cannot be performed.
13
6. When a BREAKPOINT is set to the slot instruction of a delayed branch instruction, the PC
value becomes an illegal value. Accordingly, do not set a BREAKPOINT to the slot
instruction of a delayed branch instruction.
7. When a BREAKPOINT is set to the cacheable area, the cache block containing the
BREAKPOINT address is filled immediately before and after user program execution.
8. If an address of a BREAKPOINT cannot be correctly set in the ROM or flash memory area, a
mark z will be displayed in the [BP] area of the address on the [Editor] or [Disassembly]
window by refreshing the [Memory] window, etc. after Go execution. However, no break will
occur at this address. When the program halts with the break condition, the mark z disappears.
2.2.6
Notes on Setting the [Break Condition] Dialog Box and BREAKCONDITION_SET
Command
1. When [Go to cursor], [Step In], [Step Over], or [Step Out] is selected, the settings of Break
Condition 2 are disabled.
2.
Break Condition 2 is disabled when an instruction to which a BREAKPOINT has been set is
executed. Accordingly, do not set a BREAKPOINT to an instruction which satisfies Break
Condition 2.
3.
When a Break Condition is satisfied, emulation may stop after two or more instructions have
been executed.
4.
If a PC break address condition is set to the slot instruction after a delayed branch instruction,
user program execution cannot be terminated before the slot instruction execution; execution
stops before the branch destination instruction.
5.
Note that a break occurs with a break satisfaction condition by an instruction that has been
cancelled due to the generation of an exception.
6.
Use the sequential break or count break with the L-bus condition. If such break is used with
the I-bus condition, it will not operate correctly.
7.
A break will not occur with the execution counts specified on the execution of the multi-step
instruction.
