1.1 Real-Time RAM Monitor Function

This function allows you to inspect changes of memory contents without impairing the realtime capability of target program execution. The PC4701 emulator system contains a 1-Kbyte RAM monitor area (which cannot be divided into smaller areas). This debugger supports the real time RAM monitor function which allows you to reference the memory data without sacrificing real time performance during execution of the target program.

1.1.1 RAM Monitor Area

This debugger provides a 1KB of RAM monitor area, which can be placed at any continuous addresses.

1.1.2 Sampling Period

Sampling cycle means the display update interval. You can specify this function in any window which supports the RAM monitor. (The interval of 100 ms is set by default.) The actual sampling cycle may take longer time than the specified cycle depending on the operating environment. (Sampling cycle depends on the following environments.)
• Communication interface
• Number of the RAM Monitor windows displayed
• Size of the RAM Monitor window displayed
• Number of ASM watch points within the RAM monitor area of the ASM Watch window
• Number of C watch points within the RAM monitor area of the C Watch window

1.2 Break Functions

1.2.1 Software Breaks Function

Software Break breaks the target program before execution of the command at the specified address. This break point is called software breakpoint. The software breakpoint is set/reset in the Editor (Source) window or in the S/W Breakpoint Setting window. You can also disable/enable a software breakpoint temporarily. You can specify up to 64 software breakpoints. When specifying two or more software breakpoints, the breakpoint combination is based on the OR logic. (Arrival to any one of breakpoints breaks the target program.)
1.2.1.1 Setting of software breakpoint
The software breakpoint can be set by the following windows.
• Editor (Source) Window
• S/W Break Point Setting Window
You can double-click the mouse to set/reset the software breakpoint in the Editor (Source) window. You can also switch to temporarily disable/enable the software breakpoint in the S/W Breakpoint Setting window.
1.2.1.2 Area where software breakpoint can be set
The area which can be set for software breakpoint varies depending on the product. For the areas available for software breakpoint, see the following: "
12.1.2 Area where software breakpoint can be set"

1.2.2 Hardware Break

This function causes the target program to stop upon detecting a data read/write to memory, instruction execution, or the rising/falling edge of the input signal fed from an external trace cable. The contents of events that can be set vary with each target MCU.
The following designations are available as break events:
• Address designation
- Instruction fetch
- Memory access
- Bit access
• External trigger designation
• Interruption
The number of events that can be specified are six events of all. For the address designation method, instruction fetch and memory access allow the range designation and logical condition designation, in addition to the normal one-address designation. Moreover, instruction fetch allows you to specify the function name. Memory access allows you to specify the comparison data to read/write data related to the specified address in the same manner as when setting the H/W breakpoint. It also allows mask designation to the comparison data.
These break events can be combined as below:
• Trace when all of the valid events are established (AND condition)
• Trace when all of the valid events are established at the same time (simultaneous AND condition)
• Trace when one of the valid events is established (OR condition)
• Trace upon entering a break state during state transition (State Transition condition)
When transitional conditions set in an interstate pass are met, a state transition occurs, in which case the target program can be made to stop upon entering a break state. The conceptual diagram shown below depicts the relationship between state and pass.
State transition break allows you to select "specified task only" (or "other than specified task") as the break condition to meet the real time OS.

1.2.3 Protect Break

This function causes the target program to stop upon detecting a data write to the ROM area or an access to an unused area (read/write or instruction execution). Protect Break is a function to detect a write of data to the ROM area and an access (read, write, command execution) to an unused area and stop the target program.
1.2.3.1 Protect Attribute
You can specify the following attributes in byte.
• Access Disable
• Read Only
• R/W Enable
1.2.3.2 Access Protect Area
A protect area is a continuous 256-KB area starting from the 64KB boundary. Its start address is called protect base address. The protect base address immediately after starting the emulator is set to 0h.
The entire protect area is set to "R/W Enable" by default at start of the emulator.
1.2.3.3 Set Method of Protect Break
The two types of designation methods are provided:
• To fetch the memory attribute from the target program section information
• To specify the memory attribute of any area
5

1.3 Real-Time Trace Function

This function records a target program execution history. Up to 32K cycles of execution history can be recorded. This record allows inspecting the bus information, executed instructions, and source program execution path for each cycle. The real-time trace function records the execution history of the target program. The execution history is referred to in the tracing window. The execution history can be referred to in the following mode.
• BUS mode This mode allows you to inspect cycle-by-cycle bus information. The display content depends on the MCU and emulator system used. In addition to bus information, this mode allows disassemble, source line or data access information to be displayed in combination.
• Disassemble mode This mode allows you to inspect the executed instructions. In addition to disassemble information, this mode allows source line or data access information to be displayed in combination.
• Data access mode This mode allows you to inspect the data read/write cycles. In addition to data access information, this mode allows source line information to be displayed in combination.
• Source mode This mode allows you to inspect the program execution path in the source program.

1.3.1 Trace Area

The 32K cycles execution history can be referred to with this debugger. The trace area of the following 5 mode is being supported.
• Break 32K cycles before target program stops
• Before 32K cycles before trace point
• About 16K cycles either side of trace point
• After 32K cycles after trace point
• Full Until 32K cycles are written in the trace memory
"Break" is set by default. To refer the execution history before stopping the target program, use "Break" (designation of trace event is not required). To refer the execution history at any position, or to continue execution of the target program, specify the trace event and change the trance range.

1.3.2 Trace Condition Setting

The following designations are available as trace events:
• Address designation
- Instruction fetch
- Memory access
- Bit access
• External trigger designation (eight events)
• Interruption
The number of events that can be specified are six events of all. These break events can be combined as below:
• Trace when all of the valid events are established (AND condition)
• Trace when all of the valid events are established at the same time (And(same time) comdition)
• Trace when one of the valid events is established (OR condition)
• Trace upon entering a break state during state transition (State Transition condition)
You can select "specified task only" (or "other than specified task") as the trace condition to meet the real time OS.

1.3.3 Trace Data Write Condition

Trace data write conditions can be specified. You can specify the following write conditions:
• Write conditions unlimited (default)
• Cycles from the start event established to the end event established
• Only cycles where the start event is established
• Cycles from the start event established to the start event unestablished
• Other than cycles from the start event established to the end event established
• Other than cycles where the start event is established
• Other than cycles from the start event established to the start event unestablished

1.5 Coverage Function

Coverage Measurement is a function to record the addresses executed (accessed) by the target program (C0 coverage). After stopping execution of the target program, you can understand which addresses are not executed yet. By using the coverage measurement function in the test process, you can check for missing test items.

1.5.1 Coverage Measurement Area

The coverage measurement area is any continuous 256 KB area starting from the 64 KB boundary. The starting address is called coverage base address. The coverage base address immediately after starting the emulator is set to 0h.

3.3.2 LAN communication 1

Before the emulator can be connected in a LAN, the IP address, etc. must first be registered in the emulator. For the emulator in default settings, the utility "setip.exe" included with the debugger may be used to set the IP address, etc. in the emulator.
3.3.2.1 Setting of the LAN Interface using the SETIP.EXE
The utility "SETIP" included with this debugger may be used to set the IP address, etc. in the emulator while in default settings. SETIP detects the Emulator's in default settings that are connected to the same network. SETIP is stored in a location below the directory where this debugger is installed . The file name is "setip.exe".
To register the IP address in the emulator, follow the procedure described below.
1. Connect the emulator with LAN cable to the same network (same subnet) as the host computer
is connected.
2. Set the emulator's communication interface switch to the "LAN" position. Then turn on the
power to the emulator.
3. Start SETIP. When SETIP has started up, the dialog box shown below appears, choose the

port number, and default gateway IP address. When using the emulator on the same network's same subnet mask, the default gateway IP address may be omitted.
Use any 4-digit number to specify the port number. (Enter that number when starting the debugger.) For details about the contents of the IP address, subnet mask, and default gateway to be specified, contact your network administrator.
6. Click the Set button on the dialog box. The IP address, etc. that have been set are registered in
the emulator. When registered correctly, the dialog box shown below appears.
After checking the contents of the dialog box, click the OK button.
7. Temporarily turn off the power to the emulator and turn it back on again. The registered IP
address becomes effective after the emulator is powered up again.
ATTENTION
• If multiple Emulators in default settings are connected on the same network, only the first emulator detected is displayed.
• The emulators which have had an IP address already set cannot be detected by SETIP. In such a case, connect to the emulator through another communication interface and re-register the IP address from the Init dialog box that appears. For details on how to set IP addresses from the Init dialog box, see "
5.2.3Setting of the LAN Interface."

3.3.3 LAN communication 2

Please exexute registry setting program (Sack.exe) before starting the debugger. It is necessary for LAN communication with emulators to set the following registry.
OS
Key Data
Windows XP/2000 HKEY_LOCAL_MACHINE¥S
YSTEM¥CurrentControlSet¥ Services¥Tcpip¥Parameters¥ SackOpts
You can clear the registry with executing the program "UnSack.exe". The above programs are installed in the directory where this debugger is installed.
ATTENTION
Make sure Sack.exe and UnSack.exe is executed by one who is authorized as an Administrator. No one but the user who has the authority of an Administrator can install the device driver.
Note Windows XP/2000 TCP supports "Selective Acknowledgments (SACK)" as documented in RFC 2018. SACK gives higher performance in the network which have high bandwidth and long round-trip delays like satellite channels. SACK support is enabled by default in Windows XP/2000. It is necessary for LAN communication with emulators by Windows XP/2000 to disable SACK support. Setting the above registry can disable SACK support. Note that when you use the network which have high bandwidth and long round-trip delays like satellite channels, the performance with SACK support disabled is lower than with enabled.
