Access the following URL: http://www.hitachi.co.jp/Sicd/English/Products/micom/dev_env/tool/eml/e10a/e10atop.htm Rev. 2.0, 01/01, page 23 of 216 Rev. 2.0, 01/01, page 24 of 216 Section 3 Tutorial 3.1 Introduction The following describes the main functions of the HDI by using a tutorial program. The tutorial program is based on the C program that sorts ten random data items in ascending or descending order. The tutorial program performs the following actions: • The main function generates random data to be sorted. • The sort function sorts the generated random data in ascending order. • The change function then sorts the data in descending order. The file tutorial.c contains source code for the tutorial program. The file tutorial.abs is a compiled load module in the Dwarf2 format. Table 3.1 is a list of the parts of the tutorial program and an outline of their configuration on the hard disk. Table 3.1 Tutorial Program: Configuration and Parts Item Contents Workspace for HEW V1.2 [Installation directory]\tutorial\tutorial.hws Load module [Installation directory]\tutorial\tutorial\Debug\tutorial.abs Main program (source file) [Installation directory]\tutorial\tutorial\tutorial.c Stack information file [Installation directory]\tutorial\tutorial\Debug\tutorial.sni Use area 3 (CS3 space) as the operating environment. The MMU function is not used. Rev. 2.0, 01/01, page 25 of 216 Notes: 1. Operation of tutorial.abs is big endian. For little-endian operation, tutorial.abs must be recompiled. After recompilation, the addresses may differ from those given in this section. 2. This program was created by using Hitachi Embedded Workshop (hereafter referred to as HEW) V1.2. Older versions of HEW will not open the workspace included with the package, so create a new workspace in such situations. 3. This program was compiled without optimization for the SH2 CPU. If recompiled with different settings, the addresses may differ from those given in this section. 4. tutorial.abs is a load module in the Dwarf2 format. If a load module is recreated in the Sysrof format, the amount of information displayed on the HDI screen during the program’s execution will be reduced. 5. This section describes general usage examples for the emulator. For the specifications of particular products, refer to section 6 or the online help file.

Rev. 2.0, 01/01, page 28 of 216 3.4 Setting up the Emulator The clocks which are used for data communications must be set up on the emulator before the program is downloaded. • AUD clock A clock used in acquiring AUD traces. If its frequency is set too low, complete data may not be acquired during realtime tracing. If the frequency is set too high, the upper limit for the device’s AUD clock may be exceeded. The AUD clock is only needed for emulators that have an AUD trace function. • JTAG clock (TCK) A communication clock for downloading data to the emulator except for acquiring AUD trace. If its frequency is set too low, the speed of downloading will be lowered. If its frequency is set too high, the upper limit for the device’s TCK clock may be exceeded. For details of the limitations on both clocks, refer to section 6.5.4, Notes on Using the JTAG Clock (TCK) and AUD Clock (AUDCK). The following is a description of the procedure used to set the clocks.

Figure 3.57 [Trace] Window in the SH7751 E10A Emulator Rev. 2.0, 01/01, page 78 of 216 3.19.3 VP_MAP Translation The MCU, which has an MMU, translates internal addresses (virtual addresses) to actual memory addresses (physical addresses). Address translation is performed according to the address translation table (translation look-aside buffer: TLB) in the MCU. The MMU operates during command input wait state as well as during user program execution. When a command for memory access is executed while the MMU address translation function is enabled, the address translated by the MMU is accessed. If the specified address is not within the TLB, a TLB miss occurs, and the TLB must be updated by the user program. The emulator has address translation functions according to the VP_MAP tables. The VP_MAP tables are the address translation tables for the emulator created with the VPMAP_SET command. The following shows an example of how to use the VP_MAP tables. Example: 1. Create VP_MAP tables for translating virtual addresses H'10000 to H'10FFF to physical addresses H'4000000 to H'4000FFF and virtual addresses H'11000 to H'11FFF to physical addresses H'0 to H'FFF. >vs 10000 10FFF 4000000 (RET) >vs 11000 11FFF 0 (RET) >vd (RET) <VADDR_TOP> <VADDR_END> <PADDR_TOP> 00010000 00010FFF 04000000 00011000 00011FFF 00000000 DISABLE 2. Then, enable the VP_MAP tables. (When the tables are disabled, addresses are not translated.) >ve ;enable (RET) >vd (RET) <VADDR_TOP> <VADDR_END> 00010000 00010FFF 00011000 00011FFF ENABLE <PADDR_TOP> 04000000 00000000 Here, virtual addresses correspond to physical addresses as shown in figure 3.58. Rev. 2.0, 01/01, page 79 of 216 H'0 H'FFF H'10000 H'10FFF H'11000 H'11FFF H'12000 H'12FFF H'12000 H'12FFF H'4000000 H'4000FFF Virtual address Physical address Figure 3.58 Address Translation according to VP_MAP Tables How to translate addresses depends on the settings of the radio buttons of the memory area group in the [Configuration] dialog box. The following shows how to translate addresses in each setting state. • When the Normal radio button is selected: The VP_MAP table has a priority over the TLB. When the VP_MAP table is enabled and the specified address is within the VP_MAP table settings, the emulator translates the address according to the VP_MAP table. If the specified address is outside the VP_MAP table settings even when the VP_MAP table is enabled, or when the VP_MAP table is disabled, the emulator translates the address according to the MMU state. • When the Virtual radio button is selected: The address is translated according to the TLB. If the specified address is outside the TLB table settings, a TLB error will occur. • When the Physical radio button is selected: The address is not translated.

Top view Figure 6.3 Pin Arrangement of the Hitachi-UDI Port Connector (36 Pins) Notes: 1. Handling of the TCK, TMS, TDI, TDO, /TRST, and /ASEBRKAK pins depends on the use conditions of the Hitachi-UDI as follows: (a) When the user system is used by connecting the emulator, the TCK, TMS, TDI, TDO, /TRST, and /ASEBRKAK pins must be pulled up by a resistance of several kilo-ohms. The ASEMD0 pin must be grounded. The AUDATA3 to AUDATA0 and /AUDSYNC pins must be pulled up by a resistance of several kilo-ohms. The resistor of the AUDCK pin must be terminated (pulled up and pulled down by a resistance of several kiloohms). (b) When the user system is used independently without using the emulator and Hitachi-UDI, the TCK, TMS, TDI, TDO, /TRST, and /ASEBRKAK pins must be pulled up by a resistance of several kilo-ohms. The ASEMD0 pin also must be pulled up by a resistance of several kilo-ohms. The AUDCK, AUDATA3 to AUDATA0, and /AUDSYNC pins must be pulled up by a resistance of several kilo-ohms. Rev. 2.0, 01/01, page 187 of 216 2. The /RESET signal in the user side is input to the 193 pin of the SH7729 or SH7709A. Connect this pin to the Hitachi-UDI port connector as the output from the user system. 6.3 User System Interface Circuit The emulator is connected to the user system via the user interface cable.

The initial values of the actual SH7729 and SH7709A registers are undefined. Table 6.2 Register Initial Values at Emulator Power-On Register Emulator at Power-on R0 to R14 H'00000000 R15 (SP) H'A0000000 R0_BANK to R7_BANK H'00000000 PC H'A0000000 SR H'700000F0 GBR H'00000000 VBR H'00000000 MACH H'00000000 MACL H'00000000 PR H'00000000 SPC H'00000000 SSR H'000000F0 RS* H'00000000 RE* H'00000000 MOD* H'00000000 A0G, A1G* H'00 A0, A1* H'00000000 X0, X1* H'00000000 Y0, Y1* H'00000000 M0, M1* H'00000000 DSR* H'00 Note: These registers are not displayed when the SH7709A is selected. • The emulator uses the Hitachi-UDI; do not access the Hitachi-UDI. Rev. 2.0, 01/01, page 196 of 216 • Low-Power Mode (Sleep, Standby, and Module Standby) For low-power consumption, the SH7729 and SH7709A have sleep, standby, and module standby modes. The sleep and standby modes are switched using the SLEEP instruction. When the emulator is used, only the sleep mode can be cleared with either the normal clearing function or with the [Stop] button. Note that if a command has been entered in standby mode or module standby mode, no commands can be used from the emulator. The states cannot be canceled by the [Stop] button. Notes: 1. The memory must not be accessed or modified in sleep mode. 2. When the [Stop] button is clicked in sleep mode, a break does not occur immediately after executing the SLEEP instruction. The number of instructions to be proceeded differs according to the emulator environment or operating frequency of the chip. It is about 150 instructions when the Pentium III 500-MHz PC is used and the CPU clock is 25 MHz. • RESET Signals (/RESETP and /RESETM) The SH7729 and SH7709A RESET signals (/RESETP and /RESETM) are only valid during emulation started with clicking the GO or STEP-type button. If these signals are input from the user system in command input wait state, they are not sent to the SH7729 or SH7709A. Note: Do not break the user program when the /RESETP, /RESETM, /BREQ, and /WAIT signals are being low. A TIMEOUT error will occur. If the /BREQ and /WAIT signals are fixed to low during break, a TIMEOUT error will occur at memory access. • Direct Memory Access Controller (DMAC) The DMAC operates even when the emulator is used. When a data transfer request is generated, the DMAC executes DMA transfer. • Internal I/O Register In the emulator, the internal I/O can be accessed from the [I/O Registers] window. However, pay attention when accessing the SDMR register of the bus-state controller. Before accessing the SDMR register, specify addresses to be accessed in the I/O-register definition file (SH7729.IO or SH7709A.IO) and then activate the HDI. For the I/O-register definition file, refer to the Hitachi Debugging Interface User’s Manual. • Memory Access during Emulation 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: Rev. 2.0, 01/01, page 197 of 216 Environment: ® Host computer: 500 MHz (Pentium III) SH7729: 50 MHz (CPU clock) JTAG clock: 15 MHz When a one-byte memory is read from the command-line window, the stopping time will be about 47 ms. • Interrupt When the BLMSK bit in the ICR1 register is 1, the NMI interrupt is accepted during break and the program is executed from the NMI interrupt vector. If the program cannot return normally from the NMI interrupt routine or the value in the general-purpose register is not guaranteed, a communication timeout error will occur. • 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, BREAKPOINT, or user program download should be set only for the RAM area. When the memory area can be written by the MMU, do not perform memory write, BREAKPOINT, or downloading. • 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. Rev. 2.0, 01/01, page 198 of 216 6.5 Specific Functions for the SH7729 E10A Emulator The SH7729 E10A emulator does not support the following function: • Profiler function 6.5.1 Emulator Driver Selection Table 6.3 shows drivers which are selected in the [E10A Driver Details] dialog box. Table 6.3 Type Number and Driver Type Number Driver HS7729KCM01H E10A PC Card Driver 3 HS7729KCM02H E10A PC Card Driver 2 HS7729KCI01H E10A PCI Card Driver 3 HS7729KCI02H E10A PCI Card Driver 2 Rev. 2.0, 01/01, page 199 of 216 6.5.2 Break Condition Functions In addition to BREAKPOINT functions, the emulator has Break Condition functions. In the HDI, three types of conditions can be set under Break Condition 1, 2, 3. Table 6.4 lists these conditions of Break Condition. Table 6.4 Types of Break Conditions Break Condition Type Description Address bus condition (Address) Breaks when the SH7729 or SH7709A address bus value or the program counter value matches the specified value. Data bus condition (Data) Breaks when the SH7729 or SH7709A data bus value matches the specified value. Byte, word, or longword can be specified as the access data size and X-Bus or Y-Bus as the data type.* X-Bus or Y-Bus condition (Address and data) Breaks when the X-Bus or Y-Bus address bus or data bus matches the specified value.* ASID condition (ASID) Breaks when the SH7729 or SH7709A ASID value matches the specified condition. Bus state condition (Bus State) There are two bus state condition settings: Read/Write condition: Breaks when the SH7729 or SH7709A RD or RDWR signal level matches the specified condition. Bus state condition: Breaks when the operating state in an SH7729 or SH7709A bus cycle matches the specified condition. LDTLB instruction break condition Breaks when the SH7729 or SH7709A executes the LDTLB instruction. Internal I/O break condition Breaks when the SH7729 or SH7709A accesses the internal I/O. Count Breaks when the conditions set are satisfied the specified number of times. Note: When the SH7709A is selected, the data size for the X-Bus or Y-Bus access and X-Bus or Y-Bus condition (address and data) cannot be specified. Rev. 2.0, 01/01, page 200 of 216 Table 6.5 lists the combinations of conditions that can be set under Break Condition 1, 2, 3.

Table 6.6 Trace Functions Function Description Internal trace Branch instruction trace functions which are built into the device. This function displays the branch source and branch destination addresses and instruction words, and enables a realtime trace. AUD trace* Realtime trace This function is operational when the AUD pins are connected to the emulator. This function displays the branch source and branch destination addresses, and instruction words at the branch destination. When the next branch occurs while the trace information is output, the output of the information is stopped and the next trace information is output. The user program can be executed in realtime, but some trace information may be lost. • Trace continue function: When the trace buffer becomes full, this function overwrites the oldest trace information to store the latest trace information. • Trace stop function: After the trace buffer becomes full, the trace information is no longer acquired. (The user program is continuously executed.) Non realtime trace This function is operational when the AUD pins are connected to the emulator. This function displays the branch source and branch destination addresses, and instruction words at the branch destination. When the next branch occurs while the trace information is being output, the CPU stops operations until the information is output. The user program may not be executed in realtime. • Trace continue function: When the trace buffer becomes full, this function overwrites the oldest trace information to store the latest trace information. • Trace stop function: After the trace buffer becomes full, the trace information is no longer acquired. (The user program is continuously executed.) Note: When HS7729KCM01H and HS7729KCI01H are used, the AUD function cannot be used. Rev. 2.0, 01/01, page 202 of 216 Table 6.7 Type Number and AUD Function Type Number AUD Function HS7729KCM01H Not available HS7729KCM02H Available HS7729KCI01H Not available HS7729KCI02H Available Notes: 1. In the internal trace of the SH7729 and SH7709A, trace acquisition of the eight latest branch instructions is available. When the user program execution starts, the following one-branch trace is displayed: Branch source address: Previous user program execution end address Branch destination address: User program execution start address 2. In the internal trace of the SH7729 and SH7709A, the 4 most significant bits of address values are not acquired by trace. When the MMU is used, do not use the internal trace. Since the internal trace acquires only lower 28 bits, a TLB error may occur when the instruction code is displayed. When the emulator supports the AUD trace function, it is recommended to use the AUD trace. 3. For AUD trace, the difference from the previously output branch destination address is output as the branch destination address, and the difference from the previously output branch source address is output as the branch source address. If the upper 16 bits of the previously output branch destination/source address are the same, only the lower 17 bits are output. If the upper 24 bits are the same, only the lower 9 bits are output. If the upper 28 bits are the same, only the lower 5 bits are output. From this output difference, the emulator reproduces the 32-bit address and displays it in the [Trace] window. However, some 32-bit addresses cannot be displayed. In such cases, the difference from the previously displayed 32-bit address will be displayed. 4. When cache is ON (enabled), the CPU clock is 33 MHz, and the AUD clock is 30 MHz while Realtime trace is selected, trace information may not be completely acquired. Note that this phenomenon occurs at the following situation: 9 consecutive NOP instructions are followed by an infinite loop of the BRA instruction. 5. When the AUD trace function is used, the AUD clock (AUDCK) in the PCMCIA and PCI cards does not operate correctly at 60 MHz or more. Rev. 2.0, 01/01, page 203 of 216 6.5.4 Notes on Using the JTAG Clock (TCK) and AUD Clock (AUDCK) 1. When JTAG clock (TCK) is used, set the JTAG clock (TCK) frequency to lower than the frequency of half of the CPU clock. 2. When the AUD clock (AUDCK) is used, set the AUD clock (AUDCK) within the range between the quarter of the CPU clock and the CPU clock (60 MHz). 6.5.5 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 RAM area. However, a BREAKPOINT cannot be set to the following addresses: An area other than the CS0 to 6 areas and the internal RAM area An instruction in which Break Condition 2 is satisfied A slot instruction of a delayed branch instruction An area that can be only read by MMU 3. During step execution, a BREAKPOINT is disabled. 4. Condition 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 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. 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 the [Normal] option is selected in the [Memory area] group box in the [General] page of the [Configuration] dialog box, a breakpoint is set to a physical address or a virtual address according to the SH7729 or SH7709A MMU status during command input when the VPMAP_SET command setting is disabled. The ASID value of the SH7729 or SH7709A PTEH register during command input is used. When VPMAP_SET command setting is enabled, a breakpoint is set to a physical address into which address translation is made according to the VP_MAP table. However, for addresses out of the range of the VP_MAP table, the address to which a breakpoint is set depends on the SH7729 or SH7709A MMU status during command input. Even when the VP_MAP table is modified after breakpoint setting, the address translated when the breakpoint is set valid. Rev. 2.0, 01/01, page 204 of 216 8. When the [Physical] option is selected in the [Memory area] group box in the [General] page of the [Configuration] dialog box, a BREAKPOINT is set to a physical address. A BREAKPOINT is set after disabling the SH7729 or SH7709A MMU upon program execution. After setting, the MMU is returned to the original state. When a break occurs at the corresponding virtual address, the cause of termination displayed in the status bar and the [System Status] window is ILLEGAL INSTRUCTION, not BREAKPOINT. 9. When the [Virtual] option is selected in the [Memory area] group box in the [General] page of the [Configuration] dialog box, a BREAKPOINT is set to a virtual address. A BREAKPOINT is set after enabling the SH7729 or SH7709A MMU upon program execution. After setting, the MMU is returned to the original state. When an ASID value is specified, the breakpoint is set to the virtual address corresponding to the ASID value. The emulator sets the breakpoint after rewriting the ASID value to the specified value, and returns the ASID value to its original value after setting. When no ASID value is specified, the breakpoint is set to a virtual address corresponding to the ASID value at command input. 10. An address (physical address) to which a breakpoint is set is determined when the breakpoint is set. Accordingly, even if the VP_MAP table is modified after breakpoint setting, the breakpoint address remains unchanged. When a breakpoint is satisfied with the modified address in the VP_MAP table, the cause of termination displayed in the status bar and the [System Status] window is ILLEGAL INSTRUCTION, not BREAKPOINT. 11. 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. 12. Note on DSP repeat loop: A breakpoint is equal to a branch instruction. In some DSP repeat loops, branch instructions cannot be set. For these cases, do not set breakpoints. Refer to the hardware manual for details. 6.5.6 Notes on Setting the [Break Condition] Dialog Box 1. Break Condition 2 is disabled during step execution. 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 on DSP repeat loop: A breakpoint is equal to a branch instruction. In some DSP repeat loops, branch instructions cannot be set. For these cases, do not set breakpoints. Refer to the hardware manual for details. Rev. 2.0, 01/01, page 205 of 216 6.5.7 Notes on Setting the [Trace] Window 1. When MMU settings are modified or when a user program is changed after GO command completion before trace display, the displayed mnemonics or operand may not be correct. 2. When a completion-type exception occurs during exception branch acquisition, the next address to the address in which an exception occurs is acquired. 6.5.8 Notes on Setting the 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. Setting of 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 in which Break Condition 2 is satisfied. 3. 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 even when the PC option is specified in the <addrcycle> parameter; execution stops before the branch destination instruction. 4. When a Break Condition is satisfied, emulation may stop after two or more instructions have been executed. 5. Note on DSP repeat loop: A breakpoint is equal to a branch instruction. In some DSP repeat loops, branch instructions cannot be set. For these cases, do not set breakpoints. Refer to the hardware manual for details. Rev. 2.0, 01/01, page 206 of 216 6.5.9 Notes on Setting the UBC_MODE Command In the [Configuration] window, if [User] is set while the UBC_MODE command has been set, the STEP-type commands that use BREAK_CONDITION2 for implementation cannot be used. If these commands are used, the message box shown in figure 6.12 is displayed. Figure 6.12 [HDI] Message Box Note: Note the followings when the UBC is used in the user program: When the E10A emulator is connected: Always write 1 to bit 2 in the BRCR register. When the ASEMD0 pin is low without connecting the E10A emulator: Always write 1 to bit 2 in the BRCR register. When the ASEMD0 pin is high without connecting the E10A emulator: Always write 0 to bit 2 in the BRCR register. 6.5.10 Notes on HDI 1. Moving Source File Position after Creating Load Module When the source file is moved after creating the load module, the [Open] dialog box may be displayed to specify the source file during the debugging of the created load module. Select the corresponding source file and click the [Open] button. 2. Source-level Execution Source file Do not display source files that do not correspond to the load module in the program window. For a file having the same name as the source file that corresponds to the load module, addresses are displayed in the program window but operation in the window may not work properly. Step Even standard C libraries are executed. To return to a higher-level function, enter Step Out. In a for statement or a while statement, executing a single step does not move execution to the next line. To move to the next line, execute two steps. Rev. 2.0, 01/01, page 207 of 216 3. Operation During Accessing Files Do not perform other operations during saving in the [Load Program], [Verify Memory], [Save Memory], or [Trace] window because this will not allow correct saving to be performed. 4. Source Window at Program Change When a program being displayed in the source window is changed and the source file and load module are reloaded, close and reopen the source window once. If the window is not closed and reopened, the display may be incorrect. 5. Watch Local variables at optimization Depending on the generated object code, local variables in a C source file that is compiled with the optimization option enabled will not be displayed correctly. Check the generated object code by displaying the [Disassembly] window. If the allocation area of the specified local variable does not exist, displays as follows. Example: The variable name is asc. asc = ? - target error 2010 (xxxx) Variable name specification When a name other than a variable name, such as a symbol name or function name, is specified, no data is displayed. Example: The function name is main. main = Array display When array elements exceed 1000, elements from after 1000 will not be displayed. 6. Memory Load Function When [Load...] is selected from the [Memory] menu, the Memory Load function can be used although it takes time to download. It is recommended that the File Load function ([Load Program...] selected from the [File] menu) is used to load the S-type file. Note: The File Load function deletes the debugging information of the previously loaded program. When other load modules are loaded after the program to be debugged has been loaded, use the following sequence: When the program to be debugged is linked, save the debugging information in another file. Load the debugging information file after all the load modules have been loaded. Rev. 2.0, 01/01, page 208 of 216 7. Line Assembly Input radix Regardless of the Radix setting, the default for line assembly input is decimal. Specify H’ or 0x as the radix for a hexadecimal input. 8. Command Line Interface Batch file To display the message “Not currently available” while executing a batch file, enter the sleep command. Adjust the sleep time length which differs according to the operating environment. Example: To display “Not currently available” during memory_fill execution: sleep d’3000 memory_fill 0 ffff 0 Overwrite file In Command Line Interface, a file having the same name as the output file is overwritten without asking the user. File specification by commands The current directory may be altered by file specifications in commands. Absolute paths are recommended to be used to specify the files in a command file so that the current directory alteration is not affected. Example: FILE_LOAD C:\\HEW\\HDI5\\E10A\\7729\\TUTORIAL\\TUTORIAL \\DEBUG \\TUTORIAL.ABS 9. About Hitachi Debugging Interface User’s Manual This version of HDI does not support section 10, Selecting Functions, written in Hitachi Debugging Interface User’s Manual. 10. Note on Initiating HDI When the emulator is initiated by using another card emulator after it has been initiated by using the PCI card emulator, delete the [TARGET] line from the C:\windows\HDI.INI file. Rev. 2.0, 01/01, page 209 of 216 11. Usage with Another HDI Automatic load of session files Since the emulator cannot use another version of HDI, re-install this HDI whenever another version has been previously installed. If another version has been used, initiate this HDI with “Run” as follows without using the session files. <Directory path name in which HDI is installed>\hdi /n (RET) /n initiates the HDI without loading the recently used session files. If there is another session file in the different debug platform, the following error message is displayed: invalid target system: <recently used debug platform name> 12. [Select Function] Dialog Box This HDI does not support BREAKPOINT setting in the [Select Function] dialog box (described in section 10, Selecting Functions, in the Hitachi Debugging Interface User's Manual). 13. Memory Save During User Program Execution Do not execute memory save or verifying during user program execution. 14. [Performance Analysis] Window This HDI does not support the [Performance Analysis] window (described in section 13.9, Performance Analysis, in the Hitachi Debugging Interface User's Manual). 15. Load of Motorola S-type Files This HDI does not support Motorola S-type files with only the CR code (H'0D) at the end of each record. Load Motorola S-type files with the CR and LF codes (H'0D0A) at the end of each record. 16. [Memory] Window If the following memory contents are displayed, they will be incorrect. Word access from address 2n + 1 Longword access from address 4n + 1, 4n + 2, or 4n + 3 17. Scrolling Window During User Program Execution Do not scroll the [Memory] and [Disassembly] windows by dragging the scroll box during user program execution. This generates many memory reads causing the user program to stop execution until the memory reads have been completed. Rev. 2.0, 01/01, page 210 of 216 18. [I/O Registers] 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. Table 6.8 Watchdog Timer Register Register Name Usage Register WTCSR(W) Write Watchdog timer control/status register WTCNT(W) Write Watchdog timer counter WTCSR(R) Read Watchdog timer control/status register WTCNT(R) Read 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 [I/O Registers] window or [Memory] window. The value must be changed in the user program. The internal I/O registers can be accessed from the [I/O registers] window. However, note the following when accessing the SDMR register of the bus-state controller. Before accessing the SDMR register, specify addresses to be accessed in the I/O-register definition file (SH7729.IO and SH7709A.IO) and then activate the HDI. For details on I/O-register definition files, refer to the Hitachi Debugging Interface User’s Manual. Note that, however, the E10A emulator does not support the bit-field function described in the Hitachi Debugging Interface User’s Manual. Verify In the [I/O Registers] window, the verify function of the input value is disabled. 19. Note on [Registers] Window Operation During Program Execution Although a dialog box is displayed in which the register contents can be changed by doubleclicking the [Registers] window, do not change the register contents during program execution. The changed contents are not reflected. 20. Note on Radix in the [Register] Dialog Box The default input radix in the [Register] dialog box is hexadecimal irrespective of the Radix display. When a radix other than a hexadecimal is input, specify the prefix code such as B’. After the value has been input in the [Register] dialog box, the Radix setting is changed to hexadecimal. When the radix other than a hexadecimal is used as a default, reset the Radix display. Rev. 2.0, 01/01, page 211 of 216 21. BREAKPOINT Session file When the BREAKPOINT address set in the session file is H'0, the breakpoint will not be set. If the address set as the breakpoint is wrong, the error message is not output. The breakpoint is registered as DISABLE in the [Breakpoints] window. Breakpoint cancellation When the contents of the BREAKPOINT address is modified during user program execution, the following message is displayed when the user program stops. BREAKPOINT IS DELETED A=xxxxxxxx If the above message is displayed, cancel all BREAKPOINT settings with the [Delete All] or [Disable] button in the [Breakpoints] window. [Run program] dialog box If a disabled BREAKPOINT address is specified as a stop address in the [Run Program] dialog box, the disabled BREAKPOINT will become enabled after the user program has stopped. [Breakpoints] window During user program execution, it is impossible to jump from the breakpoint to the source or address line on the [Source] or [Disassembly] window by using [Go to Source] in the popup menu displayed on the [Breakpoints] window. 22. Number of BREAKPOINT and [Stop At] Settings in the [Run...] Menu The maximum number of BREAKPOINTs and [Stop At] settings allowed in the [Run...] menu is 255. Therefore, when 255 BREAKPOINTs are set, specification by [Stop At] in the [Run...] menu becomes invalid. Use the BREAKPOINTs and [Stop At] in the [Run...] menu with 255 or less total settings. 23. Note on RUN-TIME Display The execution time of the user program displayed in the [Status] window may not be accurate since the timer in the host computer is used. 24. Note on Displaying COMMUNICATION TIMEOUT ERROR If COMMUNICATION TIMEOUT ERROR is displayed, the emulator cannot communicate with the chip. Select [Initialize] from the [File] menu to initialize the emulator. 25. Note on Downloading Program In the [Load Program] dialog box, which is opened when [Load Program…] is selected, the verify function is invalid. After downloading the program, perform verify in the [Verify SRecord File with Memory] dialog box, which is opened when [Verify] is selected from the [Memory] menu. Rev. 2.0, 01/01, page 212 of 216 26. Note on [Fill Memory] Dialog Box The start and end addresses can be specified in the [Fill Memory] dialog box. When the start address value is larger than the end address value, note that the addresses are filled from the end to start. 27. Note on Using Old Version of Windows® 95 In using the old released version of Windows® 95 (such as 4.00.950a), if [Options…] is selected from the [Setup] menu, an application error occurs and the HDI abnormally exits. This is due to the old version of COMCTL32.DLL in the System directory of the Windows directory. Download the update program of COMCTL32.DLL from the Microsoft® homepage for installation, or update the version of Windows® 95. 28. Support of Double Float Format In the following memory operations, the double float format is not supported: [Fill Memory] dialog box [Search Memory] dialog box MEMORY_FILL command The [Format] specification in the [Copy Memory] dialog box is ignored. Memory is copied in a byte unit. Double float display at little endian operation 29. Note on Continuous Step Execution When the step is continuously executed by selecting [Step…] from the [Run] menu, do not use the BREAKPOINT because this will cause the HDI to abnormally operate. 30. Note on Using the [Run program] Dialog Box When [Run…] is selected from the [Run] menu to specify the stop address, there is the following note: When the breakpoint that has been set as Disable is specified as the stop address, note that the breakpoint becomes Enable when the user program stops. 31. Memory Test Function This product does not support the memory test function, which is used by selecting [test] from the [memory] menu. Rev. 2.0, 01/01, page 213 of 216 6.6 Limitations 1. The AUD and Hitachi-UDI pins are multiplexed as shown in table 6.9. Table 6.9 Multiplexed Functions Port Function 1 Function 2 E PTE0 input/output (port) TDO (Hitachi-UDI) E PTE7 input/output (port) /AUDSYNC output F PTF7 input (port) / PINT15 input (INTC) /TRST (AUD and Hitachi-UDI) F PTF6 input (port) / PINT14 input (INTC) TMS (Hitachi-UDI) F PTF5 input (port) / PINT13 input (INTC) TDI (Hitachi-UDI) F PTF4 input (port) / PINT12 input (INTC) TCK (Hitachi-UDI) G PTG6 input (port) /ASEMD0 (AUD and Hitachi-UDI) G PTG5 input (port) /ASEBRKAK (Hitachi-UDI) G PTG3 input (port)* AUDATA3 (AUD) G PTG2 input (port)* AUDATA2 (AUD) G PTG1 input (port)* AUDATA1 (AUD) G PTG0 input (port)* AUDATA0 (AUD) H PTH6 input (port)* AUDCK (AUD) Note: Note that function 1 cannot be used when the emulator is used. Function 1 can be used when the AUD pins are not connected to the emulator. 2. Since illegal breaks occur, the following break conditions must not be specified as break functions: DMA cycle I/O break If a break occurs during DMA transfer, it may be illegal. 3. If illegal instructions are executed by STEP-type commands, the emulator cannot go to the next program counter. 4. The SH7729 E10A emulator must be used after confirming that the TLB handler operates correctly. If the TLB handler does not operate correctly, the emulator is hanged up. In the E10A emulator, the MMU setting state is not changed during user program break. Therefore, when the MMU is on in the user program, it is still on after user program break. In SH7729 E10A emulator, note that the operation will be as follows if there is an access that generates the TLB exception during break: Rev. 2.0, 01/01, page 214 of 216 An area where a routine to set the TLB is prepared and address conversion is enabled in the TLB exception processing routine in the user program: • The display is illegal in the [Memory] and [Disassemble] windows. • Do not set the BREAKPOINT for the target area. The memory contents will be changed as H'0000. • A TIMEOUT error will occur if around the boundary of the logical address, which has been set in the TLB, is displayed in the window. An area where a routine to set the TLB is not prepared and address conversion is disabled in the TLB exception processing routine in the user program: • Restart the HDI after the E10A emulator has displayed a TIMEOUT error.
