Graphical User Interface intended to ease the development and debugging of applications written in C/C++ programming language and assembly language for Hitachi microcomputers. Its aim is to provide a powerful yet intuitive way of accessing, observing and modifying the debugging platform in which the application is running. Key Features * Windows GUI for debugging (R) * Intuitive interface * On-line help * Common "Look & Feel" Note: The HDI does not run on Windows version 3.1. The simulator/debugger provides simulation functions for H8S and H8/300 series microcomputers (H8/300, H8/300L, H8/300H, H8S/2600, and H8S/2000 series) and provides debugging functions for programs written in C, C++, or assembly language. Therefore, the simulator/debugger promotes efficient debugging of programs. When used with the following software, the simulator/debugger reduces the time required for software development. * Hitachi Embedded Workshop (HEW) * H8S and H8/300 series C/C++ compiler * H8S and H8/300 series cross assembler * Optimizing linkage editor (R) 1.1 Features * Since the simulator/debugger runs on a host computer, software debugging can start without using an actual user system, thus reducing overall system development time. * The simulator/debugger performs a simulation to calculate the number of instruction execution cycles for a program, thus enabling performance evaluation without using an actual user system. * The simulator/debugger offers the following features and functions that enable efficient program testing and debugging. The ability to handle all of the H8S and H8/300 series CPUs Functions to trace instructions or subroutines Rev. 6.0, 09/00, page 1 of 187 Functions to stop or continue execution when an error occurs during user program execution Profile data acquisition and function-unit performance measurement A comprehensive set of break functions Functions to set or edit memory maps Functions to display function call history * The breakpoint, memory map, performance, and trace can be set through the dialog box (R) under Windows . Environments corresponding to each memory map of the H8S and H8/300 microcomputers can be set through the dialog box. 1.2 Target User Program Load modules in ELF/DWARF format and S-type format can be debugged with the simulator/debugger. These load modules are called user programs in this manual. Figure 1.1 shows the creation of target user programs to be debugged. Rev. 6.0, 09/00, page 2 of 187 Assembly source program C source program C++ source program H8S and H8/300 series cross assembler H8S and H8/300 series C/C++ compiler Instance information file Prelinker Object load module Library file Optimizing linkage editor Load module (ELF/S type) Stack information/ profile information H8S and H8/300 series simulator/debugger Figure 1.1 Creation of Target User Programs Rev. 6.0, 09/00, page 3 of 187 1.3 Simulation Range The simulator/debugger supports the following H8S and H8/300 series microcomputer functions: * All CPU instructions * Exception processing * Registers * All address areas The simulator/debugger does not support the following H8S and H8/300 series MCU functions. Programs that use these functions must be debugged with the H8S and H8/300 series emulator. * Dual port RAM * Timers * Pulse width modulator (PWM) * Serial communication interface (SCI) * A/D converter * I/O ports * Interrupt controller Rev. 6.0, 09/00, page 4 of 187 Section 2 System Overview HDI is a modular software system, utilizing self-contained modules for specific tasks. These modules are linked to a general purpose Graphical User Interface, which provides a common look & feel independent of the particular modules with which the system is configured. 2.1 User Interface (R) The HDI Graphical User Interface is a Windows application that presents the debugging (R) platform to you and allows you to set up and modify the system. Refer to a standard Windows (R) user manual for details on how to operate within a Windows application. 2.2 Data Entry When entering numbers in any dialog box or field you can always enter an expression instead of a simple number. This expression can contain symbols and can use the operators in the C/C++ programming languages. Use of C/C++ programming language features such as arrays and structures is only available if an object DLL that supports C/C++ programming language debugging is in use. In some dialogs, where there is a control expecting an end address, it is possible to enter a range by prefixing the value with a + sign. This will set the actual end address to be equal to the start address plus the entered the value. 2.2.1 Operators The C/C++ programming language operators are available: +, -, *, /, &, |, ^, ~, !, >>, <<, %, (, ), <, >, <=, >=, ==, !=, &&, || 2.2.2 Data Formats Unprefixed data values will be taken as being in the default radix set by the [Setup->Radix] menu option. The exception is count field which use decimal values by default (independent of the current default system radix). Symbols may be used by name and ASCII character strings can be entered if surrounded by single quote characters, e.g. `demo'. The following prefixes can be used to identify radices: O' B' Octal Binary Rev. 6.0, 09/00, page 5 of 187 D' H' 0x Decimal Hexadecimal Hexadecimal The contents of a register may be used by specifying the register name, prefixed by the # character, e.g.: #R1, #ER3, #R4L 2.2.3 Precision All mathematics in expression evaluation is done using 32 bits (signed). Any values exceeding 32 bits are truncated. 2.2.4 Expression Examples Buffer_start + 0x1000 #R1 | B'10001101 ((pointer + (2 * increment_size)) & H'FFFF0000) >> D'15 !(flag ^ #ER4) 2.2.5 Symbol Format You can specify and reference symbols in the same format as in C/C++ programming language. Cast operators may be used together with symbols, and you can reference data after its type has been converted. Note the following limitations. * Pointers can be specified up to four levels. * Arrays can be specified up to three dimensions. * No typedef name can be used. 2.2.6 Symbol Examples : Specifies direct reference of a member (C/C++) : Specifies indirect reference of a member (C/C++) : Specifies reference of a member with class (C++) : Specifies a pointer (C/C++) : Specifies an array (C/C++) : Specifies reference of a pointer to member (C++) : Specifies reference of a global variable (C/C++) : Specifies a member function (C++) : Specifies cast operation (C/C++) Object.value p_Object->value Class::value *value array[0] Object.*value ::g_value Class::function(short) (struct STR) *value Rev. 6.0, 09/00, page 6 of 187 2.3 Help (R) HDI has a standard Windows context sensitive help system. This provides on-line information about using the debugging system. Help can be invoked by pressing the F1 key or via the Help menu. Additionally, some windows and dialog boxes have a dedicated help button to launch the help file at the appropriate content. 2.3.1 Context Sensitive Help To get help on a specific item in the HDI help cursor can be used. To enable the help cursor, press SHIFT+F1 or click the button on tool bar. Your cursor then changes to include a question mark. You can then click on the item for which you require help and the help system will be opened at the appropriate content. Rev. 6.0, 09/00, page 7 of 187 Rev. 6.0, 09/00, page 8 of 187 Section 3 Simulator/Debugger Functions This section describes the H8S and H8/300 series simulator/debugger functions. 3.1 Simulator/Debugger Platforms and CPU Types Each simulator/debugger platform corresponds to a specific type of CPU as listed in table 3.1. Select a correct platform from the Select Session dialog box. Table 3.1 Simulator/Debugger Platforms and CPU Types CPU Type H8/300 H8/300L H8/300H advanced mode H8/300H normal mode H8S/2600 advanced mode H8S/2600 normal mode H8S/2000 advanced mode H8S/2000 normal mode Simulator/Debugger Platform H8/300 simulator H8/300L simulator H8/300HA simulator H8/300HN simulator H8S/2600A simulator H8S/2600N simulator H8S/2000A simulator H8S/2000N simulator 3.2 3.2.1 Simulator/Debugger Memory Management Memory Map Specification A memory map is specified to calculate the number of memory access cycles during simulation. The simulator/debugger supports the memory types shown in table 3.2. Table 3.2 Memory Types User Program Execution Enabled Enabled Enabled Disabled Enabled Memory Type Internal ROM Internal RAM External memory Internal I/O EEPROM A memory map can be specified in the System Configuration dialog box to calculate the number of memory access cycles during simulation. Rev. 6.0, 09/00, page 9 of 187 The following items can be specified: * Memory type * Start and end addresses of the memory area * Number of memory access cycles * Memory data bus width The memory types that can be specified depend on the CPU. For details, refer to section 5.18, System Configuration Dialog Box. The user program can be executed in all areas except for the internal I/O area. 3.2.2 Memory Resource Specification A memory resource must be specified to load and execute a user program. The memory resource, including the following items, can be specified in the System Memory Resource Modify dialog box. * Start address * End address * Access type The access type can be read/write, read-only, or write-only. Since an error occurs if the user program attempts an illegal access (for example, trying to write to a read-only memory), such an illegal access in the user program can be easily detected. However, unlike the other memory areas, a read-only EEPROM can be written to with the EEPMOV instruction and a writable EEPROM can be written to only with the EEPMOV instruction. 3.3 Instruction Execution Reset Processing The simulator/debugger resets the instruction execution count and instruction execution cycles when: * The program counter (PC) is modified after the instruction simulation stops and before it restarts. * The RUN command to which the execution start address has been specified is executed. * Initialization is performed, or a program is loaded. Rev. 6.0, 09/00, page 10 of 187 3.4 Exception Processing The simulator/debugger detects the exceptions corresponding to TRAPA instructions (only for the H8/300H and H8S series) and traces (only for the H8S series) and then simulates exception processing. The simulator/debugger simulates exception processing with the following procedures. 1. Detects an exception during instruction execution. 2. Saves the PC and CCR register in the stack area. If the validity bit in EXR is set to 1, the simulator/debugger also saves the EXR register. If an error occurs while saving registers, the simulator/debugger stops exception processing, displays that an exception processing error has occurred, and enters the command input wait state. 3. Sets the I bit in the CCR register as 1. 4. Reads the start address from the vector address corresponding to the vector number. If an error occurs while reading the address, the simulator/debugger stops exception processing, displays that an exception processing error has occurred, and enters the command input wait state. 5. Starts instruction execution from the start address. If the start address is 0, the simulator/debugger stops exception processing, displays that an exception processing error has occurred, and enters the command input wait state. 3.5 Features Specific to H8S/2600 CPU MAC Instruction: The H8S/2600 CPU performs multiply and accumulate operation (MAC instruction). Either saturation or non-saturation multiply and accumulate operation can be executed depending on the state of bit 7 (the MACS bit) in the SYSCR register in the internal I/O: MACS bit = 0: Non-saturation operation MACS bit = 1: Saturation operation EXR Register: The H8S/2600 CPU has the EXR register, which can be enabled or disabled by the state of bit 5 (the EXR bit) in the SYSCR register in the internal I/O: EXR bit = 0: EXR disabled EXR bit = 1: EXR enabled The SYSCR register address can be specified using [SYSCR Address] in the System Configuration dialog box. Note: The SYSCR register address must be within the internal I/O; otherwise the simulator/debugger assumes the MACS bit as 0 (non-saturation operation) and EXR bit as 0 (EXR disabled). Rev. 6.0, 09/00, page 11 of 187 For details, refer to section 5.18, System Configuration Dialog Box, section 5.22, Control Registers Window, and section 5.23, SYSCR Dialog Box. 3.6 Control Registers For the H8S/2600 series, the simulator/debugger supports the system control register (SYSCR) as a memory-mapped control register. Therefore, a user program using multiply and accumulate operation and EXR access can be simulated and debugged. The SYSCR address can be specified using [SYSCR Address] in the System Configuration dialog box. To modify or display the control register value, use the Control Registers window and the SYSCR dialog box. For details, refer to section 5.18, System Configuration Dialog Box, section 5.22, Control Registers Window, and section 5.23, SYSCR Dialog Box. 3.7 Trace The simulator/debugger writes the results of each instruction execution into the trace buffer. The trace buffer can hold the results for up to 1024 instruction executions. The conditions for the trace information acquisition can be specified in the Trace Acquisition dialog box. Click the right mouse button in the Trace window and choose [Acquisition] from the popup menu to display the Trace Acquisition dialog box. The acquired trace information is displayed in the Trace window. The trace information displayed in the Trace window is as follows. * Total number of instruction execution cycles * Instruction address * CCR * Multiplier internal flag (only for the H8S/2600 series) * Instruction mnemonic * Data access information (destination and accessed data) * C/C++ or assembly-language source programs The trace information can be searched. The search conditions can be specified in the Trace Search dialog box. Click the right mouse button in the Trace window and choose [Find] from the popup menu to display the Trace Search dialog box. For details, refer to section 5.14, Trace Window through section 5.16, Trace Search Dialog Box. Rev. 6.0, 09/00, page 12 of 187 3.8 Standard I/O and File I/O Processing The simulator/debugger provides the Simulated I/O window to enable the standard I/O and file I/O processing listed in table 3.3 to be executed by the user program. When the I/O processing is executed, the Simulated I/O window must be open. Table 3.3 lists the I/O processing functions supported by the simulator/debugger. Each function has three types of function codes: those for the 16-bit address, for the 24-bit address, and for the 32-bit address. Select one according to the target CPU.

Set the address specialized for I/O processing in the [System Call Address], select [Enable] and execute the program. 2. When detecting a subroutine call instruction (BSR or JSR), that is, a system call to the specialized address during user program execution, the simulator/debugger performs I/O processing by using the R0 and R1 values (H8/300 and H8/300L series) or the ER1 value (H8/300H and H8S series) as the parameters. Therefore, before issuing a system call, set as follows in the user program: Rev. 6.0, 09/00, page 13 of 187 * Set the function code (table 3.3) to the R0 register MSB 1 byte H'01 1 byte Function code LSB * Set the parameter block address to the R1 register (for the parameter block, refer to each function description) MSB Parameter block address LSB * Reserve the parameter block and input/output buffer areas Each parameter of the parameter block must be accessed in the parameter size. After the I/O processing, the simulator/debugger resumes simulation from the instruction that follows the system call instruction. Each I/O function is described in the following format: (1) (2) (3) (4) Parameter Block (5) Parameters (6) (1) Number corresponding to table 3.3 (2) Function name (3) Function code (4) I/O overview (5) I/O parameter block (6) I/O parameters Rev. 6.0, 09/00, page 14 of 187 1 GETC H'01, H'11, H'21 Inputs one byte from the standard input device Parameter Block * Function code: H'01 (for the 16-bit address) One byte +0 One byte Input buffer start address * Function code: H'11 (for the 24-bit address) or H'21 (for the 32-bit address) One byte +0 Input buffer start address +2 One byte Parameters * Input buffer start address (input) Start address of the buffer to which the input data is written to. 2 PUTC H'02, H'12, H'22 Outputs one byte to the standard output device Parameter Block * Function code: H'02 (for the 16-bit address) One byte +0 One byte Output buffer start address * Function code: H'12 (for the 24-bit address) or H'22 (for the 32-bit address) One byte +0 Output buffer start address +2 One byte Parameters * Output buffer start address (input) Start address of the buffer in which the output data is stored.

However, the calculated number of execution cycles may differ from that for the actual user system because the number of instruction execution cycles for some instructions and processing are treated as follows. * MOVFPE and MOVTPE instructions The number of data transfer cycles of an E-clock-synchronous instruction ranges from 9 to 16. The simulator/debugger calculates the total number of instruction execution cycles by assuming the number of data transfer cycles as 11, and adding the number of operand access cycles to it. The number of operand access cycles is determined by the memory data bus width and the number of memory access cycles. * EEPMOV instruction The number of execution cycles for an EEPROM write instruction is the sum of the instruction read cycles and data transfer cycles. * SLEEP instruction The simulator/debugger does not count the number of execution cycles of the SLEEP instruction because the instruction is usually used to stop program execution. * Standard I/O and file I/O processing The simulator/debugger does not count the number of execution cycles of standard I/O and file I/O processing because the processing is specific to the simulator/debugger. Here, standard I/O and file I/O processing begins when execution has jumped, due to the BSR or JSR instruction, to an address specified in [System Call Address] and ends when execution has returned to the calling address. 3.10 Break Conditions The simulator/debugger provides the following conditions for interrupting the simulation of a user program during execution. * Break due to the satisfaction of a break command condition * Break due to the detection of an error during execution of the user program * Break due to a trace buffer overflow * Break due to execution of the SLEEP instruction * Break due to the [STOP] button Rev. 6.0, 09/00, page 25 of 187 3.10.1 Break Due to the Satisfaction of a Break Command Condition There are five break commands as follows: * BREAKPOINT: * BREAK_ACCESS: * BREAK_DATA: * BREAK_REGISTER: * BREAK_SEQUENCE: Break based on the address of the instruction executed Break based on access to a range of memory Break based on the value of data written to memory Break based on the value of data written to a register Break based on a specified execution sequence When a break condition is satisfied during user program execution, the instruction at the breakpoint may or may not be executed before a break depending on the type of break, as listed in table 3.4. Table 3.4 Command BREAKPOINT BREAK_ACCESS BREAK_DATA BREAK_REGISTER BREAK_SEQUENCE Processing When a Break Condition is Satisfied Instruction When a Break Condition is Satisfied Not executed Executed Executed Executed Not executed For BREAKPOINT and BREAK_SEQUENCE, if a breakpoint is specified at an address other than the beginning of the instruction, the break condition will not be detected. When a break condition is satisfied during user program execution, a break condition satisfaction message is displayed on the status bar and execution stops. 3.10.2 Break Due to the Detection of an Error During Execution of the User Program The simulator/debugger detects simulation errors, that is, program errors that cannot be detected by the CPU exception generation functions. The System Configuration dialog box specifies whether to stop or continue the simulation when such an error occurs. Table 3.5 lists the error messages, error causes, and the action of the simulator/debugger in the continuation mode. Rev. 6.0, 09/00, page 26 of 187 Table 3.5 Simulation Errors Error Cause A PC value was an odd number. An instruction was fetched from the internal I/O area. Word data was accessed to an oddnumbered address. Longword data was accessed to an oddnumbered address. Processing in Continuation Mode Operates in the same way as the actual device. Error Message Address Error Memory Access Error Access to a memory area that has not been allocated On memory write, nothing is written; on memory read, all bits Write to a memory area having the write are read as 1. protect attribute Read from a memory area having the read disable attribute Access to an area where memory does not exist Data was written to EEPROM with an instruction other than EEPMOV. Illegal Instruction A code other than an instruction was executed. Always stops. MOV.B Rn, @-SP or MOV.B @SP+, Rn Continues operation; the result is was executed. not guaranteed. Illegal Operation In the DAA or DAS instruction, relationship between the C and H flags of CCR, and their relation to the value before compensation were incorrect. Zero-division or overflow was caused by the DIVXU or DIVXS instruction. Continues operation; the result is not guaranteed. When a simulation error occurs in the stop mode, the simulator/debugger returns to the command wait state after stopping instruction execution and displaying the error message. Table 3.6 lists the states of the program counter (PC) at simulation error stop. The status register (SR) value does not change at simulation error stop. Rev. 6.0, 09/00, page 27 of 187 Table 3.6 Register States at Simulation Error Stop PC Value * * When an instruction is read: The start address of the instruction that caused the error. When an instruction is executed: The instruction address following the instruction that caused the error. Error Message Address Error, Memory Access Error Illegal Instruction Illegal Operation The start address of the instruction that caused the error. The instruction address following the instruction that caused the error. Use the following procedure when debugging programs which include instructions that generate simulation errors. a. First execute the program in the stop mode and confirm that there are no errors except those in the intended locations. b. After confirming the above, execute the program in the continuation mode. Note: If an error occurs in the stop mode and simulation is continued after changing the simulator mode to the continuation mode, simulation may not be performed correctly. When restarting a simulation, always restore the register contents and the memory contents to the state prior to the occurrence of the error. 3.10.3 Break Due to a Trace Buffer Overflow After the [Break] mode is specified with [Trace buffer full handling] in the Trace Acquisition dialog box, the simulator/debugger stops execution when the trace buffer becomes full. The following message is displayed when execution is stopped. Trace Buffer Full 3.10.4 Break Due to Execution of the SLEEP Instruction When the SLEEP instruction is executed during instruction execution, the simulator/debugger stops execution. The following message is displayed when execution is stopped. Sleep Note: When restarting execution, change the PC value to the instruction address at the restart location. Rev. 6.0, 09/00, page 28 of 187 3.10.5 Break Due to the [STOP] Button Users can forcibly terminate execution by clicking the [STOP] button during instruction execution. The following message is displayed when execution is terminated. Stop Execution can be resumed with the GO or STEP command. 3.11 Floating-Point Data Floating-point numbers can be displayed and input for the following real-number data, which makes floating-point data processing easier. * Data in the Set Break dialog box when the break type is set to [Break Data] or [Break Register] * Data in the Memory window * Data in the Fill Memory dialog box * Data in the Search Memory dialog box The floating-point data format conforms to the ANSI C standard. In the simulator/debugger, the rounding mode for floating-point decimal-to-binary conversion can be selected in the System Configuration dialog box. One of the following two modes can be selected: * Round to nearest (RN) * Round to zero (RZ) If a denormalized number is specified for binary-to-decimal or decimal-to-binary conversion, it is converted to zero in RZ mode, and it is left as a denormalized number in RN mode. If an overflow occurs during decimal-to-binary conversion, the maximum floating-point value is returned in RZ mode, and the infinity is returned in RN mode. 3.12 Display of Function Call History The simulator/debugger displays the function call history in the Stack Trace window when simulation stops, which enables program execution flow to be checked easily. Selecting a function name in the Stack Trace window displays the corresponding source program in the Source window; the function that has called the current function can also be checked. The displayed function call history is updated in the following cases: Rev. 6.0, 09/00, page 29 of 187 * When simulation stops under the break conditions described in section 3.10, Break Conditions. * When register values are modified while simulation stops due to the above break conditions. * While single-step execution is performed.
