Section 1 Connecting the Emulator with the User System
1.2
Connecting the Emulator with the User System
To connect the E10A-USB emulator (hereinafter referred to as the emulator), the H-UDI port connector must be installed on the user system to connect the user system interface cable. When designing the user system, refer to the recommended circuit between the H-UDI port connector and the MCU. In addition, read the E10A-USB emulator user's manual and hardware manual for the related device. Table 1.2 shows the type number of the emulator, the corresponding connector type, and the use of AUD function. Table 1.2 Type Number, AUD Function, and Connector Type
Type Number HS0005KCU02H HS0005KCU01H, HS0005KCU02H HS0005KCU02H Connector 36-pin connector 14-pin connector 38-pin connector AUD Function Available Not available Available
The H-UDI port connector has the 36-pin, 14-pin, and 38-pin types as described below. Use them according to the purpose of the usage. 1. 36-pin type (with AUD function; compatible with the E200F emulator) The AUD trace function is supported. A large amount of trace information can be acquired in realtime. The window trace function is also supported for acquiring memory access in the specified range (memory access address or memory access data) by tracing. 2. 14-pin type (without AUD function) The AUD trace function cannot be used because only the H-UDI function is supported. Since the 14-pin type connector is smaller than the 36-pin type (1/2.5), the size of the area where the connector is installed on the user system can be reduced. 3. 38-pin type (with AUD function) The AUD trace function is supported. As well as the 36-pin type, a large amount of trace information can be acquired in realtime. Since the 38-pin type connector is smaller than the 36-pin type (1/2.5), the size of the area where the connector is installed on the user system can be reduced. To use the 38-pin type connector, however, an optional cable (HS0005ECK01H) is required.

Manufacturer Hirose Electric Co., Ltd. Specifications Screw type Lock-pin type 14-pin straight type 38-pin Mictor type
Note: When designing the 36-pin connector layout on the user board, do not connect any components under the H-UDI connector. When designing the 14-pin connector layout on the user board, do not place any components within 3 mm of the H-UDI port connector. When designing the 38-pin connector layout on the user board, reduce cross-talk noise etc. by keeping other signal lines out of the region where the H-UDI port connector is situated. As shown in figure 1.1, an upper limit (5 mm) applies to the heights of components mounted around the user system connector.

Recommended Circuit between the H-UDI Port Connector and the MCU
Recommended Circuit (36-Pin Type)
1.5.1
Figure 1.5 shows a recommended circuit for connection between the H-UDI and AUD port connectors (36 pins) and the MCU when the emulator is in use. Notes: 1. Do not connect anything to the N.C. pins of the H-UDI port connector. 2. The ASEMD pin must be 1 when the emulator is connected and 0 when the emulator is not connected, respectively. (1) When the emulator is used: ASEMD = 1 (2) When the emulator is not used: ASEMD = 0 Figure 1.5 shows an example of circuits that allow the ASEMD pin to be changed by switches, etc. 3. When a network resistance is used for pull-up, it may be affected by a noise. Separate TCK from other resistances. 4. The pattern between the H-UDI port connector and the MCU must be as short as possible. Do not connect the signal lines to other components on the board. 5. The AUD signals (AUDCK, AUDATA3 to AUDATA0, and AUDSYNC#) operate in high speed. Isometric connection is needed if possible. Do not separate connection nor connect other signal lines adjacently. 6. Since the H-UDI and the AUD of the MCU operate with the Vcc, supply only the Vcc to the UVCC pin. Make the emulator's switch settings so that the user power will be supplied (SW2 = 1 and SW3 = 1). 7. The resistance value shown in figure 1.5 is for reference. 8. For the AUDCK pin, guard the pattern between the H-UDI port connector and the MCU at GND level. 9. The TRST# pin must be at the low level for a certain period when the power is supplied whether the H-UDI is used or not. 10. For the pin processing in cases where the emulator is not used, refer to the hardware manual of the related MCU.

2.1 Differences between the MCU 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 values of the MCU are undefined. When the emulator is initiated from the workspace, a value to be entered is saved in a session. Table 2.1 Register Initial Values at Emulator Link Up
Register R0 to R14 R15 (SP) PC SR GBR VBR TBR MACH MACL PR FPSCR* FPUL* FPR0-15* Emulator at Link Up H'00000000 Value of the SP in the power-on reset vector table Value of the PC in the power-on reset vector table H'000000F0 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00040001 H'00000000 H'00000000
Note: If the MCU does not incorporate the floating-point unit (FPU), these registers are not displayed.
Note: When a value of the interrupt mask bit in the SR register is changed in the [Registers] window, it is actually reflected in that register immediately before execution of the user program is started. It also applies when the value is changed by the REGISTER_SET command. 2. The emulator uses the H-UDI; do not access the H-UDI.

3. Low-Power States When the emulator is used, the sleep state can be cleared with either the clearing function or with the [STOP] button, and a break will occur. Emulation of the hardware stand-by mode is not supported. Do not stop inputting the clock to the H-UDI module by using the module standby function. 4. Reset Signals The MCU reset signals are only valid during emulation started with clicking the GO or STEPtype button. If these signals are enabled on the user system in command input wait state, they are not sent to the MCU. Note: Do not break the user program when the /RES, /BREQ, or /WAIT signal is being low. A TIMEOUT error will occur. If the /BREQ or /WAIT signal is fixed to low during break, a TIMEOUT error will occur at memory access. 5. 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. 6. Memory Access during User Program Execution During execution of the user program, memory is accessed by the following two methods, as shown in table 2.2. Table 2.2 Memory Access during User Program Execution
Method H-UDI read/write Short break Description The stopping time of the user program is short because memory is accessed by the dedicated bus master. This method is not available for this product (do not set short break).
The method for accessing memory during execution of the user program is specified by using the [Configuration] dialog box.

7. Memory Access to the External Flash Memory Area The emulator can download the load module to the external flash memory area (for details, TM refer to section 6.22, Download Function to the Flash Memory Area, in the SuperH Family E10A-USB Emulator User's Manual). 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. 8. ROM Cache For ROM cache in the MCU, the emulator operates as shown in table 2.4. Table 2.4
Function Write and erase of the flash memory Download of the program to the flash memory Set an overlap of ERAM to the flash memory* Change of the setting of an overlap of ERAM to the flash memory* Download of a program to ERAM overlapped with the flash memory* Rewrite of the memory contents of ERAM overlapped with the flash memory* Set a software break to the flash memory and ERAM overlapped with the flash memory* Memory read Accesses the disabled cache area to read the content of internal flash memory.

Note: If the target device is the SH72544R, SH72543R, or SH72531, the function for setting the emulation RAM is not supported.
9. Using WDT The WDT does not operate during break. 10. 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 HS0005KCU01H or HS0005KCU02H is used: TCK = 10 MHz 11. [IO] Window Display and modification For each watchdog timer register, there are two registers to be separately used for write and read operations. Table 2.5 Watchdog Timer Register

Customization of the I/O-register definition file The internal I/O registers can be accessed from the [IO] window. After the I/O-register definition file is created, the MCU's specifications 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. However, the emulator does not support the bit-field function. Verify In the [IO] window, the verify function of the input value is disabled.

12. Illegal Instructions Do not execute illegal instructions with STEP-type commands. 13. Reset Input During execution of the user program, the emulator may not operate correctly if a contention occurs between the following operations for the emulator and the reset input to the target device: Setting an Event Condition Setting an internal trace Displaying the content acquired by an internal trace Reading or writing of a memory Note that those operations should not contend with the reset input to the target device. 14. MCU Operating Mode Boot mode is not supported in the SH72546RFCC, SH72544R, SH72543R, SH72531FCC, and SH72531. When starting up in the user boot mode, do not set a software break point. Use an event point.

Event Condition Functions
2.2.1
The emulator is used to set event conditions for the following three functions: * Break of the user program * Internal trace * Start or end of performance measurement Table 2.6 lists the types of Event Condition. Table 2.6 Types of Event Condition
Event Condition Type Address bus condition (Address) Description Sets a condition when the address bus (data access) value or the program counter value (before or after execution of instructions) is matched. Sets a condition when the data bus value is matched. Byte, word, or longword can be specified as the access data size. There are two bus state condition settings: Bus state condition: Sets a condition when the data bus value is matched. Read/Write condition: Sets a condition when the read/write condition is matched. Count Reset point Action Sets a condition when the specified other conditions are satisfied for the specified counts. A reset point is set when the count and the sequential condition are specified. Selects the operation when a condition (such as a break, a trace halt condition, or a trace acquisition condition) is matched.
Data bus condition (Data) Bus state condition (Bus State)
Using the [Combination action (Sequential or PtoP)] dialog box specifies the sequential condition, the point-to-point of the internal trace, and the start or end of performance measurement. Table 2.7 lists the combinations of conditions that can be set under Ch1 to Ch11.

(2) Usage Example of Sequential Break Extension Setting A tutorial program provided for the product is used as an example. For the tutorial program, refer TM to section 6, Tutorial, in the SuperH Family E10A-USB Emulator User's Manual. The conditions of Event Condition are set as follows: 1. Ch3 Breaks address H'00001088 when the condition [Only program fetched address after] is satisfied. 2. Ch2 Breaks address H'000010B0 when the condition [Only program fetched address after] is satisfied. 3. Ch1 Breaks address H'000010F2 when the condition [Only program fetched address after] is satisfied. Note: Do not set other channels. 4. Sets the content of the [Ch1,2,3] list box to [Break: Ch 3-2-1] in the [Combination action (Sequential or PtoP)] dialog box. 5. Enables the condition of Event Condition 1 from the popup menu by clicking the right mouse button on the [Event Condition] sheet. Then, set the program counter and stack pointer (PC = H'00000800, R15 = H'FFF90000) in the [Registers] window and click the [Go] button. If this does not execute normally, issue a reset and execute the above procedures. The program is executed up to the condition of Ch1 and halted. Here, the condition is satisfied in the order of Ch3 -> 2 -> 1.

Figure 2.1 [Source] Window at Execution Halted (Sequential Break) If the sequential condition, performance measurement start/end, or point-to-point for the internal trace is set, conditions of Event Condition to be used will be disabled. Such conditions must be enabled from the popup menu by clicking the right mouse button on the [Event Condition] sheet. Notes: 1. If the Event condition is set for the slot in the delayed branch instruction by the program counter (after execution of the instruction), the condition is satisfied before executing the instruction in the branch destination (when a break has been set, it occurs before executing the instruction in the branch destination). 2. Do not set the Event condition for the SLEEP instruction by the program counter (after execution of the instruction). 3. When the Event condition is set for the 32-bit instruction by the program counter, set that condition in the upper 16 bits of the instruction. 4. If the power-on reset and the Event condition are matched simultaneously, no condition will be satisfied. 5. Do not set the Event condition for the DIVU or DIVS instruction by the program counter (after execution of the instruction). 6. If a condition of which intervals are satisfied closely is set, no sequential condition will be satisfied. * Set the Event conditions, which are satisfied closely, by the program counter with intervals of two or more instructions. * After the Event condition has been matched by accessing data, set the Event condition by the program counter with intervals of 17 or more instructions.

7. If the settings of the Event condition or the sequential conditions are changed during execution of the program, execution will be suspended. (The number of clocks to be suspended during execution of the program is a maximum of about 18 peripheral clocks (P). If the peripheral clock (P) is 66.6 MHz, the program will be suspended for 0.27 s.) 8. If the settings of Event conditions or the sequential conditions are changed during execution of the program, the emulator temporarily disables all Event conditions to change the settings. During this period, no Event condition will be satisfied. 9. If the break condition before executing an instruction is set to the instruction followed by DIVU and DIVS, the factor for halting a break will be incorrect under the following condition: * If a break occurs during execution of the above DIVU and DIVS instructions, the break condition before executing an instruction, which has been set to the next instruction, may be displayed as the factor for halting a break. 10. If the break conditions before and after executing instructions are set to the same address, the factor for halting a break will be incorrectly displayed. The factor for halting a break due to the break condition after executing an instruction will be displayed even if a break is halted by the break condition before executing an instruction. 11. Do not set the break condition after executing instructions and BREAKPOINT (software break) to the same address. 12. When the emulator is being connected, the user break controller (UBC) function is not available. 13. The performance-measurement function is not available for the SH72544R, SH72543R, and SH72531, so do not make the settings "Ch2 to Ch1PA" and "Ch1 to Ch2PA" if this device is in use. 2.2.2 Trace Functions

Using Event Condition restricts the condition; the following three items are set as the internal trace conditions. Table 2.12 Trace Conditions of the Internal Trace
Item Trace halt Acquisition Information Acquires the internal trace until the Event Condition is satisfied. (The trace content is displayed in the [Trace] window after a trace has been halted. No break occurs in the user program.) Acquires only the data access where the Event Condition is satisfied. Traces the period from the satisfaction of Event Condition 5 to the satisfaction of Event Condition 4.
Trace acquisition Point-to-point
To restrict trace acquisition to access for only a specific address or specific function of a program, an Event Condition can be used. Typical examples are described below. * Example of halting a trace with a write access (M-bus) to H'FFF80000 by the user program as a condition (trace halt): Set the condition to be acquired on [I-Trace mode]. Set the following in the [Event Condition 1] or [Event Condition 2] dialog box: Address condition: Set [Address] and H'FFF80000. Bus state condition: Set [M-Bus] and [Write]. Action condition: Deselect the [Acquire Break] checkbox and select [Stop] from the [Acquire Trace] list box. * Example of acquiring the write access (M-bus) only to H'FFF80000 by the user program (trace acquisition condition): Select [M-Bus & Branch] from [Type] and enable [Write] on [Acquisition]. Set the following in the [Event Condition 1] or [Event Condition 2] dialog box: Address condition: Set [Address] and H'FFF80000. Bus state condition: Set [M-Bus] and [Write]. Action condition: Deselect the [Acquire Break] checkbox and select [Condition] from the [Acquire Trace] list box. For the trace acquisition condition, the condition to be acquired by Event Condition should be acquired by [I-Trace mode]. * Example of acquiring a trace for the period while the program passes H'1000 through H'2000 (point-to-point):

Set the condition to be acquired on [I-Trace mode]. Set the address condition as H'1000 in the [Event Condition 5] dialog box. Set the address condition as H'2000 in the [Event Condition 4] dialog box. Set [I-Trace] as [Ch5 to Ch4 PtoP] in the [Combination action (Sequential or PtoP)] dialog box. When point-to-point and trace acquisition condition are set simultaneously, they are ANDed. (2) Notes on Internal Trace
* Timestamp The timestamp is the clock counts of P (48-bit counter). Table 2.13 shows the timing for acquiring the timestamp. Table 2.13 Timing for the Timestamp Acquisition
Item Acquisition Information Counter Value Stored in the Trace Memory Counter value when data access (read or write) has been completed Counter value when the next bus cycle has been completed after a branch Fetch Data access F-bus Fetch Counter value when a fetch has been completed Counter value when data access has been completed Counter value when a fetch has been completed
M-bus data access Branch I-bus
* Point-to-point The trace-start condition is satisfied when the specified instruction has been fetched. Accordingly, if the trace-start condition has been set for the overrun-fetched instruction (an instruction that is not executed although it has been fetched at a branch or transition to an interrupt), tracing is started during overrun-fetching of the instruction. However, when overrun-fetching is achieved (a branch is completed), tracing is automatically suspended. If the start and end conditions are satisfied closely, trace information will not be acquired correctly. The execution cycle of the instruction fetched before the start condition is satisfied may be traced. When the I-bus is acquired, do not specify point-to-point. Memory access may not be acquired by the internal trace if it occurs at several instructions immediately before satisfaction of the point-to-point end condition.

Section 2 Software Specifications when Using the SH72546RFCC, SH72544R, SH72543R, SH72531FCC, and SH72531
* Halting a trace Do not set the trace end condition for the sleep instruction and the branch instruction that the delay slot becomes the sleep instruction. * Trace acquisition condition Do not set the trace end condition for the sleep instruction and the branch instruction according to which the delay slot becomes the sleep instruction. When [F-Bus], [F-Bus, M-Bus & Branch], or [I-Bus, F-Bus] is selected, do not set the trace acquisition condition for [Event Condition 1] and [Event Condition 2]. If a trace acquisition condition is set, no trace will be acquired. When [I-Bus, M-Bus & Branch] is selected and the trace acquisition condition is set for the Mbus and I-bus with Event Condition, set the M-bus condition and the I-bus condition for [Event Condition 1] and [Event Condition 2], respectively. When matching of the program counter value is a condition of Event Condition for internal trace acquisition (i.e. [Only program fetched address] or [Only program fetched address after] is selected), do not specify addresses in the on-chip ROM or on-chip RAM as the address condition. If you specify a break (by selecting the [Acquire Break] checkbox) and trace acquisition (by selecting [Condition] from the [Acquire Trace] list box) on the [Action] page as the action to take when a condition of Event Condition is satisfied, setting of the trace acquisition will be ignored. If the settings of [I-Trace mode] are changed during execution of the program, execution will be suspended. (The number of clocks to be suspended during execution of the program is a maximum of about 24 peripheral clocks (P). If the peripheral clock (P) is 66.6 MHz, the program will be suspended for 0.36 s.) * Displaying a trace If a trace is displayed during execution of the program, execution will be suspended to acquire the trace information. (The number of clocks to be suspended during execution of the program is a maximum of about 5120 peripheral clocks (P). If the peripheral clock (P) is 66.6 MHz, the program will be suspended for 76.87 s.) * Branch trace If breaks occur immediately after executing non-delayed branch and TRAPA instructions and generating a branch due to exception or interrupt, a trace for one branch will not be acquired immediately before such breaks. However, this does not affect on generation of breaks caused by a BREAKPOINT and a break before executing instructions of Event Condition.

* Writing memory immediately before generating a break If an instruction is executed to write memory immediately before generating a break, trace acquisition may not be performed. * Internal trace function is not available for the SH72544R, SH72543R, and SH72531. (3) AUD Trace Functions
This function is operational when the AUD pin of the device is connected to the emulator. Table 2.14 shows the AUD trace acquisition mode that can be set in each trace function. Table 2.14 AUD Trace Acquisition Mode
Type Continuous trace occurs Mode Realtime trace Description When the next branch occurs while the trace information is being output, all the information may not be output. The user program can be executed in realtime, but some trace information will be lost. When the next branch occurs while the trace information is being output, the CPU stops operations until the information is output. The user program is not executed in realtime. This function overwrites the latest trace information to store the oldest trace information. After the trace buffer becomes full, the trace information is no longer acquired. The user program is continuously executed.

Note: When [M-Bus] or [I-Bus] is selected, the following bus cycles will be traced. * M-Bus: A bus cycle generated by the CPU is acquired. * I-Bus: A bus cycle generated by the CPU or DMA is acquired. (c) Software Trace Function
Note: This function can be supported with SHC/C++ compiler (manufactured by Renesas Technology Corp.; including OEM and bundle products) V7.0 or later. When a specific instruction is executed, the PC value at execution and the contents of one general register are acquired by trace. Describe the Trace(x) function (x is a variable name) to be compiled and linked beforehand. For details, refer to the SHC manual. When the load module is downloaded on the target system and is executed while a software trace function is valid, the PC value that has executed the Trace(x) function, the general register value for x, and the source lines are displayed. To activate the software trace function, select the [Software trace] check box in the [AUD function] group box of the [Trace mode] page. (4) Notes on AUD Trace
1. When the trace display is performed during user program execution, the mnemonics, operands, or source is not displayed. 2. The AUD trace function outputs the differences between newly output branch source addresses and previously output branch source addresses. The window trace function outputs the differences between newly output addresses and previously output addresses. If the previous branch source address is the same as the upper 16 bits, the lower 16 bits are output. If it matches the upper 24 bits, the lower 8 bits are output. If it matches the upper 28 bits, the lower 4 bits are output. The emulator regenerates the 32-bit address from these differences and displays it in the [Trace] window. If the emulator cannot display the 32-bit address, it displays the difference from the previously displayed 32-bit address. 3. If the 32-bit address cannot be displayed, the source line is not displayed. 4. If a completion-type exception occurs during exception branch acquisition, the next address to the address in which an exception occurs is acquired. 5. The AUD trace is disabled while the profiling function is used. 6. Set the AUD clock (AUDCK) frequency to 40 MHz or lower. If the frequency is higher than 40 MHz, the emulator will not operate normally.

Section 2 Software Specifications when Using the SH72546RFCC, SH72544R, SH72543R, SH72531FCC, and SH72531
7. If breaks occur immediately after executing non-delayed branch and TRAPA instructions and generating a branch due to exception or interrupt, a trace for one branch will not be acquired immediately before such breaks. However, this does not affect on generation of breaks caused by a BREAKPOINT and a break before executing instructions of Event Condition. 8. For the result by software trace, a value in the [Data] item is not correct (that value is correct for window trace). 9. The AUD trace function is not available if the target device is the SH72531FCC or SH72531. 10. The CPU clock ratios 1:1 and 1:2 cannot be used for the AUD clock (AUDCK) with the SH72546RFCC, SH72544R, or SH72543R as the target device. 2.2.3 Notes on Using the JTAG (H-UDI) Clock (TCK)
1. Set the JTAG clock (TCK) frequency to lower than the frequency of the peripheral module clock. 2. The initial value of the JTAG clock (TCK) is 10 MHz. 3. A value to be set for the JTAG clock (TCK) is initialized after executing [Reset CPU] or [Reset Go]. Thus the TCK value will be the initial value. 2.2.4 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. It cannot be set to the following addresses: An area other than CS and the internal RAM An instruction in which Break Condition 2 is satisfied A slot instruction of a delayed branch instruction 3. During step operation, specifying BREAKPOINTs and Event Condition breaks are disabled. 4. When execution resumes from the address where a BREAKPOINT is specified and a break occurs before Event Condition execution, single-step operation is performed at the address before execution resumes. Therefore, realtime operation cannot be performed. 5. 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. 6. If an address of a BREAKPOINT cannot be correctly set in the ROM or flash memory area, a mark will be displayed in the [BP] area of the address on the [Source] 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 event condition, the mark disappears.
2.2.5
Notes on Setting the [Event Condition] Dialog Box and the BREAKCONDITION_ SET Command
1. When [Go to cursor], [Step In], [Step Over], or [Step Out] is selected, the settings of Event Condition 3 are disabled. 2. When an Event Condition is satisfied, emulation may stop after two or more instructions have been executed. 2.2.6 Performance Measurement Function
The emulator supports the performance measurement function. Note: The performance measurement function is not available when the target device is the SH72544R, SH72543R, or SH72531. (1) Setting the Performance Measurement Conditions
To set the performance measurement conditions, use the [Performance Analysis] dialog box and the PERFORMANCE_SET command. When any line in the [Performance Analysis] window is clicked with the right mouse button, a popup menu is displayed and the [Performance Analysis] dialog box can be displayed by selecting [Setting]. Note: For the command line syntax, refer to the online help.

Emulation RAM Setting Function
The emulation RAM can be set in the [Memory Mapping] dialog box which is opened by selecting [Setup] -> [Emulator] -> [Memory...] from the menu. The emulator incorporates 8-block emulation RAM in each 64-kbyte unit, which can be set in each 64-kbyte boundary within the address ranges from H'00000000 to H'001FFFFF. The emulation RAM is overlapped with the address of the internal flash memory. Using the emulation RAM proceeds debugging without rewriting the program or data on the internal flash memory. When the emulation RAM is not used in the emulator, it can be used as the internal RAM for debugging.
