Connecting the E10A Emulator with the User System

To connect the E10A 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 emulator user's manual and hardware manual for the related device. Table 1.2 shows the type number of the emulator and the corresponding connector type.

Recommended Circuit

1.5.1

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

2.1 Differences between the SH7615 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 actual SH7615 registers 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 MACH MACL PR RS RE MOD A0G, A1G A0, A1 X0, X1 Y0, Y1 M0, M1 DSR Emulator at Link Up H'00000000 Value of the SP in the vector address table Value of the PC in the vector address table H'000000F0 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000 H'00000000

2. The emulator uses the H-UDI; do not access the H-UDI.

3. Low-Power States (Sleep and Standby) For low-power consumption, the SH7615 has sleep and standby modes. The sleep and standby modes are switched using the SLEEP instruction. The sleep mode can be cleared by either normal clearing or by the satisfaction of a break condition (including BREAK key input), and the user program breaks. The standby mode can be cleared with the normal clearing function, and after the standby mode is cleared, the user program operates correctly. Note that, however, if a command has been entered in standby mode, no commands can be used from the emulator after the standby mode is cleared. The states cannot be canceled by the [STOP] button. Notes: 1. After the sleep mode is cleared by a break, execution restarts at the instruction following the SLEEP instruction. 2. If the memory is accessed or modified in sleep mode, the sleep mode is cleared and execution starts at the instruction following the SLEEP instruction.

4. /RES Signal The SH7615 /RES signal is only valid during user program execution started with clicking the GO or STEP-type button. If this signal is enabled on the user system in command input wait state, it is not sent to the SH7615. Note: Do not start user program execution or access the memory while the control input signal (/RES, /WAIT, or /BRLS) is being low. A TIMEOUT error will occur. 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. Note: If the DMAC transfer is in the burst mode and the transfer size is 4 Mbytes or more, a TIMEOUT error will occur. 6. Memory Access during User Program Execution When a memory is accessed from the memory window, etc. during user program execution, the user program is resumed after it has stopped in the emulator to access the memory. Therefore, realtime emulation cannot be performed. The stopping time of the user program is as follows: Environment: Host computer: 650 MHz (Pentium III) SH7615: 50 MHz (CPU clock) JTAG clock: 7.5 MHz When a one-byte memory is read from the command-line window, the stopping time will be about 32 ms.

7. Memory Access during User Program Break The emulator can download the program for the flash memory area (refer to section 6.22, TM Download Function to the Flash Memory Area, in the Debugger Part of the SuperH Family E10A Emulator Users 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. 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. 9. 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 HS7615KCI01H is used: TCK = 4.125 MHz When HS7615KCM01H is used: TCK = 3.75 MHz 10. [IO] Window Display and modification Do not change values of the User Break Controller because it is used by the emulator. For each Watchdog Timer register, there are two registers to be separately used for write and read operations. Table 2.2 Watchdog Timer Register
Register Name WTCSR(W) WTCNT(W) WTCSR(R) WTCNT(R) Usage Write Write Read Read Register Watchdog timer control/status register Watchdog timer counter Watchdog timer control/status register Watchdog timer counter

The watchdog timer operates only when the user program is executed. Do not change the value of the frequency change register in the [IO] window or [Memory] window. The internal I/O registers can be accessed from the [IO] window. After the I/O-register definition file is created, the MPUs specification may be changed. If each I/O register in the I/O-register definition file differs from addresses described in the hardware manual, change the I/O-register definition file according to the description in the hardware manual. The I/O-register definition file can be customized depending on its format. Note that, however, the emulator does not support the bit-field function.

Verify In the [IO] window, the verify function of the input value is disabled.

11. Illegal Instructions If illegal instructions are executed by STEP-type commands, the emulator cannot go to the next program counter. 12. Interrupts While the emulator is executing the user program, any interrupt to the SH7615 can be used. While the emulator is waiting for command input, interrupts are not processed. However, if an edge sensitive interrupt occurs in command input wait state, the emulator holds the interrupt and executes the interrupt processing routine when the GO command is entered. 13. When accessing the reserved memory area, use the [Memory] window; do not use other windows.

Break Condition Functions

In the emulator, four break conditions can be set (Break Condition 1,2,3,4). Table 2.4 lists the items that can be specified for each. Table 2.4 Types of Break Conditions
Break Condition Type Address bus condition (Address) Data bus condition (Data) Description Breaks when the SH7615 address bus value matches the specified value. Breaks when the SH7615 data bus value matches the specified value. Byte, word, or longword can be specified as the access data size. Breaks in the read or write cycle. Breaks when the bus cycle is the specified cycle. Breaks when the conditions set are satisfied the specified number of times.

Trace Functions

The trace function in the emulator uses the branch-instruction trace function in the SH7615. It displays the branch-source and branch-destination addresses, the mnemonic, operand, and trace information can be acquired in realtime. Notes: 1. The trace information on the four latest branch instructions can be acquired. This includes the information when execution branches from the emulator program to the user program. Therefore, when four or more branches occur, the four latest branch instructions are acquired; when three or less branches occur, the information on the branch from the emulator program to the user program is displayed.
12

2. The emulator address may be displayed in the [Trace] window at the last address when the user program is stopped. In such a case, the following message will be displayed. Ignore this address because it is not a user-program-related address. *** EML *** 2.2.4 Notes on Using the JTAG Clock (TCK)

1. Set the JTAG clock (TCK) frequency to lower than the frequency of the SH7615 peripheral module clock (CKP). 2. Do not set the following values for the JTAG clock (TCK): When HS7615KCM01H is used: 15 MHz When HS7615KCI01H is used: 16.5 MHz 2.2.5 Notes on Setting the [Breakpoint] Dialog Box

1. When an odd address is set, the next lowest even address is used. 2. A BREAKPOINT is accomplished by replacing instructions. Accordingly, it can be set only to the RAM area. However, a BREAKPOINT cannot be set to the following addresses: An address whose memory content is H'0000 An area other than RAM An area of address H40000000 and the followings An instruction in which Break Condition 4 is satisfied A slot instruction of a delayed branch instruction A lower 16-bit address of the 32-bit DSP instruction 3. During step operation, BREAKPOINTs are disabled. 4. Conditions set at Break Condition 4 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 4 is satisfied. 5. When execution resumes from the breakpoint address after the program execution stops at the breakpoint, single-step operation 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 exceptions of the illegal slot instruction occur although the program does not stop. Accordingly, do not set a BREAKPOINT to the slot instruction of a delayed branch instruction. 7. If a BREAKPOINT is set at a part of the repeating instructions where the BRA instruction cannot be set, it is handled as the general illegal instruction. In addition, because of the instruction restriction in the repeating loop, a break may or may not occur. Before and after the start or end of the loop, interrupts may not be accepted. 8. Settings of BREAKPOINT and Break Condition 1,2,3,4 are invalid while the STEP OVER function is being used.
13

9. 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. 10. 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 [Editor] or [Disassembly] window by refreshing the [Memory] window, etc. after Go execution. However, no break will occur at this address. When the program halts with the break condition, the mark disappears. 2.2.6 Notes on Setting the [Break Condition] Dialog Box and BREAKCONDITION_SET Command 1. When [Step In], [Step Over], or [Step Out] is selected, the settings of Break Condition 4 are disabled. 2. Break Condition 4 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 4. When a Break Condition is satisfied, emulation may stop after two or more instructions have been executed. 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. Settings of BREAKPOINT and Break Condition 1,2,3,4 are disabled while the STEP OVER function is being used.
