Section 1 Connecting the Emulator with the User System

1.2 Connecting the Emulator with the User System

To connect the E200F 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

MPU.

It is impossible to connect this emulator to the 14-pin and 36-pin connectors that are recommended for the E10A-USB emulator. The 38-pin connector has the same specification as the optional 38-pin connector for the E10A-USB emulator. When designing the user system, read the E200F emulator user's manual and the hardware manual for the relevant device.

H-UDI port connectors are of the 38-pin, 36-pin, and 14-pin types described below. Use the 38pin type with the SH7781 E200F emulator.

1. 38-pin type (with AUD function, and supporting high-density mounting and high-speed operation)

This connector supports high-density mounting and high-speed operation. A large amount of trace information can be acquired in realtime by the AUD trace function. This connector also supports window tracing for the acquisition of memory data in a specified range (accessed addresses and data in memory access).

2. 36-pin type (with AUD function)

The AUD trace function is supported. A large amount of trace information can be acquired in realtime. This connector also supports window tracing for the acquisition of memory data in a specified range (accessed addresses and data in memory access). The 36-pin connector cannot be used for connection of the SH7781 E200F emulator. Instead, this connector is for use with the E10A-USB emulator (with AUD function).

3. 14-pin type (without AUD function)

The AUD trace function cannot be used because only the H-UDI function is supported. This connector cannot be used for connection of the SH7781 E200F emulator. Instead, this connector is for use with the E10A-USB emulator.

Section 1 Connecting the Emulator with the User System

1.5 Recommended Circuit between the H-UDI Port Connector and the

MPU

1.5.1 Recommended Circuit (38-Pin Type)

Figure 1.2 shows a recommended circuit for connection between the H-UDI port connector (38 pins) and the MPU 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 MPMD pin must be 0 when the emulator is connected and 1 when the emulator is not connected, respectively.

(1) When the emulator is used: MPMD = 0

(2) When the emulator is not used: MPMD = 1

Figure 1.2 shows an example of circuits that allow the MPMD pin to be GND (0) whenever the emulator is connected by using the user system interface cable.

3. When a network resistance is used for pull-up, it may be affected by a noise. Separate

TCK from other resistances.

4. The /TRST pin must be at the low level for a certain period when the power is supplied regardless of whether the H-UDI is used or not.

5. The pattern between the H-UDI port connector and the MPU must be as short as possible. Do not connect the signal lines to any other components on the board.

6. Since the H-UDI and AUD of the MPU operates with the VDDQ (3.3 V) voltage, supply only the VDDQ (3.3 V) voltage to the UVCC pin.

7. The resistance value shown in figure 1.2 is for reference.

8. For the pin processing in cases where the emulator is not used, refer to the hardware manual of the related MPU.

9. For the AUDCK pin, guard the pattern between the H-UDI port connector and the

MPU at GND level.

Section 2 Software Specifications when Using the SH7781

3. Low-Power States (Sleep and Module Standby)

For low-power consumption, the SH7781 has sleep and module standby states.

The sleep and module standby states are switched using the SLEEP instruction. When the emulator is used, the sleep state can be cleared with either the normal clearing function or with the [STOP] button, and a break will occur.

Note: The memory must not be accessed or modified in sleep state.

4. Reset Signals

The SH7781 reset signals are only valid during emulation started with clicking the GO or

STEP-type button. If these signals are enabled on the user system in command input wait state, they are not sent to the SH7781.

Note: Do not break the user program when the _PRESET or _BREQ signal is being low and the

WAIT control signal is being active. A TIMEOUT error will occur. If the WAIT control signal and the _BREQ signal are fixed to active and low during break, respectively, 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

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: 800 MHz (Pentium ® III)

JTAG clock: 30 MHz (TCK clock)

When a one-byte memory is read from the command-line window, the stopping time will be about 45 ms.

7. Memory Access during User Program Break

The emulator can download the program for the flash memory area (for details, refer to section

6.22, Download Function to the Flash Memory Area, in the SH-4A, SH4AL-DSP E200F

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. 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 issues a single write to outside. The LRU is not updated.

⎯ At memory read: Reads memory from the cache. The LRU is not updated.

Therefore, when memory read or write is performed during user program break, the cache state does not change.

⎯ At breakpoint set: Disables the instruction cache.

9. Port

The AUD pin is multiplexed as shown in table 2.2.

Table 2.2 Multiplexed Functions

Port 1

Function 1

FALE

Function 2

AUDCK

Port 2 _DRAK2/_CE2A AUDCK

Note: Function 1 can be used when the AUD pins of the device are not connected to the emulator. When the AUD trace is enabled, the emulator changes settings so that function 2 is forcibly used.

10. UBC

When [User] is specified in the [UBC mode] list box in the [Configuration] dialog box, the

UBC can be used in the user program.

Do not use the UBC in the user program as it is used by the emulator when [EML] is specified in the [UBC mode] list box in the [Configuration] dialog box.

REJ10J1422-0200

Section 2 Software Specifications when Using the SH7781

11. Memory Access during Break

In the enabled MMU, when a memory is accessed and a TLB error occurs during break, it can be selected whether the TLB exception is controlled or the program jumps to the user exception handler in [TLB Mode] in the [Configuration] dialog box. When [TLB miss exception is enable] is selected, a “Communication Timeout error” will occur if the TLB exception handler does not operate correctly. When [TLB miss exception is disable] is selected, the program does not jump to the TLB exception handler even if a TLB exception occurs. Therefore, if the TLB exception handler does not operate correctly, a “Communication

Timeout error” will not occur but the memory contents may not be correctly displayed.

12. Loading Sessions

Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading sessions. Thus the TCK value will be 5 MHz.

13. [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 2.3 Watchdog Timer Register

Register Name

WTCSR(W)

Usage

Write

Register

Watchdog timer control/status register

WTCSR(R) Read Watchdog timer control/status register

⎯ 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. 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

(SH7781.IO) and then activate the HEW. After the I/O-register definition file is created, the MPU’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/Oregister definition file according to the description in the hardware manual. The I/Oregister definition file can be customized depending on its format. Note that, however, the

E200F emulator does not support the bit-field function.

REJ10J1422-0200

Section 2 Software Specifications when Using the SH7781

⎯ Verify

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

14. Illegal Instructions

If illegal instructions are executed by STEP-type commands, the emulator cannot go to the next program counter.

15. [Reset CPU] and [Reset Go] in the [Debug] Menu

When a reset is issued from [Reset CPU] or [Reset Go] in the [Debug] menu, the clock pulse generator or system controller is not initialized.

2.2 Specific Functions for the Emulator when Using the SH7781

In the SH7781, a reset must be input when the emulator is activated.

2.2.1 Notes on Using the Trace Functions

The emulator supports the trace functions listed in table 2.4.

Table 2.4 Trace Functions

Function Internal Trace AUD Trace

Memory Output

Trace

Branch trace Supported (eight branches) Supported Supported

Range memory access trace Supported (eight events)

Software trace

Supported Supported

Supported (eight events) Supported Supported

Internal Trace Function: This function is activated by selecting the [Internal trace] radio button in the [Trace type] group box of the [Trace mode] page. Set the trace condition to be used.

Notes: 1. If an interrupt is generated at the program execution start or end, including a step operation, the emulator address may be acquired. In such a case, the following message will be displayed. Ignore this address because it is not a user program address.

*** EML ***

2. If a completion-type exception occurs during exception branch acquisition, the next address to the address in which an exception occurs is acquired.

3. Trace information cannot be acquired for the following branch instructions:

• The BF and BT instructions whose displacement value is 0

• Branch to H'A0000000 by reset

AUD Trace Function: This function is operational when the AUD pin of the device is connected to the emulator. It is activated by selecting the [AUD trace] radio button in the [Trace type] group box of the [Trace mode] page.

Notes: 1. When the trace display is performed during user program execution, the mnemonics, operands, or source is not displayed.

2. The AUD branch 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

Rev. 2.00 Jan. 28, 2008 Page 14 of 32

REJ10J1422-0200

Section 2 Software Specifications when Using the SH7781 addresses. If the previously output 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. In the emulator, when multiple loops are performed to reduce the number of AUD trace displays, only the IP counts up.

5. In the emulator, the maximum number of trace displays is 524288 lines. However, the maximum number of trace displays differs according to the AUD trace information to be output. Therefore, the above pointers cannot be always acquired.

6. The AUD trace acquisition is not available when [User] is selected in the [UBC mode] list box of the [Configuration] dialog box. In this case, close the [Trace] window.

7. If a completion-type exception occurs during exception branch acquisition, the next address to the address in which an exception occurs is acquired.

Memory Output Trace Functions: This function is activated by selecting the [Use Memory trace] radio button in the [Trace type] group box of the [Trace mode] page.

In this function, write the trace data in the specified user memory range.

Specify the start address to output a trace for the [Start] edit box in the [User memory area] group box, and the end address for the [End Address] edit box.

Notes: 1. The memory range for which trace is output is the address on the system bus and not supported for the MMU or cache.

2. In the memory range for output, do not specify the ranges that the user program has been downloaded or the user program accesses.

3. The range for trace output must be 1 MB or less.

2.2.2 Notes on Using the JTAG (H-UDI) Clock (TCK) and AUD Clock (AUDCK)

1. Set the JTAG clock (TCK) frequency to lower than the frequency of the SH7781 peripheral module clock (CKP).

2. Set the AUD clock (AUDCK) frequency to 100 MHz or lower. If the frequency is higher than

100 MHz, the emulator will not operate normally.

3. The set value of the JTAG clock (TCK) is initialized by executing [Reset CPU] or [Reset Go].

REJ10J1422-0200

Section 2 Software Specifications when Using the SH7781

2.2.3 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.

Accordingly, it can be set only to the internal RAM area. However, a BREAKPOINT cannot be set to the following addresses:

⎯ ROM areas in CS0 to CS6

⎯ Areas other than CS0 to CS6

⎯ Areas other than the internal RAM

⎯ A slot instruction of a delayed branch instruction

⎯ An area that can be only read by MMU

3. During step operation, BREAKPOINTs are disabled.

4. When execution resumes from the address where a BREAKPOINT is specified, single-step operation is performed at the address and execution is continued from the next PC value.

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. 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.

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 SH7781 MMU status during command input when the VPMAP_SET command setting is disabled. The ASID value of the SH7781 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 SH7781 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.

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 SH7781 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 [Output] window is

ILLEGAL INSTRUCTION, not BREAKPOINT.

Rev. 2.00 Jan. 28, 2008 Page 16 of 32

REJ10J1422-0200

Section 2 Software Specifications when Using the SH7781

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 SH7781 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 [Output] window is ILLEGAL INSTRUCTION, not BREAKPOINT.

11. If an address of a BREAKPOINT cannot be correctly set in the ROM or flash memory area, a mark z 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 z disappears.

2.2.4 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.

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; execution stops before the branch destination instruction.

2.2.5 Note on Setting the UBC_MODE Command

In the [Configuration] dialog box, if [User] is set while the [UBC mode] list box has been set,

Ch10 (IA_OA_R) and Ch11 (OA_OA_CT_R) of Event Condition cannot be used.

2.2.6 Note on Setting the PPC_MODE Command

In the [Configuration] dialog box, if [User] is set while the [PPC mode] list box has been set, Ch1 and Ch2 of the performance analysis function and options 1 and 2 of the profile function cannot be used.

Section 3 Preparing to Connect the Trace Unit

3.2.6 Layout of the Trace Unit Connector

When designing the user system, there are restrictions on the position to install the trace unit connector. Figure 3.4 shows the external dimensions of the trace unit.

The size of the printed-circuit board of the E200F trace unit is 90 mm

× 125 mm. The size of components around the user system connector must not exceed the limit on component installation

(the height must be 10 mm or less).

Section 3 Preparing to Connect the Trace Unit

Notes: 1. The external bus trace interface connector installed on the user system must be as close to the MPU as possible.

2. Wiring pattern of clock lines (CLKOUT)

The followings are notes on wiring of clock lines for the E200F trace interface signals.

Take them into consideration when designing the user system to embed suitable clock lines.

(a) Clock lines must be as short as possible.

(b) Clock lines must be surrounded by the GND pattern for protection so that the signals will be of low-impedance.

(c) Other layers next to the layer with clock line wiring should have solid patterns of GND/VCC so that the signals will be of low-impedance.

(d) To prevent affect by the crosstalk noise, other signal patterns must not be embedded along with the clock lines.

3.2.7 Restrictions on Using the Trace Unit

(1) This trace unit supports the external bus memory interfaces of SH7781; SRAM interface and byte-selection SRAM interface (except for SRAM page mode). For other memory interfaces

(burst ROM, MPX, DDR-SDRAM, PCI, and PCMCIA), bus trace acquisition and bus event detection are not supported.

(2) When the sequential trace stop condition or delay-count trace stop condition is specified, trace acquisition will stop after several cycles have been passed from the stop condition match cycle.

(3) During break mode, a timestamp value of the external bus trace information that has been acquired by a trace is not counted up.

(4) When an emulation memory is used, it is not possible to access the memory on the user system which is in the same area as an area where the emulation memory has been set.

(5) When an emulation memory is accessed, at least six wait cycles are required. Set the number of wait cycles by using bits WR3 to WR0 in the CS0 area wait control register (CS0WCR).

(6) When an emulation memory is used, set the same bus width (8 bits, 16 bits, or 32 bits) as that of the CS0 area on the user system. If the different bus width is set, the emulation memory will be illegally accessed.

(7) The emulator occupies the CS0 area where the emulation memory has been set. Accordingly, it is not possible to access the memory in the user system side of that area.

(8) This trace unit is available for the external 8-, 16-, or 32-bit data bus width. When the data bus width is 8 or 16 bits, unused data bus pins D31 to D8 (for 8-bit bus width) or D31 to D16 (for

16-bit bus width) of the trace unit connector must be fixed to high or low level. In addition, when area 0 is used with the emulation memory, the bus width of the emulation memory needs

SH4AL-DSP E200F Emulator User's Manual.

3.2.8 Description of Emulation Memory Control Signal

When the CS signal of the MPU is connected directly to the memory or used to generate the CS signal of the memory, connect the EM0OUT-N signal (pin 173) of the external bus connector instead of the CS signal of the MPU.

Even if the emulator is not used, prepare the jumper pins as shown in figure 3.5 so that connection of the CS signal can be easily changed.
