[Instruction Level] tab


The acquired trace data is searched at the instruction level.

Caution

If, while the Trace panel is displayed in the Source display mode, an instruction-level search is performed on this tab, the subject data cannot be searched correctly.
To perform an instruction-level search, make sure the Trace panel is displayed in the Mixed display mode or Disassemble display mode.

Trace Search Dialog Box: [Instruction Level] Tab

 

This section describes the following.

[How to open]

-

Click the toolbar button on the Trace panel.

-

Choose [Find] from the context menu on the Trace panel.

[Description of each area]

(1)

[Search condition] area

(a)

[Fetch Address]

Specify a fetch address, if needed as the search condition.

Enter an address expression directly in the text box or select an input history item from the drop-down list (up to 10 history entries).

The fetch address can also be specified as a range of addresses. In this case, enter address expressions in both the right and left text boxes to specify a range.

If the right-side text box is blank or labeled [(Input value when range is specified)], the fixed address specified in the left-side text box is used to perform a search.

Note that if any address value greater than the microcontroller's address space is specified, the high-order address value is masked when a search is performed.

Also, no address values can be specified that are greater than the value representable by 32 bits.

(b)

[Mnemonic]

Specify a character string of instruction, if needed as the search condition.

The character string specified here is searched from within the [Source/Disassemble] area of the Trace panel.

Enter an instruction directly in the text box or select an input history item from the drop-down list (up to 10 history entries).

Searches are case-insensitive, and partial matches are also allowed.

(c)

[Access Address]

Specify an access address, if needed as the search condition.

Enter an address expression directly in the text box or select an input history item from the drop-down list (up to 10 history entries).

The access address can also be specified as a range of addresses. In this case, enter address expressions in both the right and left text boxes to specify a range.

If the right-side text box is blank or labeled [(Input value when range is specified)], the fixed address specified in the left-side text box is used to perform a search.

Note that if any address value greater than the microcontroller's address space is specified, the high-order address value is masked when a search is performed.

Also, no address values can be specified that are greater than the value representable by 32 bits.

(d)

[Access Status]

This item is enabled only when [Access Address] is specified.

Select the type of access from the drop-down list below.

When not limiting the type of access, select [No Specification].

(No Specification)

Read/Write

Read

Write

Vector Read [Simulator]

DMA

Caution

[E1] [E20] [EZ Emulator]
The types of access for which data can be collected on the Trace panel are Read and Write. Therefore, do not select Read/Write, Vector Read or DMA from the drop-down list.
[Simulator]
The types of access for which data can be collected on the Trace panel are only Read, Write, and Vector Read. Therefore, do not select Read/Write or DMA from the drop-down list.


(e)

[Data]

This item is enabled only when [Access Address] is specified.

Specify an accessed numeric value.

Enter a hexadecimal value directly in the text box or select an input history item from the drop-down list (up to 10 history entries).

The numeric value can be specified as a range of values. In this case, enter data in both the right and left text boxes to specify a range.

If the right-side text box is blank or labeled [(Input value when range is specified)], the fixed numeric value specified in the left-side text box is used to perform a search.

(2)

[Search range] area

(a)

[Number]

Specify a range of trace data to search by numbers displayed in the [Number] area of the Trace panel.

Specify start and end numbers in the left and right text boxes, respectively. (By default, "0" to "last number" are specified.)

Enter a number in decimal notation directly in the text box or select an input history item from the drop-down list (up to 10 history entries).

If the left-side text box is blank, the number "0" is assumed.

If the right-side text box is blank, the "last number" is assumed.

[Function buttons]

Button

Function

Search Backward

Performs a search in the direction toward smaller addresses within a specified range.

The searched spot is put in selected state on the Trace panel.

However, if an invalid value is specified, a message is displayed and a search of trace data is not performed. Also, if the Trace panel is hidden, or if focus is moved to this dialog box while focus was present on another panel, this button is disabled.

Search Forward

Performs a search in the direction toward larger addresses within a specified range.

The searched spot is put in selected state on the Trace panel.

However, if an invalid value is specified, a message is displayed and a search of trace data is not performed. Also, if the Trace panel is hidden, or if focus is moved to this dialog box while focus was present on another panel, this button is disabled.

Cancel

Nullifies the setting for a search of trace data and closes this dialog box.
