[Debug Tool Settings] tab

To add or delete an I/O protection area, select the [Memory mappings] property and click on the [...] button that appears on the right to open the Memory Mapping dialog box. For details on how to change settings, refer to the section of the Memory Mapping dialog box.

This property displays only the number of memory areas.

Expanding the [Memory mappings] property will display the following sub-items.

-	[Memory type] Indicates the memory type of the corresponding area. Each memory type corresponds to the following areas.

On-chip ROM area	Program ROMNote 1 and data flashNote 2
On-chip RAM area	On-chip RAM
I/O registers area	Peripheral I/O register Divided into areas with different endians for display
External area(CS7/CS6/.../CS0)	External address space CS0 to CS7 are displayed separately
Other memory area	FCU-RAMNote 3, FCU firmwareNote 3, user boot
Reserved area	Areas other than those listed above
I/O protection area	Address range in an external area that is not read by the debugger. Register this area in the Memory Mapping dialog box.

Note 1.

If data in the on-chip flash ROM area is changed by means other than downloading (e.g. by manipulating it via the Memory panel or line assembling), the flash ROM reflects this change next time the user program is run.

Note 2.

If an attempt is made to reference data in erased data flash ROM, only undefined values are displayed due to the specifications of the microcontroller. If the debugger is used to write to the data flash ROM, on the other hand, data is written in 256-byte units. Written areas do not hold undefined values.

Note 3.

Do not use the debugger to write to FCU-RAM. The FCU firmware area also cannot be written by the debugger.

-	[Start address] Displays the starting address of the corresponding area.

-	[End address] Displays the ending address of the corresponding area.

-	[Access width[bits]] Displays the access width of the corresponding area. When [Memory type] Indicates the memory type of the corresponding area. Each memory type corresponds to the following areas. is an external area, the access width can only be changed when the debug tool is disconnected.

-	[Endian] Displays the endians of the external area and the I/O register area. When [Memory type] Indicates the memory type of the corresponding area. Each memory type corresponds to the following areas. is an external area, the endian can only be changed when the debug tool is disconnected.

Caution

Connecting to a debug tool (see "2.4.1 Connect the debug tool to CS+") will display details for each memory type.

(b)	[Verify on writing to memory]

Specify whether to perform a verify check when the memory value is initialized from the drop-down list.

Select [Yes] to perform verification after download or when values are changed in the Watch panel/ Memory panel.

(2)	[Access Memory While Running]

You can configure the memory access while executing a program in this category.

The settings of this category are required when using the real-time display update function. See "2.11.1.4 Displaying and changing memory contents during program execution" for details on the real-time display update function.

Figure 2.52

[Access Memory While Running] Category

(a)	[Access by stopping execution]

Specify from the drop-down list whether to allow access to the memory area while executing a program.

Select [Yes] to allow access ([No] is selected by default).

(b)	[Update the display during execution]

Specify whether to update the display in the Watch panel/Memory panel while executing a program.

Select [Yes] to update the display (default).

Caution

You cannot change this property while the program is in execution.

(c)	[Update interval[ms]]

This property is displayed only when the [Update the display during execution] property is set to [Yes].

Specify the interval in 100ms unit to update the contents in the Watch panel/Memory panel display while executing a program.

Directly enter the Integer number between 100 and 65500 (rounding up the fractions less than 100ms) ([500] is specified by default).

Note that if you've changed the specified value of the [Update the display during execution] property from [No] to [Yes], the previous set value is displayed in this property.

Caution

You cannot change this property while the program is in execution.

(3)	[Register]

In this category, make settings related to PC display in the Status bar during program execution.

Figure 2.53

[Register] Category

(a)	[PC display during the execution]

This property specifies whether the PC value is displayed in the Status bar during program execution.

When you select [No], the Status bar under execution will show "Running."

Caution 1.

You cannot change this property while the program is in execution.

Caution 2.

[RX100 Series]
This property is hidden because these microcontrollers do not support display of the PC value in the status bar during program execution.

(b)	[Display update interval for PC[ms]]

This property is displayed only when you've selected [Yes] in the [PC display during the execution] property.

During program execution, specify a PC display updating interval in the Status bar in 100 ms units.

Enter an integer directly in the range 100 to 65500 (with fractions below 100 ms rounded up). (By default, [500] is specified.)

Note that if you've changed the specified value of the [PC display during the execution] property from [No] to [Yes], the previous set value is displayed in this property.

Caution

You cannot change this property while the program is in execution.

(4)

[Break]

You can configure the break function in this category.

Figure 2.54

[Break] Category

(a)	[Type of breakpoints to be preferentially used]

Specify from the following drop-down list the type of preferential breakpoint to be used with a single click of the mouse in the Editor panel/Disassemble panel.

When setting a break point after the preferential break point type has been used up, the other break point type will be automatically selected.

See "2.10.2 Stop the program at the arbitrary position (breakpoint)" for details on breakpoints.

Software break	Sets software breakpoint preferentially.
Hardware break	Sets hardware breakpoint preferentially (default).
