Development Tools

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 RAMNote 4
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.

Note 4.

The area including the option setting memory areas listed below is displayed as an on-chip RAM area. Note that values cannot be specified in this area through the memory panel.

[RX71M, RX66x, RX65x, RX64M, and RX72T Groups]

Caution 1.

If you have selected [Real-time RAM Monitor] in [Usage of trace function] property, [Do not output] cannot be selected from the drop-down list.

Caution 2.

If Step in is executed when [CPU execution] or [Trace output] is specified and trace data is being displayed on the Trace panel, correct trace data may not always be displayed.

Caution 3.

Enter a count source with which a timestamp value is calculated from a count value.

To specify this, enter a value directly in the range 0.0001 to 999.999.

Note that if this property is blank, the set value of the [Operating frequency [MHz]] property in the [Clock] category of a [Connect Settings] tab is used in place of the count source.

Caution 1.

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

Caution 2.

The property's set value is not reflected in the trace data that has already been collected. The property you've set is reflected beginning with the trace data that is Division ratio of trace clock count source collected after it is set.
