CHAPTER2 Dependence Functions

2.4.6.3 Data Break

This function suspends program execution when data access (read/write) is made to a

specified address.

■Data Break

This function suspends program execution when data access (read/write) is made to a specified address. Up

to 8 points can be set.

When the data break occurs, the following message appears in the status bar.

Break at address by data event break

■How to set

Control the data break in the following methods:

• Dialog

- "Data" tab in the breakpoint setting dialog

For details, refer to "4.6.4 Breakpoints" in "SOFTUNE Workbench Operation Manual".

• Command

- SET DATABREAK

For details, refer to "3.9 SET DATABREAK (type 2)" in "SOFTUNE Workbench Command Reference

Manual".

Notes:

• A data break shares points with the following functions. The maximum number of data breaks

varies depending on how those functions are used.

- Code break

- Data watch break

- Trace trigger

- Sequencer

• The data break may stop after a few steps of instructions following the instruction with detection

access are executed.
