CHAPTER 2 DEPENDENCE FUNCTIONS
2.5.4.4 Sequential Break
A sequential break is a function to abort an executing program as event sequential
control, when the sequential conditions are established.
■ Sequential Break
It is a function to abort the program execution by the sequential control of the event, when the sequential
conditions are established. For details of the sequential control, refer to Section "2.5.5 Control by
Sequencer".
When a break occurs due to a sequential break, the following message is displayed.
Break at Address by sequential break (level = Level No.)
■ Types of Sequential Break
This debugger has the following two types of the sequential breaks.
● 8 level sequence
8 level sequence is set in the sequence window displayed in [View]-[Sequence] menu. This sequence has the
following features.
• Up to 8 levels can be set.
• Multiple level of the shift ahead can be set to one (shift ahead) event.
• The break or trace control (acquisition start/acquisition end) can be set when the sequencer is ended
(END). The break is selected at this time.
• The trace control (acquisition start/acquisition end) can be set at each event hit of the sequencer.
• The current sequence level shift state at break can be displayed.
● 3 level sequence
3 level sequence is set in the 3 level sequence setting dialog displayed in [Debug]-[3 level sequence] menu.
For details, refer to section "4.6.6 Sequence" in "SOFTUNE Workbench Operation Manual".
• Up to 3 levels can be set.
• One level of the shift ahead can be set to one (shift ahead) event.
• The break or trace control (acquisition start/acquisition end) can be set when the sequencer is ended
(END). The break is selected at this time.
• When 3 level sequence is displayed in the sequence window, the current sequence level shift state at break
can be displayed.
Note:
The last level number of the sequencer is always 7. Therefore, if the level number of the message
displayed in the status bar at the sequential break is either 8 or 3 level, 7 is displayed in the last level
number of the sequencer.
