CHAPTER 2 DEPENDENCE FUNCTIONS
2.6.6.6 Sequencer
A sequencer is a function to abort the program execution to the specified event condition
when program passes the event following a certain flow (sequence).
■ Control by Sequencer
Table 2.6-2 shows the specifications of the sequencer function for this emulator debugger.
2 events are set and the level is passed through level 1 to level 2 in this order. This becomes sequencer
termination condition. This sequencer is called a 2-level sequencer.
Furthermore, pass information up to that point is reset and an event for restart which monitors the passage of
level 1 againg can be set.
■ Operation of Sequencer
When events are set to each level as shown in example, the sequencer operates as shown in Figure 2.6-4.
[Example]
Level 1 : Event 1
Level 2 : Event 2
Restart : Event 3
