Control By Sequencer - Fujitsu SOFTUNE F2 MC-16 User Manual

CHAPTER 2 DEPENDENCE FUNCTIONS
2.5.5

Control by Sequencer

This emulator has a sequencer to control events. By using this sequencer, sampling of
breaks or traces can be controlled while monitoring program flow (sequence). A break
caused by this function is called a sequential break.
■ Control by Sequencer
As shown in Table 2.5-2, controls can be made at 8 different levels.
One event can be set for one level.
The sequencer can perform shift from any level to any level, and the restart conditions can also be specified.

■ Setting Events
The emulator can monitor the MCU bus operation, and generate a trigger for a sequencer at a specified
condition. This function is called an event.
In the event, code (/CODE) and data access (/READ/WRITE) can be specified.
Up to eight events can be set. However, since hardware is shared with trace triggers, the actual numbers is
calculated as follows.
Current maximum constant of events =
8 - (current number of break settings + current number of trace trigger settings)
Table 2.5-3 shows the conditions that can be set for events.
