CHAPTER 2 DEPENDENCE FUNCTIONS
■ 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 trace trigger settings + current number of data monitoring break settings)
Table 2.3-5 shows the conditions that can be set for events.
Note:
In instruction execution (/CODE), an event trigger is generated only when an instruction is executed.
This cannot be specified concurrently with other status (/READ or /WRITE).
Use the following commands to set an event.
SET EVENT : Sets an event
SHOW EVENT : Displays the status of event setting
CANCEL EVENT : Deletes an event
[Example]
>SET EVENT/CODE func1
>SET EVENT/WRITE data[2],!d=h'10
>SET EVENT/READ/WRITE 102
