5. Debugging Functions
(1) Setting measurement conditions
The measurement mode can be selected from among the four choices listed in Table 5.24. Select one measurement mode for
one section. Use events to specify the beginning and end of a section. The value of Count is fixed to 1. The event count is
always 1, even if you have attempted to specify some other value.
Table 5.24 Measurement modes
[Disabled]
Measurement is disabled.
[Between two events]
Figure 5.68 Between two events
Measurement is performed between the start event and the end event.
Specifically, the time execution takes and number of passes through the range
between the start event and the end event are measured. The measurement of
time starts when the start event occurs and is suspended when the end event
occurs. The number of passes through the section is incremented by one each
time the pair of the start event and end event for the specified range occur.
Start event: One or multiple events can be set.
End event: One or multiple events can be set.
[Period of an event]
Figure 5.69 Period of an event
Measurement is performed during the event.
Namely, the period between occurrences of the event the number of times it
occurs are measured. The time from one occurrence of the event to the next is
measured as one instance. The number of times is incremented by one each
time the event occurs.
Event: Only one event point can be set.
