(d) Extension setting of the performance-result storing counter
The 32-bit counter stores the result of performance, and two counters can be used as a 64-bit
counter.
To set a 64-bit counter, check the [Enable] check box in the [Extend counter] group box of the
[Performance Analysis] dialog box for Ch1 and Ch3.
2. Displaying the result of performance
The result of performance is displayed in the [Performance Analysis] window or the
PERFORMANCE_ANALYSIS command in hexadecimal (32 bits).
However, when the extension counter is enabled, it is displayed in hexadecimal (64 bits).
Note: If a performance counter overflows as a result of measurement, “*” will be displayed for
upper bits.
3. Initializing the measured result
To initialize the measured result, select [Initialize] from the popup menu in the [Performance
Analysis] window or specify INIT with the PERFORMANCE_ANALYSIS command.
