Each measurement condition is also counted when conditions in table 2.11 are generated.

Notes
Cache-on counting
Accessing the non-cacheable area is counted less than the actual
number of cycles and counts. Accessing the cacheable and U
memory areas is counted more than the actual number of cycles
and counts.
Branch count
The counter value is incremented by 2. This means that two cycles
are valid for one branch.
Notes: 1. In the non-realtime trace mode of the AUD trace, normal counting cannot be performed
because the generation state of the stall or the execution cycle is changed.
2. Since the clock source of the counter is the CPU clock, counting also stops when the
clock halts in the sleep mode.
2. Displaying the measured result
The measured result is displayed in the [Performance Analysis] window or the
PERFORMANCE_ANALYSIS command with 32 bits.
Note: If a performance counter overflows as a result of measurement, “********” will be
displayed.
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.
