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

Table 2.11 Performance Measurement Conditions to be Counted

Measurement Condition

Notes

No caching due to the
settings of TLB cacheable
bit

Counted for accessing the cacheable area.

Cache-on counting

Accessing the non-cacheable area is counted less than the actual
number of cycles and counts. Accessing the cacheable, X/Y-RAM,
and U-RAM 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 hexadecimal (32 bits).
