5.12.4 Measuring an Address Range

The E100 emulator shows the access information it collected from a user-specified address range.

Figure 5.107 Data Coverage window (address specification)

The Data Coverage window is vertically divided into halves by a splitter.
The upper area shows the address ranges to be measured and access rates.

Table 5.35 Contents in the upper area of Data Coverage window

[Range]

Address ranges in which coverage is measured

[Access Rate]

Shows access rates by a percentage and graph

The lower area shows detail information of the address range selected in the upper area.

Table 5.36 Contents in the lower area of Data Coverage window

[Address] Address

value

[Label] Label

name

[Area]

Memory area (FlashROM, RAM, SFR)
This column is blank for unused areas.

[Data] Memory

data

The accessed data has its background displayed in purple.

If located outside the coverage memory allocated area, address lines are displayed in gray. Although the existing coverage
information of those addresses is retained, updating of coverage information by program execution does not apply.
The acquired coverage information is accumulated in memory until the user clears it.
