5.12.1 Measuring Data Coverage
The code coverage, data coverage and realtime profiling functions of the E100 emulator are mutually exclusive.
To use the data coverage function, choose Data coverage in the Switching function section on the System page of the
Configuration properties dialog box.
Data coverage indicates the kinds of access to data areas. The emulator is capable of acquiring information on access per byte
without causing program execution to break. Therefore, the realtime characteristic of user-program execution will not be
affected.
The coverage results are updated upon a break.
The E100 emulator comes with 512 Kbytes of data coverage memory.
With the initial settings, the data coverage memory is automatically allocated to addresses in the ROM and RAM areas, in that
order.
5.12.2 Opening the Data Coverage Window
Choose Code -> Data Coverage from the View menu or click on the Data Coverage toolbar button [ ].
The Data Coverage window is initially empty.
