5.12 Measuring Data Coverage

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 Data Flash areas.

5.12.2 Opening the Data Coverage Window
