Sheet name Description

Address Range sheet Measurement is performed on any address range.

Section sheet Measurement is performed on a specified section.

Task Stack sheet Measurement is made of all task stack areas.

The respective sheets permit multiple ranges to be registered.

The Task Stack sheet supports only automatic registration.

Up to three instances of the Data Coverage window can be opened at the same time.

5.12.3 Allocating Data Coverage Memory (Hardware Resource)

(1) Memory allocation

Before data coverage can be measured, data coverage memory must be allocated to the addresses at which to be measured.

Coverage data can be obtained from only the address range that has had memory allocated.

To allocate data coverage memory, use the Allocation of Data Coverage Memory dialog box. To open it, choose Hardware

Settings from the context menu of the Data Coverage window.

Figure 5.104 Allocation of Data Coverage Memory dialog box

The emulator permits any of 1–8 blocks (maximum 512 Kbytes) each beginning with the 64-Kbyte boundary to be specified as

a data coverage measurement area.

Contiguous blocks or noncontiguous blocks, either one, can be set.

With initial settings, the coverage memory is allocated to addresses in the ROM and RAM areas.
