Additional tools<br />

'History' function<br />

The History function is a great help after a system error. It may happen that<br />

you program a situation, which makes it impossible for the PCD to react on it.<br />

Example: You have signal on the interrupt input but no exception block,<br />

which handles the signal.<br />

The fact that there is an entry in the history doesn’t necessarily mean that there<br />

is a problem. Read the help for more information.<br />

After clicking on "History" in the main window, the following dialog box appears:<br />

Very last<br />

error<br />

The 4 most<br />

common<br />

messages<br />

The history table is displayed for the chosen CPU in the connected PCD.<br />

With one click on the "Clear history" button, this memory can be deleted.<br />

'Password' function<br />

This is basically the same function as the “Password” setting in the Hardware-<br />

Configurator, but online.<br />
