Edit Events dialog box

In this section:

The Edit Events dialog box is available from the Emulator menu.

EditEvents_RL78_01.png

Use this dialog box to define the events used by the emulator as breakpoint, trace, and sequencer events.

In real-time, the emulator compares the address, data, access type, and probe signals with the events that you have defined. When all defined conditions are true, the event is raised.

Each event is uniquely named and listed with its settings at the bottom of the Edit Events dialog box. In the list, the Usage column shows how the event is used, that is, as breakpoint, trace, timer, or sequencer event.

Requirements

Any supported hardware debugger system, but requires a device that supports events.

Name

To define a new event, enter the event name in the Name list box and choose the appropriate characteristics. Click Add.

To modify an existing event, choose the event from the Name list box, enter the new characteristics and click on one of the Modify, Remove, or Remove All buttons.

For each event you can specify the access type, address, data, and external probe.

Address

Select this check box to specify a single address for the event. Enter the address value in the Address field. Any access to the specified address with the specified condition, causes the event to be triggered.

Note

You can enter a label instead of an address value.

Access type

Select the access type that should trigger the event. Choose from:

Read/write

A read/write access.

Read

A read access.

Write

A write access.

OP fetch

An operation fetch access. An OP fetch event will break after execution.

Data

Select this check box to specify data for the event. Specify the data value, mask, and access size. Any access with data with the specified access size and mask, causes the event to be triggered.

To define a data value, enter the data value in the Value field and select the size—Byte or Word. You can choose to enter a mask in the Mask field. The bit pattern for the value with the applied mask is displayed in the Pattern field.

Modify

Modifies the selected event in the Name list box using the current settings in the dialog box.
