Edit Interrupt dialog box

In this section:

What do you want to do?

YellowStripe.png

The Edit Interrupt dialog box is available from the Interrupt Setup dialog box.

EditInterruptDlg_01.png

Use this dialog box to interactively fine-tune the interrupt parameters. You can add the parameters and quickly test that the interrupt is generated according to your needs.

Note

You can only edit or remove non-forced interrupts.

Requirements

The C-SPY simulator.

Interrupt

Selects the interrupt that you want to edit. The drop-down list contains all available interrupts. Your selection will automatically update the Description box. The list is populated with entries from the device description file that you have selected.

Description

A description of the selected interrupt, if available. The description is retrieved from the selected device description file and consists of a string describing the vector address, default priority, enable bit, request bit, and priority bit, separated by space characters. For interrupts specified using the system macro __orderInterrupt, the Description box is empty.

First activation

Specify the value of the cycle counter after which the specified type of interrupt will be generated.

Repeat interval

Specify the periodicity of the interrupt in cycles.

Variance %

Selects a timing variation range, as a percentage of the repeat interval, in which the interrupt might occur for a period. For example, if the repeat interval is 100 and the variance 5%, the interrupt might occur anywhere between T=95 and T=105, to simulate a variation in the timing.

Hold time

Specify how long, in cycles, the interrupt remains pending until removed if it has not been processed. If you select Infinite, the corresponding pending bit will be set until the interrupt is acknowledged or removed.

Probability %

Selects the probability, in percent, that the interrupt will actually occur within the specified period.
