Hardware Interrupt
Trigger function-call subsystems in response to hardware interrupt events
Since R2026a
Libraries:
Embedded Coder Support Package for Renesas RA Microcontrollers /
Renesas RA6 Based
Description
The Hardware Interrupt block triggers a downstream function-call subsystem from an interrupt service routine. When the selected interrupt occurs, the block outputs a signal that activates the connected function-call subsystem.
You can select the appropriate interrupt service routine and define which events to handle, as well as the order in which they are executed. Additionally, you can assign a priority level to the downstream function-call subsystem to control its execution precedence.
Examples
Using Analog to Digital Converter Block with Renesas RA Microcontrollers
Digitize analog signals on Renesas® RA microcontrollers using the Analog to Digital Converter (ADC) block in Simulink® with Embedded Coder® Support Package for Renesas RA Microcontrollers. In this example, you measure the on-chip temperature sensor on a Renesas MCK-RA6T2 board and convert raw ADC values into temperature readings.

Parameters
Select the peripheral group whose interrupt you want to use. The available options depend on the Renesas RA device and configuration.
Programmatic Use
Block Parameter:
ISRGroup
|
Specify the name of the callback function associated with the selected interrupt group.
Programmatic Use
Block Parameter:
ISRName
|
Select to specify a new callback function name derived from the current callback.
Programmatic Use
Block Parameter:
UseDerivedISRName
|
Specify the name for the derived callback function.
Dependencies
To enable this parameter, select the Derive current callback to new callback parameter.
Programmatic Use
Block Parameter:
DerivedISRName
|
Select one or more events to service from the selected interrupt group. You can also select the execution order for each event. This parameter allows you to manage which interrupt events the block will handle and in what order.
Execution Order: Each event listed under Events to serve parameter has an execution order. You can use the Execution order drop-down list to specify the priority in which each event should be handled. Lower numbers indicate higher priority; events with a lower execution order will be executed before those with a higher number.
Filter table contents: The Filter table contents field allows you to quickly search for specific events. You can type either the event name or the execution order into this field. As shown in the image, entering a keyword, for example:
ADC_1filters the list to only show events that match the search term.
Programmatic Use
Block Parameter:
EventsList
|
Specify the priority of the downstream function-call subsystem. Lower values indicate higher priority. This controls the execution precedence of the function-call subsystem triggered by the interrupt.
Programmatic Use
Block Parameter:
TaskPriority
|
Select to enable atomic execution of the interrupt service routine. When enabled, all other interrupts are blocked while the selected interrupt service routine is running.
Programmatic Use
Block Parameter:
DisablePreemption
