Renesas RA4M1 interrupt vector table

AlexA

The newer Arduino Uno R4 WiFi uses Renesas RA4M1. For starters, I am looking for the interrupts vector table for the RA4M1, but also I am looking for references that explain (hopefully in simpler terms and in detail) how I can implement interrupts when working with this chip. Thanks for any feedback. AA

    Hi Alex,

    Thank you for reaching out to Renesas! I would like to learn more about which ide are you using?

    Kind regards,

    The Renesas RA4M1 is a powerful microcontroller, and working with its interrupt system can be quite rewarding once you get the hang of it. Here's how you can get started:

    1. Interrupt Vector Table
    The interrupt vector table for the RA4M1 is detailed in its datasheet. You can find the RA4M1 Group Datasheet on Renesas' official site. This document includes the interrupt vector table and descriptions of each interrupt source.

    The table will list the interrupt numbers, their corresponding vector addresses, and the events they are associated with.

    2. Implementing Interrupts
    Understanding the ICU (Interrupt Controller Unit): The RA4M1 uses an Interrupt Controller Unit (ICU) to manage interrupt requests. The ICU links event signals to the NVIC (Nested Vectored Interrupt Controller) or other modules like the DMA.

    Setting Up an Interrupt:

    Identify the peripheral or event you want to trigger the interrupt.

    Configure the interrupt priority and enable it in the NVIC.

    Write an Interrupt Service Routine (ISR) to handle the interrupt event.

    Simplified References:

    The Renesas Community Forum has discussions and examples on implementing interrupts for the RA4M1.

    You can also explore this RA Family Callback Implementation Guide for insights into using callbacks with interrupts.

    3. Additional Resources
    The EK-RA4M1 User's Manual provides practical examples and configurations for working with the RA4M1.

    If you're new to Renesas microcontrollers, their FSP (Flexible Software Package) is a great tool to simplify development, including interrupt handling.

    Edna,

    I came across this thread and I have an issue correctly using interrupts. When you say "Configure the interrupt priority and enable it in the NVIC.", there is no information regarding that in the Renesas manual. I am unable to find the information in the ARM reference as well.
