S32K Trigger Interrupt via Software

Jeniffer — Tue, 17 Jan 2023 07:22:08 GMT

Hello All,

I am using S32K116 micro controller. I am using Cortex M0. I am looking in to documentation and can not find how to: trigger interrupt via software

I want trigger interrupt handler function but there is not NVIC register for this work.

For example, can I trigger the LPSPI0_IRQHandlerfunction on my own request? or LPUART0_RxTx_IRQHandler.

Cortex M4 has NVIC->STIR and SCB->CCR for that.

SCB->CCR - USERSETMPEND[1:1]: Controls unprivileged access to STIR. Should be 1 to trigger interrupt in unprivileged mode.
NVIC->STIR - INTID[8:0]: Triggers the interrupt of the written IRQ number.

Hi Jeniffer,

The core of S32K11x is ARM Cortex M0+, so have a look at NVIC_ISPR in Cortex-M0+ Devices Generic User Guide.

Best Regards,
Robin
