S32K3 SW interrupt

ziomocci — Thu, 28 Jul 2022 09:50:54 GMT

Hi all,

we are migrating from NXP PPC technology to NXP ARM; with PPC, we used the SW interrupt sources.

We are not finding same IRQs in S32K3 Reference Manual.

Does it exist anything similar to be used with ARM uContollers?

Best Regards,

Andrea

Hi Andrea,

take a look at this ARM feature:

Hi Lukas,

Thanks for your reply; I will take a look to the core specification in the next days.

Anyway, in the online documentation I read

but the mentioned field USERSETMPEND is part of Configuration and Control Register (CCR) and not of the System Control Register (SCR), as descirbed in the Core spec

Thanks for your support, I will send you a feedback in the future.

Regards,

Andrea
