Hi,
I am designing our custom board using S32K3 series controller. I have a query regarding the external gpio interrupts.
As per the S32K3x Reference manual: (SIUL2 which controls the GPIOs) the interrupts are supported only on pins that have EIRQn option. All GPIO pins do NOT support interrupts.
Is the above understanding correct?
Most modern controllers support interrupts on any GPIO pin. That makes me think my understanding of S32K3 gpio interrupt may be wrong.
Any inputs on the above will be of help.
Thanks in advance.
Hello,
Is the above understanding correct?
Yes, stick with IOMUX excel sheet to see which ones can be used for external interrupt.
Most modern controllers support interrupts on any GPIO pin. That makes me think my understanding of S32K3 gpio interrupt may be wrong.
Well, this will be based on use case of the chip. This one is ASIL-D automotive. I can imagine in industrial devices, it is possible.
Best regards,
Peter
