How to handle divide by zero exception in FPU

Hi All,

I'm working on S32k358 .I see the exception bit is set in the FPSCR for division by zero exception but i don't see any exception handler is being triggered on that. I could see the vdiv.f32 instruction.

Thank you

Hi, It apparently should not trigger an exception, it is rather expected to test status register after operation.

Hi,
Is there any sample code to return value from the divide by zero operation upon checking the status register. Please share

Thanks

Unfortunately I don't have example code to share. I is just needed to test FPSCR register after operation.
