CLKOUT is not working in s32k144

[KKumar]

Hi NXP,

I trying to use CLKOUT in s32k144. I wrote following code

After running for some time(3s)..execution is going to Default ISR.

Plz Support

Hi @KKumar,

This code can overwrite other bits in the CHIPCTL register, use this instead to clear just the CLKOUTSEL bits:

SIM->CHIPCTL &= ~SIM_CHIPCTL_CLKOUTSEL_MASK;

The Default_ISR() is probably a fault exception.

Can you debug it as explained here:
