Interrupt execution time

mehmetkaradag — Mon, 15 May 2023 14:50:40 GMT

Hi, NXP engineers,

I am using mpc5777c.

Let's assume the execution time of the interrupt with the highest priority is 30us, and the interrupt with the lower priority as 10us.

when high priority interrupt interrupts low priority interrupt , execution time of lower priority interrupt is measured 70us. but it has to be 40us.

what could be the problem?

thanks for your help.

Could you specify used measuring method?
