Safety - Periodic interrupt - MPC5777C

[kerem0101]

Hello NXP Support!

I have 4 periodic interrupts. I want to measure these interrupts with SWT and if their periods are not suitable, my SWT setting will reset the system.

Is it possible to use only one SWT to measure all these interrupts? (eg using SWT_0)

Hello,

Hmm, I dont think this is the correct approach and it is also not possible to achieve by SWT.

For such purpose use one of the times which device offer. Or simply switch state of some pin in interrupt routine and measure it via oscilloscope.

Best regards,

Peter
