I need to test the ADC clock monitoring in TC297. The AURIX Safety Manual mentions test of ADC clock but I cannot find how to test. I have implemented tests for other clock monitors like STM, GTM and SystemPLL but there is no similar clock monitoring registers for ADC clock. What is the recommendation for TC297?

Hi mATHIAS,

If there is no clock monitor, SMU will not be notify as above described.

Hi MathiasS13,

For tc27x_um_v1.4.pdf, there is a clock monitor, below is fyi. If no this register, you could judge by the wrong data from ADC of a known input voltage.

Thanks for the reply.

There is an SMU alarm ALM3[9], Safety Mechanism: Clock Monitor
Alarm: ADC clock out of range frequency. Is it possible to trigger this alarm in TC297?
