Hi,

I have a question about Safety Flips flops SMU.

According to Aurix TC3xx Safety Manual ,The test ESM[SW]:SMU:REG_MONITOR_TEST must be performed in Start-up phase.

My question Is:

Is it recommended to perform also this test in run time, in a cyclic task , every X ms ?

After SMU activation and lock, all SMU registers are write protected to prevent unwanted modifications during runtime. But the SFF test for SMU requires to write the SMU registers to activate/run a SFF test.. It would be needed to unlock the SMU temporarily to run a SFF test or to leave the SMU unlocked to allow these tests...

Hi,

Please contact the local sales/ FAE team since the safety topic needs an NDA and cannot be discussed in the public forum.

Best Regards.
