3.6.22 Cyclic redundancy-check module (CRC)
Table 92. CRC_SM_0
SM CODE CRC_SM_0
Description CRC self-coverage
Ownership ST
Detailed implementation
The CRC algorithm implemented in this module (CRC-32 Ethernet polynomial: 0x4C11DB7) offers
excellent features in terms of error detection in the message. Therefore permanent and transient
faults affecting CRC computations are easily detected by any operations using the module to
recompute an expected signature
Error reporting Depends on implementation
Fault detection time Depends on implementation
Addressed fault model Permanent and Transient
Dependency on MCU configuration None
Initialization Depends on implementation
Periodicity Continuous
Test for the diagnostic Not needed
Multiple faults protection CPU_SM_0: periodical core self-test software
Recommendations and known limitations None
