3.6.22 Operational amplifiers (OPAMP)
Table 86. AMP_SM_0
SM CODE AMP_SM_0
Description Periodic read-back of OPAMP configuration registers
Ownership End user
Detailed implementation
This method must be applied to OPAMP configuration registers.
Detailed information on the implementation of this method can be found in
Section 3.6.14 Extended interrupt and events controller (EXTI) .
Error reporting Refer to NVIC_SM_0
Fault detection time Refer to NVIC_SM_0
Addressed fault model Refer to NVIC_SM_0
Dependency on Device configuration Refer to NVIC_SM_0
Initialization Refer to NVIC_SM_0
Periodicity Refer to NVIC_SM_0
Test for the diagnostic Refer to NVIC_SM_0
Multiple-fault protection Refer to NVIC_SM_0
Recommendations and known limitations Refer to NVIC_SM_0
Note: Because OPAMP modules are expected to be used in signal conditioning/amplification, their use in safety-
related functions lead to an application level scenario. End user is therefore responsible for the mitigation of
failure modes affecting the analog section of used OPAMP module(s).
3.6.23 Digital filter for sigma delta modulators (DFSDM)
Table 87. DFS_SM_0
SM CODE DFS_SM_0
Description Periodic read-back of DFSDM configuration registers
Ownership End user
Detailed implementation
This method must be applied to DFSDM configuration registers.
Detailed information on the implementation of this method can be found in
Section 3.6.14 Extended interrupt and events controller (EXTI) .
Error reporting Refer to NVIC_SM_0
Fault detection time Refer to NVIC_SM_0
Addressed fault model Refer to NVIC_SM_0
Dependency on Device configuration Refer to NVIC_SM_0
Initialization Refer to NVIC_SM_0
Periodicity Refer to NVIC_SM_0
Test for the diagnostic Refer to NVIC_SM_0
Multiple-fault protection Refer to NVIC_SM_0
