Description Periodic read-back of configuration registers
Ownership End user
Detailed implementation
This method must be applied to SPI configuration registers.
Detailed information on the implementation of this method can be found in
Section 3.6.14 Extended interrupt and events controller (EXTI).

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

Table 128. SPI_SM_1
SM CODE SPI_SM_1
Description Protocol error signals
Ownership ST
Detailed implementation
SPI communication module embeds protocol error checks (like overrun, underrun, timeout
and so on) conceived to detect network-related abnormal conditions. These mechanisms
are able anyway to detect a marginal percentage of hardware random failures affecting the
module itself.
Error reporting Error flag raise and optional interrupt event generation
Fault detection time
Depends on peripheral configuration (for example baud rate). Refer to functional
documentation.
Addressed fault model Permanent/transient
Dependency on Device configuration None
Initialization Depends on implementation
Periodicity Continuous
Test for the diagnostic Not applicable
Multiple-fault protection SPI_SM_2: Information redundancy techniques on messages
Recommendations and known limitations None
