ST STM32L4 Series User Manual

Table 32. FLASH_SM_9
SM CODE FLASH_SM_9
Description Periodic test by software for Flash memory address decoder
Ownership End user
Detailed implementation
Permanent faults affecting the system Flash memory interface address decoder are
addressed through a dedicated software test that checks the memory cells contents versus
the expected value.
Error reporting Depends on implementation
Fault detection time Depends on implementation
Addressed fault model Permanent
Dependency on Device configuration Flash memory size depends on part number.
Initialization Not required
Periodicity Periodic
Test for the diagnostic Not applicable
Multiple-fault protection CPU_SM_0: Periodic core self-test software
Recommendations and known limitations Overlaps with FLASH_SM_0 implementation are possible.
3.6.5 Firewall (FW)
Table 33. FWR_SM_0
SM CODE FWR_SM_0
Description Periodic read-back of Firewall configuration registers
Ownership End user
Detailed implementation
This method must be applied to Firewall configuration registers (also unused by End
userApplication software).
Detailed information on the implementation of this method can be found in
Section 3.6.14 Extended interrupt and events controller (EXTI).
