SM CODE VSUP_SM_4
Error reporting Interrupt generation on specific EXTI lines
Fault detection time Depends on threshold programming, refer to functional documentation
Addressed fault model Permanent and Transient
Dependency on MCU configuration None
Initialization Protection enable and threshold programming on selected power rails in Power control register
Periodicity Continuous
Test for the diagnostic Not needed
Multiple faults protection CPU_SM_5: external watchdog
Recommendations and known limitations
This method can be used in conjunction with VSUP_SM_0 to implement a complete supervision of
VDD value
