STM8AL3189TCX out of regulation reset

Hi Team,

We are using STM8AL3189TCX in our design and have some general querries for diagnostic report preparation(Specific to project)

1) HOST MCU window Watchdog(TPS3850H33QDRCRQ1)

 If WDI pulse from HOST MCU fails this condition (Lower Boundary (tWDLmin) = 19.1ms-25.6ms & Upper Boundery (tWDUmax) = 46.8-63.3ms). Will the Supervisor asserted low to reset by MCU?

2) MCU Power supply Output - UV , OV Fault(+3V3_SYS - TPS7B6933QDCYRQ1)

Supervisor will be asserted low to reset, HOST MCU to turn off the system. Is the statement correct?

3) MCU ADC_VREF supply(LM4128BQ1MF2.5/NOPB) - Short circuit

What will happen to Host MCU? Will the MCU reset the whole system?

We want to understand if it is possible to diagnose the Host MCU output when Supervisor will be asserted low to reset?
