PMC ISR HIGH/LOW detected - MCU module

Hello, i using RTD:S32K3_RTD_4_0_0_P20_D2403_ASR_REL_4_7_REV_0000_20240315

in Safety manual are information that On-chip low voltage detector (LVD) is enabled by default. I enabled HVD using tresos, i added ISR using autosar tool.
When i change input voltage on e.g V25 to 2.8V, ISR if of course called.
My questions is:
How i shall react on this ISR? becasue when code of ISR is executed register of event is cleared. 
Is possible to adding any callback  ?  in tresos this option is not allowed. Callback is allowed only for McuPmcNotification but 
"Function pointer to callback function.
This notification will be called by the driver before entering in Standby Mode, after the Lastmile Regulator is disabled.
This node is not supported on S32K312 derivatives
Note: Implementation Specific Parameter."
I dont using standby_mode.

FCCU have group for this NCF_4 but then ISR is called from PMC, event is not generated for FCCU.

Hello @Marekp,

There is a notification callback.
