Store the data in EEPROM before or during the brownout detector

[Donatello]

Dear all,
I have some data that needs to be store in internal EEPROM during a voltage drop. In other microcontrollers (for example in PIC/dsPIC) it is possible store date through an interrupt that is activated when the voltage level drops below a threshold. In ESP32 I read that the brownout detector interrupt exists, but is it possible to write a function during the interrupt brownout to store the data?

Is there someone who can help me?
Thank you

Regards,
Donatello
