STM32 internal eeprom

I am working with a STM32L053 MCU. I would like to write to the internal eeprom, and based on the datasheet it takes 3.2 ms.

I have doubts that during that time interrupts will be ignored. It is not clear for me why. 

I thought that the code is in the flash and the eeprom is independent from the flash. 

(Or maybe this EEPROM is not a real EEPROM, but emulated EEPROM in flash?)

I can suggest the recommendation of AN4808 for STM32L0.

And firmware packege X-CUBE-NVMRWW.

Best regards,
