S12X Flash write access

I implemented the flash routines for the S12 and it works fine.


Now I have a new project with HCS12XEP and have to adapt the flash routines. Is it correct that I can write to a flash block while code fetching from a different flash block? Or is it the same like S12 (flash routines in RAM and no IRQ while flash access)? I didn't find an answer in the datasheet.
