LPC55S69 : minimal PRINCE write chunk

Hello !

I can see SDK example about encryption/description on fly to flash memory by using PRINCE engine.

/* Loading data into the PRINCE - controlled flash area.
Note, that following conditions must be met (otherwise the error is returned):
- whole PRINCE subregions (8k block) must be erased at once
- whole PRINCE subregions (8k block) must be loaded at once (no partial write allowed)

Do I understand right and 8KB is minimum size for write and erase ?

So it is not possible to erase 8KB at once and after that write 512 bytes sectors ?

Regards,

Eugene
