Hi,

I've one question about erase and program Flash. When I erased one sector(1K) on FLASH, but I didn't program one sector and just program 8 bytes. If I read those non-program data, it will return what data? keep data before erased or can't be read?

If the answer is it can't be read. That's mean that if I want to write only 8 bytes data to FLASH, I still need to erase one sector and program one sector. Or the non-program part can't be read. Is it right?

 

Regards,

Pogo
