Hi

I want to  use the Data flash for my information's , i correctly write and read on this section

but my problem is when i want to write again on the same address i should erase all block but i have other information on that block .

i read the

 (32-bit MCU family built on the embedded Power Architecture.pdf )(RM0017.pdf)

in page 701 on EEPROM Emulation Section Wrote:

The choosen ECC algorithm allows some bit manipulations so that a Double Word can be

rewritten several times without needing an erase of the sector.

how can i do this without erasing hole block and what can i do for this ?

Thanks,

Best Regards

Vanima
