Hi,
Flash driver is provided in DAVE3 as FLASH002 App.
The app provides the APIs for different flash operation.

I had read the help of FLASH002 App, It's not provide the API for read data from flash/memory. By the way,how to write an 16bit data into flash where is not used for code?

You can read from the memory directly using pointer to the memory address.

No, it is not possible. The minimum size to write to flash is a page size which is 256bytes
And for your information, to erase the flash, you have to erase by sector (16Kbytes - 256kBytes depending on which sector you are erasing).
