How to read/write flash memory instead of EEPROM

[MT.2]

Hi there!

I am using stm8s MCU for my application. As the number of data that I want to save is more than the size of EEPROM, is it possible to read/write data on flash memory? If yes, may I know how to make it works and how to allocate flash memory page/stack so that there will not be any crash between data memory and program memory.

Cheers,

Morris
