MB95F636 is dual flash memory type, it has upper bank (32KB) and lower bank (2x2K). The data of parameters can store into lower bank (0x1000~0x1FFF).You can get all the flash operation commands from CHAPTER 25 DUAL OPERATION FLASH MEMORY of MCU hardware manual document.

We also have 8FX simulate eeprom lib, it is very easy to implement this function.

Please contact with the local FAE/SALES to sign the NDA to get it.
