5.2 EEPROM Functions

To implement this functionality, 11 functions are required to configure, program, read, and erase in Page programming. Two additional functions are needed for 64-bit programming. All functions are included in the F28P65x_EEPROM.c or F28P65x_EEPROM_PingPong.c file.

  • EEPROM_Config_Check()
  • Configure_Protection_Masks(Uint16* Sector_Numbers, Uint16 Num_EEPROM_Sectors)
  • EEPROM_Write(Uint16* Write_Buffer)
  • EEPROM_Read(Uint16* Read_Buffer)
  • EEPROM_Erase( )
  • Erase_Bank( )
  • EEPROM_GetValidBank(Uint16 Read_Flag)
  • EEPROM_UpdateBankStatus( )
  • EEPROM_UpdatePageStatus( )
  • EEPROM_Get_64_Bit_Data_Address()
  • EEPROM_Program_64_Bits(Uint16 Num_Words)
  • EEPROM_CheckStatus(Fapi_StatusType* oReturnCheck);
  • ClearFSMStatus()

The description of each of these functions is discussed in detail in the subsequent sections.
