S32K148 EEPROM Programming process

[gary_yang]

Dear Sir：

We are a third-party programmer manufacturer and want to program S32K148 EEPROM (0x14000000~0x14000FFF).

Can you provide programming documents (including programming steps, processes, commands... and other information) for our reference?

Thanks

Hi @gary_yang,

The main differences between writting to SRAM and FlexRAM (in EEE mode) are:

• The EEE can be written once EEERDY = 1, which is set either automatically after system reset exit (which inludes the copy-down process) or after the FTFC SetFlexRAM Function command.

• Any write to EEE clears the FTFC CCIF flag, and any subsequent write can take place only once CCIF is set again.

For more information, refer to AN11983 Using the S32K1xx EEPROM Functionality
