Does anyone know about EEPROM emulation for S12ZVL?
There's some problem and limitation to use PFLASH as EEPROM.
I only could find the document for Qorriva, but there's no sample code or driver.

Thank you.

Hi,
I’m afraid there is no such driver for MagniV MCUs.
There are drivers for S12C32/S12XS/S12P MCUs which do not have EEPROM.
AN2302 EEPROM Emulation for the MC9S12C32
AN3961 EEPROM Emulation for the MC9S12XS and MC9S12P Families Using AN2302 as a Reference
You might use the drivers as a reference.
Unfortunately, that’s all we have.

Hi,
There is EEPROM (128 - 2048B) on S12ZVL.
Do you need to emulate additional EEPROM?

Hi Daniel.
I'm using 12ZVL32F that has 128byte EEPROM.
It's not enough space to satisfy our specification .
To satisfy our specification, I need additional space.
But, there's limitation to use PFLASH as EEPROM as you know.
I found this similar solution to another device Qorivva.

And, I want to know if there's driver and documentation for the MagniV about EEPROM emulation.
Thank you.
