    Hi m123456

    There are 64KB program FRAM +0.5KB data FRAM in FR2476. you can use all unused program areas for data store.

    Please make sure the code area is write protection during code writing data to the FRAM.

    0.5KB Data (Information) FRAM write protection is SYSCFG0.DFWP

    Program FRAM write protection offset address, The offset increases by 1KB resolution is SYSCFG0.FRWPOA

    using these 2 types write protection function, you can store your data in FRAM and protect your code area at the same time.

    Thanks!
