      Hi all,

      when are SMPU master/slave protection structures reset or cleared?

       

      My goal is to try to mimic Secure state and keep a chip in Normal state. I was thinking to setup SMPU to totally disable DAP master (It will not have any read/write/execute permission) and ensure that only PC 0 can enable DAP again. Is such thing possible?

       

      It looks that SMPU setting survives power cycle and only device reset from the PSoC Programmer software clears it.

       

      Regards
