I would like to use the MCF52252 for a new project. I need the ability to secure the flash memory, in order that it is not possible to read the flash (BDM access disable), and the only accepted function is a mass erase (via backdoor access or Ezport access). When i click on the "i" icon, in the "freescale buy" page, i see the following page (see attached picture). I am a bit confused with the mention "without security".
Can somebody tell me the meaning of "without security" ?
Does this means it is possible to secure the flash of only some MCF5225x devices (not all) ?
