That is a good point. The firmware probably ought to write protect the extra MMR areas at startup. Ideally, the `sys/mfg` package which reads the MMRs would do this automatically. This package can do this using the `hal_flash_write_protect()` function, but that is just software protection. I don't believe we have support for generic hardware-based protection. Chris
