BSL mode 6, which is used for enabling Flash protection, can also be used for disabling
Flash protection. Here, the programmed password must be provided by the user. To
disable the flash protection, a password match is required. A password match triggers
an automatic erase of the protected P-Flash and D-Flash contents, including the
programmed password. With a valid password, the Flash hardware protection is then
enabled or disabled upon next reset. For the other protection strategies, no reset is
necessary.
Although no protection scheme can be considered infallible, the XC878 memory
protection strategy provides a very high level of protection for a general purpose
microcontroller.
Note: If ROM read-out protection is enabled, only read instructions in the ROM memory
can target the ROM contents.
