Flash Protection Without hardware

program
D-Flash erase
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. A
password match triggers an automatic erase of the protected P-Flash and D-Flash
contents, including the programmed password. The Flash protection is then disabled
upon the next reset.
For the ROM device, the ROM is protected at all times and BSL mode 6 is used only to
block external access to the device. However, unlike the Flash device, it is not possible
to disable the memory protection of the ROM device. Here, entering BSL mode 6 will
result in a protection error.
Note: If ROM read-out protection is enabled, only read instructions in the ROM memory
Although no protection scheme can be considered infallible, the XC886/888 memory
protection strategy provides a very high level of protection for a general purpose
microcontroller.
