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.
Although no protection scheme can be considered infallible, the SAA-XC886 memory
protection strategy provides a very high level of protection for a general purpose
microcontroller.
