The SAA-XC866 memory protection strategy includes:
• Read-out protection: The Flash Memory can be enabled for read-out protection and
• Program and erase protection: The Flash memory in all devices can be enabled for
Flash memory protection is available in two modes:
• Mode 0: Only the P-Flash is protected; the D-Flash is unprotected
• Mode 1: Both the P-Flash and D-Flash are protected
The selection of each protection mode and the restrictions imposed are summarized in
Table
Table 3
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 read-protected Flash contents, see
Table 4
then disabled upon the next reset.
