Memory Protection Strategy
The XC866 memory protection strategy includes:
Read-out protection: The Flash Memory can be enabled for read-out protection and
ROM memory is always protected.
Program and erase protection: The Flash memory in all devices can be enabled for
program and erase protection.
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 4.
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 5 and Table 6, and the programmed password is erased. The Flash protection is
then disabled upon the next reset.
For XC866-2FR and XC866-4FR devices:
The selection of protection type is summarized in Table 5.
