3.2.1
The XC864 memory protection strategy includes:
• Read-out protection: The user is able to protect the contents in the Flash memory from
• Flash program and erase protection: The Flash memory in all devices can be enabled
• Block external access and allow only boot in User Mode: Disable BSL and OCDS
Flash memory protection modes provided are:
• Mode 0: Protect against accidental erase and block external access.
• Mode 1: Read, program and erase protection are enabled, and block external access.
Flash protection is enabled by installing the user password via BSL mode 6. The user
setting of password for selection of each protection mode and the restrictions imposed
are summarized in
used for code only. Otherwise if the Flash is used partially for code and partially for data,
then only Flash protection mode 0 is meaningful.
Note: In XC864, the type of Flash protection scheme will affect the entering of BSL Mode
