In AT90CAN64 Product, if the Bootloader and Application protection modes are pro-
grammed at level 3, the LPM instruction does not operate properly in some configuration
cases. It will not load the right constant value. The differents cases versus BOOTSIZE value
and Flash memory areas are detailed in following Tables :
