The section of the CPU RAM controlled by the Secure State is from address 0x00000000 to address (SS_ADRR << 10).
The section of the Flash controlled by the Secure State is from address 0x80000000 to address (SS_ADRF << 10).
0: The WDT is automatically enabled at startup, the WDTAUTO fuse of the WDT is set.
1: The WDT is not automatically enabled at startup, the WDTAUTO fuse of the watchdog timer is not set.
Please refer to the WDT chapter for detail about time-out settings when the WDT is automatically enabled.

The devices are shipped with the User page erased (all bits 1).
The USB/USART bootloader uses two words in the flash user page to store its configuration:
Please refer to the bootloader documentation for more information.
• Configuration word 1 at address 0x808001FC is read first at boot time to know if it should
• Configuration word 2 at address 0x808001F8 stores the I/O conditions that determine which
start the ISP process unconditionally and whether it should use the configuration word 2
where further configuration is stored.
