+@deffn Command {at91samd chip-erase}
+Issues a complete Flash erase via the Device Service Unit (DSU). This can be
+used to erase a chip back to its factory state and does not require the
+processor to be halted.
+@end deffn
+
+@deffn Command {at91samd set-security}
+Secures the Flash via the Set Security Bit (SSB) command. This prevents access
+to the Flash and can only be undone by using the chip-erase command which
+erases the Flash contents and turns off the security bit. Warning: at this
+time, openocd will not be able to communicate with a secured chip and it is
+therefore not possible to chip-erase it without using another tool.
