+@deffn Command {kinetis fcf_source} [protection|write]
+Select what source is used when writing to a Flash Configuration Field.
+@option{protection} mode builds FCF content from protection bits previously
+set by 'flash protect' command.
+This mode is default. MCU is protected from unwanted locking by immediate
+writing FCF after erase of relevant sector.
+@option{write} mode enables direct write to FCF.
+Protection cannot be set by 'flash protect' command. FCF is written along
+with the rest of a flash image.
