+### `settings.crc`
+
+> Returns the actual, and the expected checksum of the settings.
+
+### `settings.valid?`
+
+> Returns either `true` or `false`, depending on whether the sealed settings are

+
+### `settings.version`
+
+> Returns the (user-set) version of the settings.
+
+### `eeprom.contents`
+
+> Without argument, displays the full contents of the `EEPROM`, including the

+> With arguments, the command updates as much of the `EEPROM` as arguments are

+### `eeprom.free`

+> Returns the amount of free bytes in `EEPROM`.
