Unlock Key

An 8-byte key that is used to prevent accidental changes to certain configuration values. For a factory-reset device this is all zeroes, otherwise it is the key stored in the currently active configuration’s volatile memory, which in turn is loaded from the configuration’s non-volatile storage when set.

New Unlock Key

An 8-byte key that will replace the current Unlock Key.

Notes

The Unlock Key value is used to prevent accidental changes to certain configuration items that may adversely affect the device functionality, such as pin assignments. The key is stored in the volatile memory (ie. RAM) and not persisted to non-volatile flash until a Store Current Configuration command is issued. This means that it is possible to issue a temporary key that will be forgotten once the device has been power-cycled or another configuration has been activated.
