Initializing the Electronic Journal
Once the electronic journal is partitioned, it can be initialized. Initializing the electronic
journal sets the password and formats the flash to accept journal entries. Each entry
may be any length up to 8K. Entries greater than 8K are truncated. Entries will be added
to the electronic journal until it is full. If the electronic journal is full, entries will be lost.
The [ENQ]<25> command can be used to query the state of the electronic journal.
