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.
