For the first use, since the passwords actually stored in the device are unknown, the DS1991 needs to be
initialized. This is done by directly writing (i. e., not through the scratchpad) the new identifier and
password for the selected subkey using the Write Password command. As soon as the new identifier and
password are stored in the device, further updates should be done through the scratchpad.

* Each subkey or the scratchpad has its own unique address.
