Write Password [5AH]
The Write Password command is used to enter the ID and password of the selected subkey. This
command will erase all of the data stored in the secure area as well as overwriting the ID and password
fields with the new data. The DS1991 has a built-in check to ensure that the proper subkey was selected.
The sequence begins by reading the ID field of the selected subkey; the ID of the subkey to be changed is
then written into the part. If the IDs do not match, the sequence is terminated. Otherwise, the subkey
contents are erased and 64 bits of new ID data are written followed by a new 64-bit password. The
command sequence is shown in Figure 5, 2nd page, right column.
