Password Entry. There are two passwords for the DS1865. Each password is 4 bytes long. The lower level password (PW1) will
have access to all unprotected areas plus those made available with PW1. The higher level password (PW2) will have all the
access of PW1 plus those made available with PW2. The values of the passwords reside in EEPROM inside of PW2 memory. At
power-up, all PWE bits are set to 1. All reads at this location are 0.
