There are two passwords for the DS1875. Each password is 4 bytes long. The lower level password (PW1) has all the
access of a normal user plus those made available with PW1. The higher level password (PW2) has all the access of
PW1 plus those made available with PW2. The values of the passwords reside in EEPROM inside PW2 memory. At
power-up, all PWE bits are set to 1. All reads at this location are 0.
