There are two passwords for the DS1884. Each password is 4 bytes long. The lower level password (PW1) will have all the
access of a normal user plus those made available with PW1. The higher level password (PW2) will have all of 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.
POWER-ON VALUE
TBLSELPON (A2h Table 02h, Register C7h).

The upper memory tables of the DS1884 are accessible by writing the desired table value in this register. The power-on
value of this register is defined by the value written to TBLSELPON (A2h Table 02, Register C7h).
