DS1683
Total-Elapsed-Time and Event Recorder with Alarm

Maxim Integrated
If the Password Value has been changed from the factory
default setting, the user has to enter this new password
value into the PWE registers after a power cycle in order
to unlock the memory again.
See Figure 3 for examples of writing the 4-byte Password
Value and the 4-byte Password Entry value.
User Memory
The DS1683 has 16 bytes of user-programmable,
EEPROM memory. User memory is set to read-only if
the correct password is not entered into the Password
Entry Bytes. If the correct password is entered into the
Password Entry Bytes, the data can be written to the User
Memory and stored in EEPROM with the correct I2C write
command.

1) ALL BYTES ARE SENT MOST SIGNIFICANT BIT FIRST.
2) THE FIRST BYTE SENT AFTER A START CONDITION
IS ALWAYS THE SLAVE ADDRESS FOLLOWED BY THE
