Configuration Register
The Configuration Register is used to control key operational modes and settings of the device
such as the One-Shot Mode, the temperature conversion resolution, the Fault Tolerance Queue,
the ALERT pin polarity, the Alarm Thermostat Mode, and the Shutdown Mode. The Configuration
Register is a 16-bit wide read/write register; however, only the first 8-bits of the register are
actually used while the least-significant 8-bits are reserved for future use to provide an upward
migration path to other temperature sensor devices that have enhanced features. Since only the
most-significant 8-bits of the Configuration Register are used, the device is backwards compatible
to industry standard LM75-type temperature sensors that use 8-bit wide registers.
After device power-up or reset, the contents of the most-significant byte (bits 15 through 8) of the
Nonvolatile Configuration Register will always be automatically copied into the Configuration
Register. Therefore, the Configuration Register settings will match the settings of the Nonvolatile
Configuration Register prior to when the device was powered-down or reset.
Since the
Configuration Register value will always be copied from the Nonvolatile Configuration Register,
the Configuration Register can be temporarily changed without affecting subsequent power-
up/reset settings. If it is desired for the new Configuration Register settings to become the new
power-up/reset settings, then the contents of the Configuration Register can be copied into the
most-significant byte of the Nonvolatile Configuration Register by using the Copy Volatile
Registers to Nonvolatile Registers command (see Copy Volatile Registers to Nonvolatile
Registers section on page 36).
Please note that when using the Copy Volatile Registers to
Nonvolatile Registers command, the contents of the THIGH and TLOW Limit Registers will also be
copied into the Nonvolatile THIGH and TLOW Limit Registers.
