Description
Provides control and configuration of various functions on the device.
Determines the number of measurements per second completed by the ADM1033.
Contains the address that selects one of the other internal registers. When writing to the ADM1033, the first byte
of data is always a register address, which is written to the address pointer register.
Provides the status of each limit comparison.
Allows the option to mask ALERTs due to particular out-of-limit conditions.
Stores the results of temperature and fan speed measurements, along with their limit values.
Allows the local and remote temperature channel readings to be offset by a twos complement value written to
them. These values are automatically added to the temperature values (or subtracted from them if negative). This
allows the systems designer to optimize the system, if required, by adding or subtracting up to 15.875°C from a
temperature reading.
Contains the temperature value at which THERM is asserted and determines the level of hysteresis.

Used to program the look-up table for the fan-speed-to-temperature profile.
Reflects the state of the THERM input and monitors the duration of the assertion time of the signal as a
percentage of a time window. The user can program the length of the time window.
