Table 5. INTERNAL REGISTER DESCRIPTIONS
Register
Description
Configuration
Provides control and configuration of various functions on the device.
Conversion Rate
Determines the number of measurements per second completed by the ADM1033.
Address Pointer
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, written to the address pointer register.
Status
Provides the status of each limit comparison.
Interrupt Mask
Allows the option to mask ALERT
s due to particular out-of-limit conditions.
Value and Limit
Stores the results of temperature and fan speed measurements, along with their limit values.
Offset
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癈 from a temperature reading.
THERM
Limit and Hysteresis
Contains the temperature value at which THERM
is asserted and indicates the level of hysteresis.
Look-up Table
Used to program the look-up table for the fan speed-to-temperature profile.
THERM
% On-time and
THERM
% Limit
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.
