Configuration 2 Register
The Configuration 2 Register controls conversion rate of the temperature monitoring as well as the
fault queue.
Bit 6 - DIS_DYN - Disables the Dynamic Averaging Feature.
‘0’ (default) - The Dynamic Averaging function is enabled. The conversion time for all temperature
channels is scaled based on the chosen conversion rate to maximize accuracy and immunity to
random temperature measurement variation.
‘1’ - The Dynamic Averaging function is disabled. The conversion time for all temperature channels
is fixed regardless of the chosen conversion rate.
Bit 5 - DIS_TO - Disables the SMBus time out function.
‘0’ (default) - The SMBus time out function is enabled.
‘1’ - The SMBus time out function is disabled allowing the device to be fully I2C compliant.
Bit 4 - DIS_AVG - Disables digital averaging of the External Diode channels.
‘0’ (default) - The External Diode channels have digital averaging enabled. The temperature data
is the average of the previous four measurements.
‘1’ - The External Diode channels have digital averaging disabled. The temperature data is the last
measured data.
Bits 3-2 - QUEUE[1:0] - Determines the number of consecutive out of limit conditions that are
necessary to trigger an interrupt. Each measurement channel has a separate fault queue associated
with the high limit, low limit, and diode fault condition.
APPLICATION NOTE: If the fault queue for any channel is currently active (i.e. an out of limit condition has been
detected and caused the fault queue to increment) then changing the settings will not take
effect until the fault queue is zeroed. This occurs by the ALERT pin asserting or the out of
limit condition being removed.
Bit 1 - 0 - CONV[1:0] - determines the conversion rate of the temperature monitoring. This conversion
rate does not affect the fan driver. The supply current from VDD_3V is nominally dependent upon the
conversion rate and the average current will increase as the conversion rate increases.
