Table 3. Configuration Register Bit Descriptions
BIT NAME
FUNCTIONAL DESCRIPTION
0
Reserved
Power-up state = 0
The master can write to this bit, but it will always read out as a 0.
R1
Conversion Resolution Bit 1
Power-up state = 0
Sets conversion resolution (see Table 4)
R0
Conversion Resolution Bit 0
Power-up state = 0
Sets conversion resolution (see Table 4)
F1
Thermostat Fault Tolerance Bit 1
Power-up state = 0
Sets the thermostat fault tolerance (see Table 5).
F0
Thermostat Fault Tolerance Bit 0
Power-up state = 0
Sets the thermostat fault tolerance (see Table 5).
POL
Thermostat Output (O.S.) Polarity
Power-up state = 0
POL = 0  O.S. is active low.
POL = 1  O.S. is active high.
TM
Thermostat Operating Mode
Power-up state = 0
TM = 0  Comparator mode.
TM = 1  Interrupt mode.
See the OPERATIONThermostat section for a detailed description of
these modes.
SD
Shutdown
Power-up state = 0
SD = 0  Active conversion and thermostat operation.
SD = 1  Shutdown mode.
See the SHUTDOWN  MODE section for a detailed description of this
mode.
