BIT NAME FUNCTION
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 3)
R0
Conversion Resolution Bit 0
Power-up state = 0
Sets conversion resolution (see Table 3)
F1
Thermostat Fault Tolerance Bit 1
Power-up state = 0
Sets the thermostat fault tolerance (see Table 4).
F0
Thermostat Fault Tolerance Bit 0
Power-up state = 0
Sets the thermostat fault tolerance (see Table 4).
POL
Thermostat Output (OS) Polarity
Power-up state = 0
POL = 0 — OS is active low.
POL = 1 — OS is active high.
TM
Thermostat Operating Mode
Power-up state = 0
TM = 0 — Comparator mode
TM = 1 — Interrupt mode
See the Thermostat 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.
