Power-up state = 0
The master can write to this bit, but it will always read out as a 0.
Power-up state = 0
Sets conversion resolution (see Table 4)
Power-up state = 0
Sets conversion resolution (see Table 4)
Power-up state = 0
Sets the thermostat fault tolerance (see Table 5).
Power-up state = 0
Sets the thermostat fault tolerance (see Table 5).
Power-up state = 0
POL = 0 — O.S. is active low.
POL = 1 — O.S. is active high.
Power-up state = 0
TM = 0 — Comparator mode.
TM = 1 — Interrupt mode.
See the OPERATION–Thermostat section for a detailed description of
these modes.
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.
