Basic capability
– 0 = Alarm and critical trips turned OFF.
– 1 = Alarm and critical trips turned ON.
Accuracy
– 0 = Accuracy ±2 °C over the active range and ±3 °C over the monitoring range
– 1 = High accuracy ±1 °C over the active range and ±2 °C over the monitoring range
Range width
– 0 = Values lower than 0 °C will be clamped and represented as binary value '0'.
– 1 = Temperatures below 0 °C can be read and the Sign bit will be set accordingly.
Temperature resolution
– 00 = 9 bit, 0.5 °C/LSB
– 01 = 10 bit, 0.25 °C/LSB - default resolution
– 10 = 11 bit, 0.125 °C/LSB
– 11 = 12 bit, 0.0625 °C/LSB

TMOUT - bus timeout support (for temperature sensor only)
– 0 = t
– 1 = Default for STTS2002-SMBus compatible 25 ms - 35 ms
Note: Timeout is not required for EEPROM component
EVSD - EVENT behavior upon shutdown
– 0 = Default for STTS2002. The EVENT output freezes in its current state when
– 1 = EVENT output is deasserted (not driven) when entering shutdown and remains
Reserved
These values must be set to '0'.

entering shutdown. Upon entering shutdown, the EVENT output remains in the
previous state until the next thermal data conversion or possibly sooner if EVENT is
programmed for comparator mode.

sooner if EVENT is programmed for comparator mode.
