Sets the limit comparison hysteresis for zone 1 for both
the High and Low limits. The hysteresis can be set from
0°C to 15°C and has 1°C resolution.
Sets the limit comparison hysteresis for zone 2 for both
the High and Low limits. The hysteresis can be set from
0°C to 15°C and has 1°C resolution.
Sets the limit comparison hysteresis for zone 3 for both
the High and Low limits. The hysteresis can be set from
0°C to 15°C and has 1°C resolution.
Sets the limit comparison hysteresis for zone 4 for both
the High and Low limits.The hysteresis can be set from
0°C to 15°C and has 1°C resolution.

6-bit signed 2’s complement offset adjustment. This
value is added to zone 1b or zone 2b temperature
measurements as they are made. All LM96194 registers
and functions behave as if the resulting temperature was
the true measured temperature. This register allows
offset adjustments from +31°C to −32°C in 1°C steps.
