When the Remote 1 temperature exceeds this temperature, the corresponding status bit
is set and the THERM output is activated.
Allows a twos compliment offset to be automatically added to or subtracted from the
local temperature measurement. Resolution = 0.125°C. Maximum offset from -16°C to
+15.875°C. Default = 0.
Allows a twos compliment offset to be automatically added to or subtracted from the
Remote 1 temperature measurement. Resolution = 0.125°C. Maximum offset from
-16°C to +15.875°C. Default = 0.
If the THERM is asserted for greater than this limit on the time window, the
corresponding status bit is set.
Reserved.
An unsigned THERM hysteresis value, LSB = 1°C. Once THERM has been activated
on a temperature channel, the THERM limit – hysteresis is deactivated if the
temperature drops below THERM.
