This read−only value contains the company ID, which is 0x41.
This read−only value contains the revision ID.
Represents the % time of THERM activity within the time window set by the
configuration bits.
A 1 indicates that the local high limit has been tripped.
A 1 indicates that the local low limit has been tripped.
A 1 indicates that the Remote 1 high limit has been tripped.
A 1 indicates that the Remote 1 low limit has been tripped.
A 1 indicates that a short or an open has been detected on the Remote 1
temperature channel. This test is completed once on each conversion.
This register contains the LSBs of the last measured local temperature value.
Resolution = 0.03125°C.
This register contains the MSBs of the last measured local temperature value.
Resolution = 1°C.
This register contains the LSBs of the last measured Remote 1 temperature
value. Resolution = 0.03125°C.
This register contains the LSBs of the last measured Remote 1 temperature
value. Resolution = 1°C.
