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.
A 1 indicates that the Remote 2 high limit has been tripped.
A 1 indicates that the Remote 2 low limit has been tripped.
A 1 indicates that a short or an open has been detected on the Remote 2
temperature channel. This test is completed once on each conversion.
