D[7:4]
Low temperature limit for the remote zone, least significant bits.

D[3:0]
Reserved
Always reads as zeros.
Power-up default value:
0000 0000_b = 00_h (0°C)
Read/Write command byte: 0001 0100_b = 14_h
Each LSB represents one-sixteenth degree centigrade. The values are in a binary format such that 1/16th°C (0.0625°C) is
reported as 0001 0000_b. See Temperature Data Format (above) for more details.
Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.

Power-up default value:
0110 0100_b = 64_h (100°C)
Read/Write command byte: 0001 1001_b = 19_h
Each LSB represents one degree centigrade. The values are in a two’s complement binary format such that 0°C is reported
as 0000 0000_b. SeeTemperature Data Format (above) for more details.
Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.
