Function
Low temperature limit for the remote zone, least significant bits.
Reserved
Operation
Read/write
Always reads as zero
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 0000b. See Temperature Data Format 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 0000b. See Temperature Data Format for more details.
Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.
