Function
High temperature limit for the local zone.
Operation
Read/write
Power-up default value: 0011 1100_b = 3C_h (60°C)
Read/write command byte: 0000 0101_b = 05_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.
