Data ready event mask
1 = enabled, 0 = disabled
Local high temperature event mask
1 = enabled, 0 = disabled
Local low temperature event mask
1 = enabled, 0 = disabled
Remote high temperature event mask
1 = enabled, 0 = disabled
Remote low temperature event mask
1 = enabled, 0 = disabled
Diode fault mask
1 = enabled, 0 = disabled
Remote over-temperature event mask
1 = enabled, 0 = disabled
Local over-temperature event mask
1 = enabled, 0 = disabled
Power-up default value:
Read/Write command byte:
0000 0111_b = 07_h (Over-temp. and diode faults enabled)
0000 0100_b = 04_h

D[7:0]
High temperature limit for the local zone.

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 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.
