Local Temperature Low Limit Register (TLOW0)

8-bits, read/write

Local Temperature Low Limit Register

D[7]

D[6]

D[5]

D[4]

D[3]

D[2]

D[1]

D[0]

read/write

Low temperature limit for local zone

Bit

Function

Operation

D[7:0]

Low temperature limit for the local zone

Read/write

Power-up default value:

0000 0000b = 00h (0°C)

Read/Write command byte:

0000 0110b = 06h

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 (above) for more details.

Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.

Remote Temperature High Limit High-Byte Register (THIGH1h)

8-bits, read/write

Remote Temperature High Limit High-Byte Register

D[7]

D[6]

D[5]

D[4]

D[3]

D[2]

D[1]

D[0]

read/write

High temperature limit for remote zone, most signiﬁcant byte.

Bit

Function

Operation

D[7:0]

High temperature limit for the remote zone, most signiﬁcant byte.

Read/write

Power-up default value:

0101 0000b = 50h (80°C)

Read/Write command byte:

0000 0111b = 07h

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 (above) for more details.

Any writes to a temperature limit register will result in the corresponding fault queue being purged and reset.
