Table 54. REGISTER 0X12, REMOTE 2 LOW LIMIT, POWER-ON DEFAULT 0X54, LOCK = N, S/W RESET = N

Bit

Name

R/W

Description

<7:0> Remote 2 Low Limit

R/W When the Remote 2 temperature falls below this temperature, the corresponding

interrupt status bit is set.

Table 55. REGISTER 0X13, REMOTE 2 THERM LIMIT, POWER-ON DEFAULT 0X95, LOCK = Y, S/W RESET = N

Bit

Name

R/W

Description

<7:0> Remote 2 THERM

Limit

R/W When the Remote 2 temperature exceeds this temperature, the corresponding status bit

is set and the THERM output is activated.

Table 56. REGISTER 0X16, LOCAL OFFSET REGISTER, POWER-ON DEFAULT 0X00, LOCK = Y, S/W RESET = N

Bit

Name

R/W

Description

<7:0> Local Offset

R/W Allows a twos compliment offset to be automatically added to or subtracted from the

local temperature measurement. Resolution = 0.125C. Maximum offset from −16C to

+15.875C. Default = 0.

Table 57. REGISTER 0X17, REMOTE 1 OFFSET REGISTER, POWER-ON DEFAULT 0X00, LOCK = Y, S/W RESET = N

Bit

Name

R/W

Description

<7:0> Remote 1 Offset

R/W Allows a twos compliment offset to be automatically added to or subtracted from the

Remote 1 temperature measurement. Resolution = 0.125C.

Maximum offset from −16C to +15.875C. Default = 0.

Table 58. REGISTER 0X18, REMOTE 2 OFFSET REGISTER, POWER-ON DEFAULT 0X00, LOCK = Y, S/W RESET = N

Bit

Name

R/W

Description

<7:0> Remote 2 Offset

R/W Allows a twos compliment offset to be automatically added to or subtracted from the

Remote 2 temperature measurement. Resolution = 0.125C.

Maximum offset from −16C to +15.875C. Default = 0.

Table 59. REGISTER 0X19, THERM TIMER % LIMIT, POWER-ON DEFAULT 0XFF, LOCK = Y, S/W RESET = N

Bit

Name

R/W

Description

<7:0> THERM Timer on%

Limit

R/W If the THERM is asserted for greater than this limit on the time window, the

corresponding status bit is set.

Table 60. REGISTER 0X1A, THERM HYSTERESIS, POWER-ON DEFAULT 0X05, LOCK = Y, S/W RESET = N

Bit

Name

R/W

Description

<7:4>

<3:0>

Reserved

THERM Hysteresis

R

Reserved

R/W An unsigned THERM hysteresis value, LSB = 1C. Once THERM has been activated

on a temperature channel, the THERM limit – hysteresis is deactivated if the

temperature drops below THERM.
