Table 39. Register 0x0B — Dynamic TMIN Control Register 1 (Note 1)

Bit

Name

R/W

Description

Remote 1 En

R/W

Setting this bit to 1 enables dynamic TMIN control for the Remote 1 channel. Default = 0.

Remote 2 En

R/W

Setting this bit to 1 enables dynamic TMIN control for the Remote 2 channel. Default = 0.

P1R1

R/W

P1R1 = 1 copies the Remote 1 current temperature to the Remote 1 operating point register if

THERM1 is asserted externally. This happens only if the current temperature is less than the

value in the operating point register. The operating point contains the temperature at which

THERM1 is asserted. P1R1 = 0 (default) ignores any THERM1 assertions on the THERM1 pin.

The Remote 1 operating point register reflects its programmed value.

P1R2

R/W

P1R2 = 1 copies the Remote 2 current temperature to the Remote 2 operating point register if

THERM1 is asserted externally. This happens only if the current temperature is less than the

value in the operating point register. The operating point contains the temperature at which

THERM1 is asserted. P1R2 = 0 (default) ignores any THERM1 assertions on the THERM1 pin.

The Remote 2 operating point register reflects its programmed value.

P2R1

R/W

P2R1 = 1 copies the Remote 1 current temperature to the Remote 1 operating point register if

THERM2 is asserted externally. This happens only if the current temperature is less than the

value in the operating point register. The operating point contains the temperature at which

THERM2 is asserted. P2R1 = 0 (default) ignores any THERM2 assertions on the THERM2 pin.

The Remote 1 operating point register reflects its programmed value.

P2R2

R/W

P2R2 = 1 copies the Remote 2 current temperature to the Remote 2 operating point register if

THERM2 is asserted externally. This happens only if the current temperature is less than the

value in the operating point register. The operating point contains the temperature at which

THERM2 is asserted. P2R2 = 0 (default) ignores any THERM2 assertions on the THERM2 pin.

The Remote 2 operating point register reflects its programmed value.
