Description
MSB of 3-bit Remote 2 Cycle Value. The other two bits of the code reside in Dynamic T MIN
Control Register 2 (0x8F). These three bits define the delay time between making
subsequent T MIN adjustments in the control loop in terms of the number of monitoring cycles.
The system has associated thermal time constants that need to be found to optimize the
response of fans and the control loop.
V CCP LO = 1. When the power is supplied from 3.3 V STANDBY and the core voltage (V CCP )
drops below its V CCP low limit value (0x46), the following occurs:
Status Bit 1 in Status Register 1 is set.
SMBALER T is generated, if enabled.
PROCHOT monitoring is disabled.
Dynamic T MIN control is disabled.
The device is prevented from entering shutdown.
Everything is re-enabled once V CCP increases above the V CCP low limit.

PHTR1
R/W
PHTR1 = 1 copie s the Remote 1 current temperature to the Remote 1 operating point
register if THERM is asserted. The operating point contains the temperature at which
THERM is asserted, allowing the system to run as quietly as possible without affecting
system performance.
PHTR1 = 0 ignores any THERM assertions on the THERM pin. The Remote 1 operating
point register reflects its programmed value.
[3]
PHTL
R/W
PHTL = 1 copies the local channel’s current temperature to the local operating point register
if THERM is asserted. The operating point contains the temperature at which THERM is
asserted. This allows the system to run as quietly as possible without affecting system
performance.
PHTL = 0 ignores any THERM assertions on the THERM pin. The local temperature
operating point register reflects its programmed value.
[4]
PHTR2
R/W
PHTR2 = 1 copie s the Remote 2 current temperature to the Remote 2 operating point
register if THERM is asserted. The operating point contains the temperature at which
THERM is asserted, allowing the system to run as quietly as possible without affecting
system performance.
PHTR2 = 0 ignores any THERM assertions on the THERM pin. The Remote 2 operating
point register reflects its programmed value.
[5]
R1T
R/W
R1T = 1 enables dynamic T MIN control on the Remote 1 temperature channel. The chosen
T MIN value is dynamically adjusted based on the current temperature, operating point, and
high and low limits for this zone.
R1T = 0 disables dynamic T MIN control. The T MIN value chosen is not adjusted, and the
channel behaves as described in the section.
[6]
LT
R/W
LT = 1 enables dynamic T MIN control on the local temperature channel. The chosen T MIN
value is dynamically adjusted based on the current temperature, operating point, and high
and low limits for this zone.
LT = 0 disables dynamic T MIN control. The T MIN value chosen is not adjusted, and the
channel behaves as described in the Automatic Fan Control Overview section.
[7]
R2T
R/W
R2T = 1 enables dynamic T MIN control on the Remote 2 temperature channel. The chosen
T MIN value is dynamically adjusted based on the current temperature, operating point, and
high and low limits for this zone.
R2T = 0 disables dynamic T MIN control. The T MIN value chosen is not adjusted, and the
channel behaves as described in the Automatic Fan Control Overview section.
1. This register becomes read-only when the Configuration Register 1 (0x40) Lock bit is set to 1. Any subsequent attempts to write to this
register fail.
