Description
MSB of 3-Bit Remote 2 Cycle Value. The other two bits of the code reside in Dynamic T
Control Register 2 (Reg. 0x37). These three bits define the delay time between making sub-
sequent T
The system will have associated thermal time constants that need to be found to optimize
the response of fans and the control loop.

PHTR1 = 1 copies the Remote 1 current temperature to the Remote 1 Operating Point
Register if THERM gets asserted. The operating point will contain the temperature at
which THERM is asserted. This allows the system to run as quietly as possible without
system performance being affected. PHTR1 = 0 ignores any THERM assertions on the
THERM pin. The Remote 1 Operating Point Register will reflect its programmed value.
PHTL = 1 copies the local channel’s current temperature to the Local Operating Point
Register if THERM gets asserted. The operating point will contain the temperature at
which THERM is asserted. This allows the system to run as quietly as possible without
system performance being affected. PHTL = 0 ignores any THERM assertions on the
THERM pin. The Local Temp Operating Point Register will reflect its programmed value.
PHTR2 = 1 copies the Remote 2 current temperature to the Remote 2 Operating Point
Register if THERM gets asserted. The operating point will contain the temperature at
which THERM is asserted. This allows the system to run as quietly as possible without
system performance being affected. PHTR2 = 0 ignores any THERM assertions on the
THERM pin. The Remote 2 Operating Point Register will reflect its programmed value.
