Reserved.

3-Bit PECI Temperature Cycle Value. These three bits define the delay time between making

subsequent T_MINadjustments in the control loop for the PECI temperature channels in terms of

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.

PHTP

PECI

R/W

PHTR1 = 1 copies the PECI0 current reading to the PECI 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 PECI operating point register reflects

its programmed value.

PECI = 1 enables dynamic T_MINcontrol on the PECI temperature channel. The chosen T_MINvalue is

dynamically adjusted based on the current temperature, operating point, and high and low limits for

this zone.

PECI = 0 disables dynamic T_MINcontrol. The T_MINvalue chosen is not adjusted and the channel behaves

as described in the Automatic Fan Control Overview section.

¹This 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.

Table 90. Register 0x94—PECI0 Temperature Offset (Power-On Default = 0x00)

Bit No. R/W¹

[7:0] R/W

Description

Allows a temperature offset to be automatically applied to the PECI0 channel measurements. The programmable

offset range is from −63°C to +127°C with 1°C resolution.

¹This register becomes read-only when the Configuration Register 1 (0x40) LOCK bit is set to 1. Any further attempts to write to this register have no effect.

Table 91. Register 0x95—PECI1 Temperature Offset (Power-On Default = 0x00)

Bit No. R/W¹

[7:0] R/W

Description

Allows a temperature offset to be automatically applied to the PECI1 channel measurements. The programmable

offset range is from −63°C to +127°C with 1°C resolution.

¹This register becomes read-only when the Configuration Register 1 (0x40) LOCK bit is set to 1. Any further attempts to write to this register have no effect.

R/W

Allows a temperature offset to be automatically applied to the PECI2 channel measurements. The

programmable offset range is from −63°C to +127°C with 1°C resolution.

¹This register becomes read-only when the Configuration Register 1 (0x40) LOCK bit is set to 1. Any further attempts to write to this register have no effect.

Table 93. Register 0x97—PECI3 Temperature Offset (Power-On Default = 0x00)

Bit No. R/W¹

[7:0] R/W

Description

Allows a temperature offset to be automatically applied to the PECI3 channel measurements. The programmable

offset range is from −63°C to +127°C with 1°C resolution.

¹This register becomes read-only when the Configuration Register 1 (0x40) LOCK bit is set to 1. Any further attempts to write to this register have no effect.
