POWER AND THERMAL MANAGEMENT

• THERMTRIP# Interrupt Enable (bit 2, R/W) — When a catastrophic cooling failure

occurs, the processor will automatically shutdown. Bit 2 = 0 disables the feature; bit 2 = 1

enables the feature.

• FORCPR# Interrupt Enable (bit 3, R/W) — When a source external to the processor

asserts PROCHOT#, the processor will throttle. Bit 3 = 0 disables the feature; bit 3 = 1

enables the feature.

• Overheat Interrupt Enable (bit 4, R/W) — Enables the generation of an interrupt when

an overheat temperature [>Tj(Max)] is reached. Bit 4 = 0 disables the feature; bit 4 = 1

enables the feature.

• Threshold #1 Value (bits 14:8, R/W) — A temperature relative to Tj(Max) used to

generate an interrupt when the Threshold #1 Interrupt Enable bit is set and the actual

relative temperature reaches or crosses this value.

• Threshold #1 Interrupt Enable (bit 15, R/W) — Enables the generation of an interrupt

when the actual temperature relative to Tj(Max) reaches the value specified in Threshold

#1 value. Bit 15 = 0 disables the feature; bit 15 = 1 enables the feature.

• Threshold #2 Value (bits 22:16, R/W) — A temperature relative to Tj(Max) used to

generate an interrupt when the Threshold #2 Interrupt Enable bit is set and the actual

relative temperature reaches or crosses this value.

• Threshold #2 Interrupt Enable (bit 23, R/W) — Enables the generation of an interrupt

when the actual temperature relative to Tj(Max) reaches the value specified in Threshold

#2 value. Bit 23 = 0 disables the feature; bit 23 = 1 enables the feature.
