POWER AND THERMAL MANAGEMENT
•THERMTRIP# Interrupt Enable (bit 2, R/W) — When a catastrophic cooling failure
occurs, the processor will automatically shutdown. Bit2 =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.
