APPLICATION NOTE: When measuring a 65nm Intel CPUs, the Ideality Setting should be the default 12h. When

measuring 45nm Intel CPUs, the Ideality Setting should be 15h.

5.15 High Limit Status Register

The High Limit Status Register contains the status bits that are set when a temperature or voltage

channel high limit is met or exceeded. If any of these bits are set, the HIGH status bit in the Status

been removed. Reading from the register will also clear the HIGH status bit in the Status Register if

the error condition has been removed.

If not masked, the ALERT pin will be set if the programmed number of consecutive alert counts have

been met and any of these status bits are set. Once set, the status bits will remain set until read unless

the ALERT pin is configured as a comparator output (see Section 4.4.2).

Bit 7 - VSENSE_HIGH - This bit is set when the VSENSE value meets or exceeds its programmed high

limit.

Bit 6 - VSRC_HIGH - This bit is set when the VSOURCE value meets or exceeds its programmed high

limit.

Bit 1 - E1HIGH - This bit is set when the External Diode 1 channel meets or exceeds its programmed

high limit.

Bit 0 - IHIGH - This bit is set when the Internal Diode channel meets or exceeds its programmed high

limit.
