APPLICATION NOTE: When measuring a 65nm Intel CPU, the Ideality Setting should be the default 12h. When
measuring a 45nm Intel CPU, the Ideality Setting should be 15h.
Bit 1 - E1HIGH - This bit is set when the External Diode 1 channel exceeds its programmed high limit.
Bit 0 - IHIGH - This bit is set when the Internal Diode channel exceeds its programmed high limit.
Bit 1 - ELOW - This bit is set when the External Diode channel drops below its programmed low limit.
Bit 0 - ILOW - This bit is set when the Internal Diode channel drops below its programmed low limit.
Bit 1 - ETHERM - This bit is set when the External Diode channel exceeds its programmed Therm
Limit. When set, this bit will assert the THERM pin.
Bit 0- ITHERM - This bit is set when the Internal Diode channel exceeds its programmed Therm Limit.
When set, this bit will assert the THERM pin.
