Differential Processor Core Clock Negative Phase: These pins receive a
low-voltage differential host clock from the external clock synthesizer. This
clock is used by all of the MCH logic that is in the Host clock domain.
Differential Processor Core Clock Positive Phase: These pins receive a
low-voltage differential host clock from the external clock synthesizer. This
clock is used by all of the MCH logic that is in the Host clock domain.
Core VCC: Analog Voltage for the PLL
Core VSS: Analog Voltage for PLL
Error Output: Error output signal:
ERR[0] = Correctable and recoverable error from the memory subsystem
ERR[1] = Uncorrectable error from the
ERR[2] = Fatal error from the
