Functional Description
Termination
Diode connections to external SMBus microcontroller for
–
monitoring IC thermal characteristics.
These balls are only for maintaining pin-compatibility with earlier
– generations of AMD IGPs or chipsets. They can either be
connected to a 3.3V rail or left unconnected on RX881 systems.
