Vtt_PwrGd# is an active low input used to determine when latched inputs are
ready to be sampled. PD is an asynchronous active high input pin used to put
the device into a low power state. The internal clocks, PLLs and the crystal
oscillator are stopped.
Clock pin of SMBus circuitry, 5V tolerant.
Data pin for SMBus circuitry, 5V tolerant.
Frequency select latch input pin
Output enable for PCI Express (SRC) outputs. SMBus selects which outputs
are controlled.
0 = enabled, 1 = tri-stated
