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.
IN
Clock pin of SMBus circuitry, 5V tolerant.
I/O
Data pin for SMBus circuitry, 5V tolerant.
IN
Frequency select latch input pin
Dynamic Over Clocking pin: real time frequency selection 0: Normal; 1:
Frequency will transition to a preprogrammed value in the I2c. / Output
enable for PCI Express (SRC) outputs. SMBus selects which outputs are
controlled.
0 = enabled, 1 = tri-stated
