PD, POWER DOWN
turning off the VCO. In PD de-assertion all clocks will start without glitches.
PCI STOP FUNCTIONALITY
If PCIF (2:0) and SRC clocks are set to be free-running through SMBus programming, they will ignore the PCI_STOP register bit.
PD ASSERTION
IDTCV126
PROGRAMMABLE FLEXPC CLOCK FOR P4 PROCESSOR
PD is an asynchronous active high input used to shut off all clocks cleanly prior to clock power. When PD is asserted high all clocks will be driven low before
