PCI_STP# Assertion
The PCI_STP# signal is an active LOW input used for
synchronous stopping and starting the PCI outputs while the
rest of the clock generator continues to function. The set-up
time for capturing PCI_STP# going LOW is 10 ns (t
setup
) (see
Figure 14
.) The PCI_F (0:2) clocks will not be affected by this
pin if their control bits in the SMBus register are set to allow
them to be free running.
