PCI_STP# Assertion
[1]
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
SU
). (See
Figure 10
.) The PCIF clocks will not be affected by this pin if
their corresponding control bit in the SMBus register is set to
allow them to be free running.
PCI_STP# Deassertion
The deassertion of the PCI_STP# signal will cause all PCI and
stoppable PCIF clocks to resume running in a synchronous
manner within two PCI clock periods after PCI_STP# transi-
tions to a high level. (See
Figure 11
.)
Note:
1. The PCI STOP function is controlled by two inputs. One is the device PCI_STP# pin number 55 and the other is SMBus byte6 bit 3. These two inputs are logically
OR’ed. If either the external pin or the internal SMBus register bit is set LOW then the stoppable PCI clocks will be stopped in a logic LOW state.
